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

During the last ten years, superconducting circuits have passed from being interesting
physical devices to becoming contenders for near-future useful and scalable quantum …

Hybrid quantum circuits combine two or more physical systems, with the goal of harnessing
the advantages and strengths of the different systems in order to better explore new …

We report the realization of a quantum circuit in which an ensemble of electronic spins is
coupled to a frequency tunable superconducting resonator. The spins are nitrogen-vacancy …

The ability to generate particles from the quantum vacuum is one of the most profound
consequences of Heisenberg's uncertainty principle. Although the significance of vacuum …

Quantum emitters respond to resonant illumination by radiating part of the absorbed energy.
A component of this radiation field is phase coherent with the driving tone, whereas another …

We have developed a new superconducting digital technology, Reciprocal Quantum Logic,
that uses ac power carried on a transmission line, which also serves as a clock. Using …

We report the experimental realization of a hybrid quantum circuit combining a
superconducting qubit and an ensemble of electronic spins. The qubit, of the transmon type …

We discuss prospects of building hybrid quantum devices involving elements of atomic and
molecular physics, quantum optics and solid-state elements with the attempt to combine …

We investigate the dynamical Casimir effect in a coplanar waveguide (CPW) terminated by a
superconducting quantum interference device (SQUID). Changing the magnetic flux through …
