Example 1
The embodiment of the application provides a quantum route editing method which can be applied to various clients with display screens, including but not limited to mobile phones, tablet computers, portable computers and desktop computers. The client side realizes quantum line editing by interacting with the use object, the use object sends an operation instruction by touching a display screen of the client side, and the client side realizes interaction with the use object according to the corresponding operation instruction.
Referring to fig. 1, which is a schematic flow chart of a quantum wire editing method according to an embodiment of the present application, referring to fig. 1, the quantum wire editing method may include the following steps:
s101: and responding to a touch instruction of any quantum gate component in the quantum gate selection column, storing attribute information of the quantum gate component into a preset editing data object, and generating a quantum gate component mirror image.
In step S101, any one of the quantum gate components in the quantum gate selection field listens for a touch event in real time, and responds to a touch command to any one of the quantum gate components in the quantum gate selection field.
In a specific embodiment, the display screen of the client displays an operation interface of an application executing the quantum route editing method, and referring to fig. 2, at least the following areas are presented in the operation interface:
the area of the tag '1' is a quantum gate selection column, and the quantum gate assembly can be selected by dragging the quantum gate assembly in the area;
the area of the label '2' is the depth of the quantum circuit, and the depth position of the current quantum circuit can be clearly known from the area;
the region of the label "3" is the number of the quantum wire, Q0, Q2..qn respectively represents the quantum bit where the quantum wire is located, and "|0>" represents the initial state of the quantum bit;
The area of the label '4' is a corresponding bit measurement mark, and an icon in the area can be clicked to select whether to measure the projection probability of the corresponding bit or not;
the area of the tag '5' is a removal area of the quantum circuit, is invisible in a normal state, and is displayed when the quantum gate assembly image is dragged to the range of the removal area;
the area of the label '6' is a quantum wire editing area, and the operations of inserting, connecting, adjusting and deleting the quantum wire can be performed.
Taking the above client as an Android client as an example, the above operation interface may use the layout component RecyclerView, linearLayout in the Android SDK and the nestedscriolview to perform a combined layout, and the overall layout structure of the layout components in each region of the operation interface is as shown in fig. 3, and since the quantum circuit editing region needs to implement more quantum bits under the limited scope of the visualization region, the quantum circuit editing region uses the nestedscriolview layout component to perform a layout. The NestedScrollView layout component is used to implement a slide up and down to adjust the vertical region, and the RecycloView layout component is used to implement a slide left and right to adjust the lateral region to display a greater quantum depth.
After the operation interface is realized by the layout mode, a quantum gate component needs to be added in the quantum gate selection column. The quantum gate assembly realizes the display of the image of the quantum gate assembly by inheriting the public assembly, and adding ImageView, and for Rx, ry and Rz rotary quantum gates, the type and angle value of the quantum gate can be displayed by adding a TextView text assembly; the quantum gate type attribute, namely the type attribute, can be built in the quantum gate assembly, and different quantum gate assembly images can be displayed by setting different type attributes; a rotating quantum gate angle attribute, i.e., angle attribute, is created built into the quantum gate assembly. For example, for an image of an Ry rotary quantum gate, an angle value may be set at its upper right corner, representing the angle attribute of the quantum gate assembly.
