Quantum error correction protocols will play a central role in the realisation of quantum
computing; the choice of error correction code will influence the full quantum computing …

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

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

For the first time in history, we are seeing a branching point in computing paradigms with the
emergence of quantum processing units (QPUs). Extracting the full potential of computation …

The accumulation of physical errors,–prevents the execution of large-scale algorithms in
current quantum computers. Quantum error correction promises a solution by encoding k …

We discuss invertible and non-invertible topological condensation defects arising from
gauging a discrete higher-form symmetry on a higher codimensional manifold in spacetime …

The standard primitives of quantum computing include deterministic unitary entangling
gates, which are not natural operations in many systems including photonics. Here, we …

Full-scale quantum computers require the integration of millions of qubits, and the potential
of using industrial semiconductor manufacturing to meet this need has driven the …

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 …
