Medium-scale quantum devices that integrate about hundreds of physical qubits are likely to
be developed in the near future. However, these devices will lack the resources for realizing …

Superconducting qubits are leading candidates in the race to build a quantum computer
capable of realizing computations beyond the reach of modern supercomputers. The …

Quantum computing can become scalable through error correction, but logical error rates
only decrease with system size when physical errors are sufficiently uncorrelated. During …

Over the last two decades, tremendous advances have been made for constructing large-
scale quantum computers. In particular, quantum computing platforms based on …

The majority of quantum-error-detection and correction protocols assume that the population
in a qubit does not leak outside of its computational subspace. For many existing …
