Entanglement is a quintessential quantum mechanical phenomenon with no classical
equivalent. First discussed by Einstein, Podolsky, and Rosen and formally introduced by …

Bosonic modes have wide applications in various quantum technologies, such as optical
photons for quantum communication, magnons in spin ensembles for quantum information …

Quantum error correction is a critical technique for transitioning from noisy intermediate-
scale quantum devices to fully fledged quantum computers. The surface code, which has a …

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

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

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 …

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 …

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 …

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 …

Routing quantum information between non-local computational nodes is a foundation for
extensible networks of quantum processors. Quantum information transfer between arbitrary …
