一个噪声量子过程的互补经典操作表征

Characterization of a noisy quantum process by complementary classical operations

Holger F. Hofmann, Ryo Okamoto, Shigeki Takeuchi

摘要:

量子信息的挑战之一是在实验设备的操作中证明量子相干性。虽然全量子过程层析成像可以完成这项工作,但它既麻烦又不直观。在本演示文稿中,我们表明,一个令人惊讶的详细和直观的访问表征错误是可能的,通过测量的误差统计只有两个互补的经典操作的量子门。

英文摘要:

One of the challenges in quantum information is the demonstration of quantum coherence in the operations of experimental devices. While full quantum process tomography can do the job, it is both cumbersome and unintuitive. In this presentation, we show that a surprisingly detailed and intuitively accessible characterization of errors is possible by measuring the error statistics of only two complementary classical operations of a quantum gate.
