A fault-tolerant honeycomb memory

C Gidney, M Newman, A Fowler, M Broughton - Quantum, 2021 - quantum-journal.org
Abstract Recently, Hastings & Haah introduced a quantum memory defined on the
honeycomb lattice. Remarkably, this honeycomb code assembles weight-six parity checks …

Characterizing midcircuit measurements on a superconducting qubit using gate set tomography

K Rudinger, GJ Ribeill, LCG Govia, M Ware… - Physical Review …, 2022 - APS
Measurements that occur within the internal layers of a quantum circuit—midcircuit
measurements—are a useful quantum-computing primitive, most notably for quantum error …

Qubit parity measurement by parametric driving in circuit QED

B Royer, S Puri, A Blais - Science advances, 2018 - science.org
Multiqubit parity measurements are essential to quantum error correction. Current
realizations of these measurements often rely on ancilla qubits, a method that is sensitive to …

Exceptional-point-engineered dispersive readout of a driven three-level atom weakly interacting with coupled cavities in non-Markovian environments

JF Yang, HZ Shen - Physical Review A, 2024 - APS
In this paper we study the dispersive readout of a driven three-level atom weakly interacting
with a passive cavity that couples to an active cavity. The system excluding the three-level …

Always-on quantum error tracking with continuous parity measurements

R Mohseninia, J Yang, I Siddiqi, AN Jordan… - Quantum, 2020 - quantum-journal.org
We investigate quantum error correction using continuous parity measurements to correct bit-
flip errors with the three-qubit code. Continuous monitoring of errors brings the benefit of a …
