Transforming stand-alone qubits into a functional, general-purpose quantum processing unit
requires an architecture where many-body quantum entanglement can be generated and …

Currently available quantum processors are dominated by noise, which severely limits their
applicability and motivates the search for new physical qubit encodings. In this work, we …

We demonstrate strong dispersive coupling between a fluxonium superconducting qubit and
a 690 megahertz mechanical oscillator, extending the reach of circuit quantum acousto …

In a quantum processor, the device design and external controls together contribute to the
quality of the target quantum operations. As we continuously seek better alternative qubit …

Quantum computing systems require methods to control energies of qubits and couplers for
quantum operations. Flux biasing of qubits and quantum couplers is provided for a …

Superconducting circuit is a promising platform for quantum computing and quantum
simulation. A number of efforts have been made to explore the physics in transmon systems …

Quantum information is fragile, and the physical systems we use to protect it are often
complex. Even with rapid advances in superconducting circuits over the past two decades …
