Quantum computers hold the promise of solving computational problems that are intractable
using conventional methods. For fault-tolerant operation, quantum computers must correct …

Realizing the potential of quantum computing will require achieving sufficiently low logical
error rates. Many applications call for error rates in the $10^{-15} $ regime, but state-of-the …

Molecular nanomagnets (MNMs), molecules containing interacting spins, have been a
playground for quantum mechanics. They are characterized by many accessible low-energy …

Error correction is important in classical and quantum computation. Decoherence caused by
the inevitable interaction of quantum bits with their environment leads to dephasing or even …

The ability to detect and deal with errors when manipulating quantum systems is a
fundamental requirement for fault-tolerant quantum computing. Unlike classical bits that are …

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 …

Quantum computers could be used to solve certain problems exponentially faster than
classical computers, but are challenging to build because of their increased susceptibility to …

Realizing the potential of quantum computing requires sufficiently low logical error rates.
Many applications call for error rates as low as 10− 15 (refs.,,,,,,–), but state-of-the-art …

Quantum registers of nuclear spins coupled to electron spins of individual solid-state defects
are a promising platform for quantum information processing,,,,,,,,,,,,. Pioneering experiments …

Arbitrarily long quantum computations require quantum memories that can be repeatedly
measured without being corrupted. Here, we preserve the state of a quantum memory …
