[0056] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0057] Example 1

[0058] refer to Figure 1 The diagram illustrates a flowchart of a quantum program compilation method disclosed in an embodiment of the present invention. In this embodiment, the method includes:

[0059] S101: Convert the multi-control bit quantum logic gate in the quantum program to be optimized into a first target logic gate to obtain a first quantum program; the first target logic gate is a logic gate that matches the target quantum platform, and the target quantum platform includes multiple quantum platforms;

[0060] In this embodiment, the quantum program uses multi-control bit quantum logic gates that are not supported by the quantum platform. In order to be applicable to the quantum platform, it needs to be converted into logic gates that the quantum platform can support. Different quantum platforms support different logic gates. In order for the quantum program to support multiple quantum platforms, it can be converted into different logic gates supported by different quantum platforms.

[0061] Optionally, to obtain support from different quantum platforms, in this embodiment, the multi-control bit quantum gate can be converted using the following method:

[0062] The two gates in the quantum program to be optimized are converted into a first combination of a single gate, a CNOT (Controlled-NOT) gate, and a CU gate;

[0063] The multi-control gates in the quantum program to be optimized are converted into a second combination of single gates, CNOT gates, and CU gates;

[0064] Convert the CU gate into a combination of a single gate and a CNOT gate;

[0065] Convert the single door into a first combination of U3 door and CZ door;

[0066] The CNOT gate is converted into a second combination of a U3 gate and a CZ gate.

[0067] Wherein, the CZ gate is the controlled-Z gate, and its corresponding matrix representation is:

[0068]

[0069] Among them, the CU gate is the control U gate, for example Figure 4 A schematic diagram of controlling the U-gate is shown.

[0070] The definition matrix of the U3 gate is as follows:

[0071] For example, a U3 gate is represented as:

[0072] In the U3 gate, the definable parameter is θ. λ.

[0073] In this embodiment, the quantum program to be optimized may contain some dual-gate and multi-controllable gates that are not supported by the quantum platform. The dual-gate and multi-controllable gates are converted into corresponding combinations of single-gate, CNOT gate, and CU gate. After conversion, the quantum program will contain single-gate, CNOT gate, and CU gate. To adapt to various different quantum platforms, CU gates also need to be converted into combinations of single-gate and CNOT gates, single gates into combinations of U3 gates and CZ gates, and CNOT gates into combinations of U3 gates and CZ gates. In one implementation, the first quantum logic gate can be represented as a U3 gate and a CZ gate, and multi-controllable bit quantum logic gates (dual-gate or multi-controllable gates) can be converted into U3 gates and CZ gates.

[0074] In this embodiment, the first combination of converting a dual-gate to a single-gate, a CNOT (Controlled-NOT) gate, and a CU gate, and the second combination of a single-gate, a CNOT gate, and a CU gate can be different. Similarly, the first combination of a U3 gate and a CZ gate and the second combination of a U3 gate and a CZ gate can also be different. S102: Optimize the quantum circuitry in the first quantum program to obtain the second quantum program;

[0075] Currently, quantum programs generally suffer from the problem of deep quantum circuitry. Existing compilation tools are unable to eliminate this problem, resulting in low execution efficiency of quantum algorithms and significant overhead in quantum simulation experiments or actual operation.

[0076] To address the aforementioned issues, the quantum circuitry in the quantum program was optimized in this embodiment.

[0077] The first quantum program is obtained by transforming the logic gates of the quantum program to be optimized. The optimization of the quantum circuits in the first quantum program includes the following two implementation methods:

[0078] Implementation Method 1:

[0079] Detect whether there is a first quantum circuit in the first quantum program that does not meet the preset depth requirements;

[0080] Identify a target quantum circuit that matches the first quantum circuit;

[0081] Replace the first quantum circuit with the target quantum circuit.

[0082] In this embodiment, a replacement rule base is pre-set, which stores the correspondence between the first quantum circuit to be replaced and the target quantum circuit. The first quantum circuit is a quantum circuit with higher depth, and the target quantum circuit is a quantum circuit with lower depth.

[0083] Those that do not meet the preset depth requirements can be understood as having a higher depth. Specifically, the degree of depth can be determined according to specific needs, and the preset depth requirements can also be confirmed according to specific needs.

