Detailed Description
In order to make the technical solution of the present application better understood by those skilled in the art, the technical solution of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, shall fall within the scope of the present application.
The embodiment of the application provides a three-bit gate position information updating method of a quantum computing cloud platform. The method is based on a VUE front end development framework, is completed by using a JavaScript programming language, and adopts a quantum computing cloud platform as an execution subject.
As shown in fig. 1, the method for updating three-bit gate position information of the quantum computing cloud platform specifically includes steps S101-S104:
And S101, displaying the three-bit gate at a corresponding position of the quantum register according to the initial position information of the configured three-bit gate.
Specifically, firstly, a popup window function is introduced into an editing interface of the quantum computing cloud platform through a ElementUI framework. And after receiving the position configuration instruction of the three-bit gate, the quantum computing cloud platform pops up the position information configuration popup window of the three-bit gate in the editing interface. The position information configuration popup window comprises a starting position, a middle position and an ending position of the three-bit door. The starting position, the middle position and the ending position are distributed to correspond to the quantum register serial number of the first bit gate, the quantum register serial number of the second bit gate and the quantum register serial number of the third bit gate in the three bit gates.
In one embodiment, fig. 2 is a schematic diagram of an initial position of a three-bit gate according to an embodiment of the present application, as shown in fig. 2, in a top row of icons in the figure, except for the last two icons, the remaining icons represent different single-bit gates, and the english symbol of each icon in the figure is only set for distinction, and does not specifically refer to which single-bit gate. While the last two icons represent three-bit gates, each representing a different three-bit quantum gate. In the bit gate addition interface, q [0], q [1], q [2], q [3], q [4] respectively represent five different quantum registers, and the horizontal line behind each quantum register represents the corresponding space of each quantum register for placing a bit gate. Clicking on the left minus sign can delete the corresponding quantum register and clicking on the lowest plus sign can add a new quantum register. In the dashed line box in fig. 2, three bit gates 1 are shown, and since the three bit gates of the three bit gates 1 are respectively located in the quantum registers q [0], q [1], q [2], the initial positions of the three bit gates 1 are: starting position: 0. intermediate position: 1. end position: 2.
Further, initial position information input by an operator in the position information configuration popup is received, and each of the three-bit gates is displayed on a corresponding quantum register, respectively.
In one embodiment, fig. 3 is a schematic view of a three-bit door position information configuration popup according to an embodiment of the present application. Clicking on the pen-shaped button next to the three-bit gate in fig. 2 ejects the position information configuration popup as shown in fig. 3. As shown in fig. 3, the location information configuration window includes three input boxes, which are a start location, a middle location, and an end location. The operator inputs the serial numbers of the quantum registers in each input box respectively, and the background can directly display each bit gate of the three-bit gates on the corresponding quantum register.
The lateral position of the three-bit gate on the quantum register is determined by the position of the operator's drag, to which lateral position the operator drags the three-bit gate icon, and in which lateral position the three-bit gate is displayed. The three-bit gate position referred to in the present application refers to the longitudinal position of the three-bit gates, i.e. on which quantum register the three of the three-bit gates are located, respectively.
Further, the initial position information is recorded in the HTML code of the three-bit gate as a current position attribute of the three-bit gate. And when the position information of the three-bit door is updated each time, the updated position information is also stored in the HTML code and replaces the current position attribute, so that an operator can acquire the current position attribute and pre-display the current position attribute in an input frame of the position information configuration popup window when the position information is updated, and the operator is prompted about the current position of the three-bit door.
For example, if the current position is 0,1, 2, when the operator clicks the edit button, the popped position information is configured in the input box of the pop-up window, and the current position of the three-bit door is pre-displayed as 0,1, 2, so that the operator can modify according to the current position, and is not likely to forget the current position of the three-bit door after the pop-up window pops up.
S102, receiving updated position information of the three-bit gate.
Specifically, after receiving the position update instruction of the three-bit gate, the position information configuration window of the three-bit gate is popped up again in the editing interface. Updated location information entered by the operator in the location information configuration window is then received.
As a possible implementation, the location update instruction is triggered after clicking a pen-shaped button next to a three-bit gate as shown in fig. 2.
