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 …

Performing large calculations with a quantum computer will likely require a fault-tolerant
architecture based on quantum error-correcting codes. The challenge is to design practical …

Quantum error correction is an indispensable ingredient for scalable quantum computing. In
this Perspective we discuss a particular class of quantum codes called “quantum low-density …

Photonics is the platform of choice to build a modular, easy-to-network quantum computer
operating at room temperature. However, no concrete architecture has been presented so …

A bstract We review the properties of orbifold operations on two-dimensional quantum field
theories, either bosonic or fermionic, and describe the “Orbifold groupoids” which control the …

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

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

Error-corrected quantum computers can only work if errors are small and uncorrelated. Here,
I show how cosmic rays or stray background radiation affects superconducting qubits by …

Continuous-variable measurement-based quantum computation on cluster states has in
recent years shown great potential for scalable, universal, and fault-tolerant quantum …
