论文摘要
我们引入了一个错误缓解框架，该框架使用电路切割来减轻量子电路中的错误。我们的框架可以在多项式时间内实现，以实现各种量子电路。我们的技术涉及切割电路的方式，使我们运行需要在量子硬件上执行的电路，而误差缓解电路则在模拟器上运行。我们通过QUBIT执行错误缓解QUBIT，然后提供一种方法来组合每个单个量子错误缓解措施运行的不同概率，以便减轻整个电路。我们将框架应用于VQE硬件有效的ANSATZ ANSATZ ANSATZ估计的基态能量，非常接近无噪声的模拟结果。
We introduce an error mitigation framework that mitigates errors in a quantum circuit using circuit cutting. Our framework can be implemented in polynomial time for a wide variety of quantum circuits. Our technique involves cutting the circuit in such a way that we run the circuit that needs to be executed on the quantum hardware whereas the error mitigation circuit is run on a simulator. We perform error mitigation qubit by qubit and then provide a way to combine the different probabilities from each of the individual qubit error mitigation runs such that the full circuit is error mitigated. We apply our framework to the VQE hardware-efficient ansatz acheiving estimated ground state energies very close to the noise-free simulation results.
