Simplified quantum process tomography
Webb27 maj 2011 · The operational quality of the QEC protocol can be assessed by exposing it to correctable errors, that is, single-qubit phase-flip errors. Ideally, the encoded qubit experiences an identity operation. Experimentally, the implemented process is characterized with quantum process tomography ( 22, 23 ), which yields a process … Webb27 apr. 2024 · Quantum process tomography (QPT) methods aim at identifying, i.e., estimating, a given quantum process.
