OPENQASM, full name Open Quantum Assembly Language, is an open source quantum assembly language. It was introduced by IBM in 2017, 7, on the quantum computing platform, to describe general quantum computing. OPENQASM can be used to describe general quantum computation based on circuit models, measurement-based models, and recent quantum computation experiments. Its nature makes it well suited for developers and researchers to explore and simulate quantum computing on a software platform that leads hardware.
QuTruk is a free, open-source, cross-platform quantum computing programming framework independently developed by the QS, and comprises a quantum programming API, quantum command translation, a quantum computing back-end interface and the like, and provides rich quantum algorithms and quantum application templates. Qualink also provides a visual editor that a user can build and run quantum circuits by dragging and configuring elements such as quantum gates, qubits, etc. The quantum programming framework of the QuTruk can be widely applied to the fields of quantum communication, quantum cryptography, quantum simulation, quantum chemistry and the like.
As shown in fig. 5, an architecture schematic diagram of the start quantum cloud platform is given. The Kernel quantum cloud platform comprises a front end, a service layer and a calculation layer. As shown in fig. 6, a schematic diagram of creating quantum wire code based on a visual programming tool is presented. Various quantum logic gate visual programming modules (compomers) are presented in fig. 6 for providing a user with the ability to drag programming to generate quantum wires. The visual editing process comprises the following steps: opening the front page of the Ke quantum cloud platform, wherein the page provides various door controls, and a user can edit an electronic circuit and configure a quantum door by clicking and dragging the controls. The user can drag the required quantum logic gate to the corresponding quantum bit (qr 0, qr 1, qr 2), and arrange the quantum logic gates on the quantum bit in time sequence, finally forming the quantum circuit.
The quantum circuit shown in fig. 6 sequentially performs the following quantum logic gates from 1 to 10 in time sequence.
1 Z * qr[0]
2 Y * qr[1]
3 X * qr[2]
4 Z * qr[0]
5 CRx(pi/2) * (qr[1], qr[0])
6 CRy(pi/2) * (qr[2], qr[0])
7 Measure * qr[0]
8 Measure * qr[1]
9 S * qr[2]
10 Measure * qr[2]
The quantum circuit shown in fig. 6 performs quantum logic gates in the order of 1 to 10 described above, performing a series of operations for each qubit. First the Z gate is performed on the 0 th qubit (corresponding to the Pauli-Z operation), then the Y gate is performed on the 1 st qubit (corresponding to the Pauli-Y operation), and finally the X gate is performed on the 2 nd qubit (corresponding to the Pauli-X operation). The Z gate is then performed again on the 0 th qubit. Then, the control rotation gate CRx (pi/2) (i.e., rotation gate rotated by pi/2 angle) is performed for the 1 st and 0 th qubits, and then the control rotation gate CRy (pi/2) is performed for the 2 nd and 0 th qubits. Next, a measurement operation (Measure) is performed on the 0 th and 1 st qubits, and a state preparation operation (S) is performed on the 2 nd qubit.
The translation process of the quantum computing program is demonstrated below taking the code of the program generated by the QuTrunk programming framework of the quantum cloud platform of the quantum of the opening family as an example to translate to the OPENQASM2.0 programming framework of the IBM quantum cloud platform. Example codes are as follows:
from qutrunk.circuit.gates import *
from qutrunk.circuit import QCircuit
from math import pi
class MyQCircuit(QCircuit):
def my_openqasm(self):
d = [
"OPENQASM 2.0",
'include "qelib1.inc"',
f"qreg q[{str(len(self.qreg))}]",
f"creg c[{str(len(self.qreg))}]",
]
for c in self.cmds:
d.append(c.qasm())
a = ";\n".join(d) + ";\n"
return a
qubit = 3
qc = MyQCircuit()
qr = qc.allocate(qubit)
cmd = qc.cmds
qasmdef = qc.my_openqasm().split(';\n')[4:]
print(qasmdef)
the code operation results are as follows:
['z q[0]', 'y q[1]', 'x q[2]', 'z q[0]', 'crx(1.5707963267948966) q[1],q[0]', 'cry(1.5707963267948966) q[2],q[0]', 'measure q[0] -> c[0]', 'measure q[1] -> c[1]', 's q[2]', 'measure q[2] -> c[2]', '']
in the above code example, first, a class named myqccircuit is defined, which inherits from qccircuit, and implements a method my_openqasm () for converting a quantum circuit based on QuTrunk into an instruction sequence conforming to the OPENQASM2.0 standard. The variable qubit in the code is assigned 3, indicating that 3 qubits (qubits) are used in the quantum circuit. Then an instance qc of myqccircuit is created and assigned the 3 qubits described above using the allocate method. Finally, the quantum circuit is converted into an instruction sequence conforming to OPENQASM2.0 standard by calling a my_openqasm () method, and the result is printed.
The purpose of this code section is to demonstrate how quantum circuit analog codes are written using Python and to convert QuTrunk-based quantum circuits into instruction sequences of the OPENQASM standard. And when the front end of the quantum cloud platform of the quantum in the opening department receives the quantum circuit program code generated by the user based on the Quantum code, the generated quantum circuit code is transmitted to the rear end of the quantum cloud platform of the quantum in the opening department. The back end converts the quantum wire into an instruction of the OPENQASM2.0 standard through the QuTruk.
As shown in fig. 7, a flow chart of quantum computing task execution is presented.

Quantum computing circuitry quantum computing resources that may be selected include quantum simulators or quantum computers.
The quantum computing task may be selectively performed at a local quantum cloud platform or a target quantum cloud platform. The target quantum cloud platform may be, for example, a third party quantum cloud platform such as the google quantum cloud platform, microsoft quantum cloud platform, hundred degree quantum cloud platform.
If quantum computing resources of the target quantum cloud platform are selected to be utilized to execute the quantum computing tasks, the user authority and an API interface of the target quantum cloud platform can be utilized to send the quantum computing tasks to the target quantum cloud platform. Before quantum computing tasks are generated, the quantum computing circuit needs to be translated into a quantum computing circuit conforming to the quantum programming framework standard of the target quantum cloud platform. And the target quantum cloud platform executes quantum computing tasks by using the selected quantum computing resources, and generates quantum computing task execution results after task execution is finished.
The local quantum cloud platform queries the target quantum cloud platform by using the user permission and the API interface to obtain a quantum computing task execution result, feeds the quantum computing task execution result back to the client, and allows the user to check the quantum computing task execution result through the client.
The information of the quantum computing task includes: task name, task ID, creation time, quantum computing resource, and may also include task source, resource provider, and execution times.
The result information of the quantum computing task includes: task name, task ID, creation time, execution times, end time, execution state, running time, quantum computing resources, task line codes, probability statistics, and may also include task sources, resource providers.

In fig. 9, a user inputs a quantum circuit to be calculated, judges whether a first quantum cloud platform has configured a user key of a third party quantum cloud platform serving as a second quantum cloud platform, if the key has been configured, displays all available quantum computing resources of the first quantum cloud platform and the third party quantum cloud platform to the user, and if the key has not been configured, displays only the quantum computing resources provided by the first quantum cloud platform. The user selects a quantum computing resource from available quantum computing resources for a quantum computing circuit, generates a quantum computing task and sends the quantum computing task to a quantum cloud platform to which the selected quantum computing resource belongs, and after the quantum computing task is executed, an execution result is obtained. And the first quantum cloud platform displays the quantum computing task execution result to the user.