S103, determining a corresponding position information updating rule according to the updating type and the position type of the three-bit gate;
First, according to the received update position information, the update type of the three-bit gate is judged. The method comprises the following steps: and determining the quantum register serial number corresponding to the initial position in the updated position information as a first updated serial number. And determining the quantum register serial number corresponding to the end position in the updated position information as a second updated serial number. And determining the sequence number of the quantum register corresponding to the initial position in the initial position information or the last updated position information as a first current sequence number. And determining the quantum register serial number corresponding to the end position in the initial position information or the last updated position information as a second current serial number.
Further, if the first update sequence number is smaller than the first current sequence number and the second update sequence number is greater than or equal to the second current sequence number, the update type of the three-bit gate is an extension type; if the first update sequence number is equal to the first current sequence number and the second update sequence number is greater than the second current sequence number, the update type of the three-bit gate is an extension type; if the first updating sequence number is larger than the first current sequence number and the second updating sequence number is smaller than or equal to the second current sequence number, the updating type of the three-bit gate is a shrinkage type; if the first update sequence number is greater than the first current sequence number and the second update sequence number is less than the second current sequence number, the update type of the three-bit gate is a shrink type.
In one embodiment, if the current starting position of the three-bit gate is 1 and the ending position is 4. Then there are three cases where the update type is an extension type: (1) The updated starting position is equal to 1, and the ending position is greater than 4; (2) The updated starting position is less than 1, and the ending position is greater than 4; (3) The updated starting position is less than 1 and the ending position is equal to 4. There are also three cases where the update type is a shrink type: (1) The updated starting position is equal to 1, and the ending position is less than 4; (2) The updated starting position is greater than 1, and the ending position is less than 4; (3) The updated starting position is greater than 1 and the ending position is equal to 4.
Further, in the case that no other bit gates exist in the column where the three bit gates currently exist, each bit gate of the three bit gates is updated to the corresponding quantum register according to the updated position information.
In one embodiment, as shown in fig. 2, the column where the three-bit gate 1 is located has no other bit gate, and no matter whether the update type of the three-bit gate 1 is expanded or contracted, the three-bit gate 1 can be directly updated without changing the positions of the other bit gates.
And under the condition that other bit gates exist in the column of the three-bit gate, judging the update type of the three-bit gate according to the update position information. If the update type is an extension type and other bit gates are arranged at the update positions of three bit gates in the extended three bit gates, the update positions and the original bit gates behind the update positions are shifted backwards by one position, and each bit gate of the three bit gates is updated to the corresponding quantum register respectively.
In one embodiment, as shown in FIG. 4, the initial position of the three-bit gate is: starting position: 0. intermediate position: 1. end position: 4. at this point, if the three-bit gate is to be extended, the end position is updated onto quantum register q [5], and it is seen that there is a single-bit gate X at the column position of quantum register q [5 ]. At this time, the original single-bit gate X at the position needs to be shifted backward by one position, and the subsequent single-bit gates Z also need to be shifted backward in sequence. The updated individual bit gate positions are shown in fig. 5.
And under the condition that the update type of the three-bit gates is the contraction type, if other bit gates are arranged behind the third bit gate in the three-bit gates, respectively updating each bit gate of the three-bit gates to the corresponding quantum register according to the update position information. And sequentially forward shifting all bit gates behind the original position of the third bit gate by one position.
In one embodiment, as shown in FIG. 6, the initial position of the three-bit gate is: starting position: 0. intermediate position: 1. end position: 5. at this time, if the three-bit gate is to be contracted, the end position is updated to the quantum register q [2], and it is seen that the column position of the quantum register q [5] is followed by a single-bit gate X and a single-bit gate Z, then after the three-bit gate is contracted, the single-bit gate X and the single-bit gate Z need to be sequentially shifted forward by one position. The updated individual bit gate positions are shown in fig. 7.
And S104, updating the position of the three-bit door based on the updated position information and the position information updating rule.
Specifically, an array is created in each quantum register, each array for storing bit gate information on the corresponding quantum register. Wherein each element in the array corresponds to one bit of gate information.
Further, each of the three-bit gates is updated to a corresponding quantum register according to the previously determined update location information and location information update rules.
Further, for the quantum register added with the bit gate, the insert element operation is performed on the corresponding array. And for the quantum register with reduced bit gates, deleting elements of the corresponding array. The three-bit gate can be ensured to be displayed on the page correctly according to the development requirement after being edited, and the development purpose is achieved.
