Here, we demonstrate the implementation of Pauli-frame randomization in a superconducting circuit system, exploiting a flexible programming and control infrastructure to achieve this with low effort.
Quantum error correction (QEC) is used in quantum computing to protect quantum information from errors due to decoherence and other quantum noise. Quantum error correction is theorised as essential to achieve fault tolerant quantum computing that can reduce the effects of noise on stored quantum information, faulty quantum gates, faulty quantum preparation, and faulty measurements. This would allow algorithms of greater circuit depth. WebDec 20, 2024 · We now examine the logical time to failure of the encoded qubit. As a failure metric we use the diamond norm and also the worst-case infidelity [], since the latter naturally arises in a simulation of the time evolution.We show that both metrics give the same result for the failure time.
