摘要

量子过程层析成像允许完整和精确的表征量子操作。我们报告了使用单量子位、最大纠缠和非纠缠输入状态的单一、退相干和部分极化操作的量子过程层析成像。

Single-qubit, entanglement-assisted and ancilla-assisted quantum process tomography
Quantum process tomography allows complete and precise characterization of a quantum operation. We report quantum process tomography of unitary, decohering, and partially polarizing operations using single-qubit, maximally entangled, and non-entangled input states.