[0084] Implementation Method Two:

[0085] Traverse the quantum circuits in the first quantum program to detect whether there are consecutive single gates or consecutive rotating gates;

[0086] If a series of consecutive single gates are detected, and the series of single gates meet a preset cancellation condition, then the series of single gates in the first quantum program are deleted.

[0087] If a series of revolving doors are detected and the series of revolving doors meet a preset merging condition, the series of revolving doors are merged into a target revolving door that matches the series of revolving doors.

[0088] In this embodiment, after the execution of consecutive single gates in the quantum program, it may represent a no-operation, that is, the result before the execution of consecutive single gates is the same as the result after the execution of consecutive single gates. In order to avoid invalid operations, in this embodiment, single gates that meet the preset cancellation conditions are deleted.

[0089] In this embodiment, the functions implemented by multiple rotating gates in the quantum program may be the same as the functions of a single rotating gate. Therefore, in order to save resources and improve efficiency, multiple consecutive rotating gates can be replaced with a single rotating gate. In a preset rule base, a correspondence between multiple consecutive rotating gates and their corresponding target rotating gates is pre-set. When consecutive rotating gates are detected, the corresponding target rotating gate is found from the preset rule base, and the consecutive rotating gates are replaced by the target rotating gate.

[0090] In this embodiment, only one of the above-mentioned implementation methods 1 and 2 can be executed, or both can be executed. When both implementation method 1 and implementation method 2 need to be executed, the execution order of implementation method 1 and implementation method 2 is not limited. Implementation method 1 can be executed first, and then implementation method 2 can be executed. In this case, the first quantum program in implementation method 2 is obtained after implementation method 1. Alternatively, implementation method 2 can be executed first, and then implementation method 1 can be executed. In this case, the first quantum program in implementation method 1 is obtained after implementation method 2.

[0091] S103: Replace the first logic gate in the second quantum program that does not meet the preset noise requirements with the second target logic gate to obtain the third quantum program;

[0092] In this embodiment, the current quantum program contains some logic gates with high noise levels, which reduces the execution accuracy of the algorithm. To improve the execution accuracy of the algorithm, this embodiment optimizes the quantum program and reduces the noise in the quantum program.

[0093] In this embodiment, by replacing the noisy logic gates in the quantum program with lower-noise target logic gates, the noise of the quantum program is reduced. In one implementation, S103 includes:

[0094] Traverse the second quantum program to detect whether there is a first logic gate that does not meet the noise requirements;

[0095] A second target logic gate that matches the first logic gate is determined from the preset replacement rules;

[0096] Replace the first logic gate with the second target logic gate.

[0097] In this embodiment, noise requirements are preset, and those that do not meet the noise requirements are considered to have high noise levels. A replacement rule base is also preset, which stores the correspondence between the first logic gate and the second target logic gate that do not meet the noise requirements.

[0098] S104: Determine a target compilation method that matches the target quantum platform from a variety of preset compilation methods, and compile the third quantum program using the target compilation method.

[0099] In this embodiment, in order to support different target quantum platforms, multiple compilation methods are set up. When compiling a quantum program, you only need to select the corresponding quantum compilation method.

[0100] In this embodiment, a correspondence between the target quantum platform and the compilation method is pre-set. Before compiling the quantum program, the target compilation method corresponding to the target quantum platform is determined, and the third quantum program is compiled using the target compilation method.

[0101] Optional compilation methods include: QASM-oriented code compilation methods and the compilation methods of Quil, a quantum instruction language developed by Rigetti, and the compilation methods of QRunes quantum instruction set launched by Origin Quantum. However, it should be noted that the preset compilation methods include, but are not limited to, QASM-oriented code compilation methods and QuinTengIR-oriented code compilation methods.

[0102] The QASM-oriented compilation method receives a third quantum program and outputs OpenQASM quantum assembly code. OpenQASM is one of the most widely used quantum computing assembly languages, similar to LIVMIR in classical computing. The multi-objective quantum code generation module allows the compilation of hybrid quantum programs written in high-level quantum programming languages ​​into OpenQASM quantum assembly, supporting a wider range of quantum machines.

Thus, by converting the quantum program into logic gates supported by multiple quantum platforms, a foundation is laid for compiling programs supported by multiple different quantum platforms. Furthermore, multiple compilation methods are pre-set, allowing selection of the desired compilation method, achieving the goal of supporting multiple quantum platforms, and optimizing the quantum program by reducing its depth and noise.
