摘要：
量子信息处理的实验实现现在已经达到了量子过程层析成像不切实际的复杂程度。实验设置的数量以及数据后处理的计算成本现在转化为几天的努力来表征即使只有8个量子位的实验。最近提出了一种更实用的方法来确定实验量子过程的保真度，其中实验数据直接与使用Monte Carlo采样的理想过程进行比较。在这里，我们提出了一个实验实现这个方案的电路量子电动力学设置，以确定两个量子比特门，如cphase和cnot门，和三个量子比特门，如Toffoli门和两个连续的cphase门的保真度。
英文摘要：
Experimental implementations of quantum information processing have now reached a level of sophistication where quantum process tomography is impractical. The number of experimental settings as well as the computational cost of the data post-processing now translates to days of effort to characterize even experiments with as few as 8 qubits. Recently a more practical approach to determine the fidelity of an experimental quantum process has been proposed, where the experimental data is compared directly to an ideal process using Monte Carlo sampling. Here we present an experimental implementation of this scheme in a circuit quantum electrodynamics setup to determine the fidelity of two qubit gates, such as the cphase and the cnot gate, and three qubit gates, such as the Toffoli gate and two sequential cphase gates.
