Quantum-mechanical effects at the macroscopic level were first explored in Josephson-
junction-based superconducting circuits in the 1980s. In recent decades, the emergence of …

In the past 20 years, impressive progress has been made both experimentally and
theoretically in superconducting quantum circuits, which provide a platform for manipulating …

Decoherence in quantum computers is formulated within the semigroup approach. The error
generators are identified with the generators of a Lie algebra. This allows for a …

In the past year many developments have taken place in the area of quantum error
corrections. Recently Shor showed how to perform fault tolerant quantum computation …

The stable operation of quantum computers will rely on error correction, in which single
quantum bits of information are stored redundantly in the Hilbert space of a larger system …

Quantum information is vulnerable to environmental noise and experimental imperfections,
hindering the reliability of practical quantum information processors. Therefore, quantum …

We construct a new class of quantum error-correcting codes for a bosonic mode, which are
advantageous for applications in quantum memories, communication, and scalable …

In order to bring quantum networks into the real world, we would like to determine the
requirements of quantum network protocols including the underlying quantum hardware …

The early Gottesman, Kitaev, and Preskill (GKP) proposal for encoding a qubit in an
oscillator has recently been followed by cat-and binomial-code proposals. Numerically …

The development of robust architectures capable of large-scale fault-tolerant quantum
computation should consider both their quantum error-correcting codes and the underlying …
