Silicon spin qubits satisfy the necessary criteria for quantum information processing.
However, a demonstration of high-fidelity state preparation and readout combined with high …

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 …

We present a comprehensive architectural analysis for a proposed fault-tolerant quantum
computer based on cat codes concatenated with outer quantum error-correcting codes. For …

We report on the realization of a fast, scalable, and high-fidelity qubit architecture, based on
Yb 171 atoms in an optical tweezer array. We demonstrate several attractive properties of …

We propose and demonstrate an architecture for fluxonium-fluxonium two-qubit gates
mediated by transmon couplers (FTF, for fluxonium-transmon-fluxonium). Relative to …

Quantum many-body systems away from equilibrium host a rich variety of exotic phenomena
that are forbidden by equilibrium thermodynamics. A prominent example is that of discrete …

Superconducting qubits provide a promising path toward building large-scale quantum
computers. The simple and robust transmon qubit has been the leading platform, achieving …
