论文摘要
量子指令集（QIS）定义为通过控制量子硬件中的Qubits可以在物理上实现的量子门。在正确定义的QIS中将量子电路汇集到大门的乘积是量子计算的基本步骤。我们在这里提出了灵活设计的多量门门而形成的量子变异指令集（QUVIS），以提高量子计算的速度和准确性。使用精细粒度时间优化算法可以在Quvis中实现Quvis中实现门的控制。与标准QIS（例如量子微建筑集（QUMIS）（由几个单一和两倍的门（包括一个Qubit旋转）和受控的Not Gates）相比，在实现多个量子位和量子傅立叶变换的掉期时，证明了误差积累和时间成本的显着减少。对于量子硬件的需求相同，Quvis的时间成本减少到Qumis的一半不到一半。同时，随着编译电路的深度降低，误差会被抑制代数。作为具有高灵活性和效率的一般编译方法，可以为不同的量子电路定义Quvis，并适应具有不同交互的量子硬件。
The quantum instruction set (QIS) is defined as the quantum gates that are physically realizable by controlling the qubits in quantum hardware. Compiling quantum circuits into the product of the gates in a properly defined QIS is a fundamental step in quantum computing. We here propose the quantum variational instruction set (QuVIS) formed by flexibly designed multi-qubit gates for higher speed and accuracy of quantum computing. The controlling of qubits for realizing the gates in a QuVIS is variationally achieved using the fine-grained time optimization algorithm. Significant reductions in both the error accumulation and time cost are demonstrated in realizing the swaps of multiple qubits and quantum Fourier transformations, compared with the compiling by a standard QIS such as the quantum microinstruction set (QuMIS, formed by several one- and two-qubit gates including one-qubit rotations and controlled-NOT gates). With the same requirement on quantum hardware, the time cost for QuVIS is reduced to less than one half of that for QuMIS. Simultaneously, the error is suppressed algebraically as the depth of the compiled circuit is reduced. As a general compiling approach with high flexibility and efficiency, QuVIS can be defined for different quantum circuits and be adapted to the quantum hardware with different interactions.