After the quantum gate component is added in the quantum gate selection column, the quantum gate component needs to be dragged into a quantum gate slot of a quantum circuit editing area to realize the editing function of the quantum circuit. The quantum gate slot refers to a position for placing the quantum gate assembly, as shown in fig. 4, each square frame in the figure represents an area range of the quantum gate slot, the quantum gate slot can be realized by a custom View assembly, and the quantum gate slot has an attribute for recording a state of the assembly, namely, a state of the quantum gate slot.
After the function of the quantum gate slot is realized, a plurality of quantum gate slots are spliced together through the RecycloView layout component, so that a complete quantum circuit can be realized, as shown in FIG. 5, wherein the frame selection partial area is one quantum circuit.
In a specific embodiment, the attribute information GateInfo of the quantum gate assembly may be contained in a data packet in the following three-bit quantum gate assembly attribute information GateInfo data packet format:
{"angle":0.0,"controlQubit":-1,"controlQubit2":-1,"delay":0.0,"qubitIndex":0,"timeslot":0,"type":"CCNOT"}；
wherein:
the angle attribute information "angle" indicates the angle of the rotary quantum gate, such as the angle of Rx, ry and Rz rotary quantum gates, and corresponds to the value of the upper right corner of the rotary quantum gate assembly;
the control end attribute information of "control qubit" and "control qubit2" respectively represent two control endpoints of the three-bit gate, such as two control endpoints of the CCNOT, the control endpoints are connection points in a slot state, and the slot component can determine the state at the same depth position on other quantum bit lines according to the data of the quantum gate component in the slot;
the delay attribute information 'delay' represents the delay time of the delay quantum gate and corresponds to the numerical value of the upper right corner of the delay quantum gate assembly;
the quantum bit attribute information "qubit index" represents the quantum bit where the quantum gate assembly is located, and corresponds to Q0 to Q2..qn on the operation interface;
Depth attribute information "time" indicates a depth position on a quantum wire where the quantum gate assembly is located;
the type attribute information "type" indicates a corresponding quantum gate type, and icons on the quantum gate component display different icons according to this data. Quantum gate types such as H quantum gate, X quantum gate, and CNOT quantum gate.
In some other embodiments, for two-bit gates, only one "control qubit" is used to record one control endpoint of the two-bit gate, such as one control endpoint of the CNOT, representing another bit connected to the two-bit gate. And for single bit gates, control side attribute information is not included.
In step S101, any one of the quantum gate elements in the quantum gate selection field responds to the touch command, because the quantum gate element listens for the touch event onTouchEvent. After the quantum gate assembly responds to the touch instruction, attribute information GateInfo of the quantum gate assembly is stored into a preset editing data object, the preset editing data object can be set as a ClipData object, then a startDrag method of the quantum gate assembly is called, the ClipData object with the attribute information of the quantum gate assembly is transmitted to the startDrag method, meanwhile, a quantum gate assembly mirror image is generated, and at the moment, the quantum gate assembly mirror image carrying the ClipData object can be dragged.
In the embodiment of the application, if a quantum gate assembly inserted into any quantum gate slot in a quantum line editing area responds to a touch instruction, the attribute information of the quantum gate assembly is stored into a preset editing data object to generate a mirror image of the quantum gate assembly, and the quantum gate assembly of the quantum gate slot is subjected to image hiding.
S102: and responding to a dragging instruction of the quantum gate assembly mirror image, and dragging the quantum gate assembly mirror image and the preset editing data object to a quantum circuit editing area by a quantum gate selection column.

Here, the quantum gate component mirror images the attribute information GateInfo of the carrier quantum gate component.

And if the quantum gate slot monitoring is carried out so that the mirror image of the dragged quantum gate assembly is separated from the self area range, namely, the self area range of the quantum gate slot is removed by the mirror image of the quantum gate assembly is monitored again in the onDrag callback, the slot display of the quantum gate slot is converted from the second state to the first state. The first state is an initial state displayed before the quantum gate slot is not operated, and the second state is an intermediate process state displayed in the operation process of the quantum gate slot.

The first state may be "normal", and the third state may be "connect to click".
In the step S105, if the quantum gate assembly displayed in the quantum gate slot to be edited is a multi-bit quantum gate, the slot display of other quantum gate slots at the same depth as the quantum gate slot to be edited is converted from the first state to the third state, and the method further includes:

Wherein the fourth state is the "connected state".
In a specific embodiment, the quantum gate assembly placed in the quantum gate slot to be edited may be a CNOT quantum gate assembly, at this time, other quantum gate slots located at the same depth as the quantum gate slot to be edited are in a "connected to be clicked" state, as shown in fig. 12, after receiving a click operation instruction, the clicked quantum gate slot is connected to the quantum gate slot to be edited, and, as shown in fig. 13, a control qubit of the CNOT quantum gate assembly is set to a qubit index of attribute information GateInfo of the clicked quantum gate slot, and the slot displays of all quantum gate slots located on the connection line are converted from a "connected to be clicked" state to a fourth state, and the slot displays of the remaining quantum gate slots located outside the connection line are converted from a "connected to be clicked" state to be a first state, where the first state may be "normal", and the fourth state may be "selected and up connected" or "selected and down connected" according to the connection condition.
In the above step S105, the attribute information of the multi-bit quantum gate includes control side attribute information, and the method further includes:
judging whether the quantum bit of the quantum circuit where the quantum gate slot to be edited is located is larger than the quantum bit of the quantum circuit where the quantum gate slot after clicking is located;
if yes, modifying the control end attribute information of the quantum gate assembly of the quantum gate slot to be edited into upward connection;
and if not, modifying the attribute information of the control end of the quantum gate assembly of the quantum gate slot to be edited into downward connection.
In a specific embodiment, after the clicked quantum gate slot is connected with the quantum gate slot to be edited, whether the quantum bit of the quantum circuit where the quantum gate slot to be edited is located is larger than the quantum bit of the quantum circuit where the quantum gate slot to be edited is located is judged, namely whether the qubit index of the attribute information of the CNOT quantum gate assembly is larger than the control qubit is judged.

At this time, the slot states of other quantum gate slots on the connection line are in a 'connection state'.
After the data formats of the quantum gate assembly and the quantum circuit are set in the above manner, the quantum gate assembly needs to be dragged to the quantum circuit editing area in the operation interface, and due to the limited range of the visual area, as shown in fig. 14, more quantum bits need to be displayed in a rolling manner by sliding the quantum circuit editing area up and down, or more depths of the quantum circuit need to be displayed in a rolling manner by sliding the quantum circuit editing area left and right. In the layout of the operation interface, the display range is adjusted by realizing sliding through the RecycloView layout component. The quantum circuit diagram editing area is composed of a plurality of recurvew layout components, but because the single recurvew layout components are independent, and a sliding event is the behavior of the single recurvew layout components, it is critical to keep each recurvew layout component aligned, and based on the fact, the sliding of the quantum circuit editing area can be realized by the following steps:
And responding to the sliding instruction of the quantum gate editing area, and displaying the visual area range of the quantum gate editing area along with the sliding instruction.
Specifically, in the NestedScrollView, a plurality of RecycloerView (one bit line uses one RecycloerView) is nested to realize each bit, and the RecycloerView can realize the transverse scrolling of a single bit, but in order to realize the transverse scrolling of a plurality of bits (namely the whole editing area), the OnScrollLister method of the RecycloerView monitors to realize the linkage scrolling of a plurality of bits. First, each Recycloview listens for a sliding event using addOnScrollListener, where the onScrolled callback in OnScrollListener obtains the distance to the current Recycloview move in real time. Then, after the other recurrerview acquires the moving distance, the recurrerview is moved by the same distance along the same direction by using the scrollBy of the recurrerview, that is, each recurrerview is moved to the position before the next recurrerview is moved. The up and down scrolling of the edit area is accomplished using a NestedScrollView component that scrolls by gesture sliding up and down when the content exceeds the specified area.
By the method, the quantum circuit editing area can slide up and down and left and right, the expandability of the depth of the quantum circuit is realized, the depth and the number of the quantum circuits can be set at will, and the quantum gate assembly beyond the visualization area can be checked by only scratching the screen in the corresponding direction.

and responding to a dragging instruction for dragging the quantum gate assembly image of the quantum gate slot to be edited to the removing area range, and displaying the removing area.
After the removal area is displayed, the applicable object can select to execute the deletion operation or keep the quantum gate component moved to the deletion area, and based on this, the method can further comprise:
deleting the quantum gate component image in the quantum gate slot to be edited and the attribute information of the corresponding quantum gate component in the preset editing data object, or,
and responding to a release operation instruction after dragging the quantum gate assembly of the quantum gate slot to be edited out of the removal area, and reserving the quantum gate assembly mirror image in the quantum gate slot to be edited and attribute information of the corresponding quantum gate assembly in the preset editing data object.
