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

Here, we report an experimental realization of multimode strong coupling in cavity quantum
electrodynamics. This novel regime is achieved when a single artificial atom is …

We point out that superconducting quantum computers are prospective for the simulation of
the dynamics of spin models far from equilibrium, including nonadiabatic phenomena and …

Precision sensing, and in particular high precision magnetometry, is a central goal of
research into quantum technologies. For magnetometers, often trade-offs exist between …

We present a proposal for a tunable source of single photons operating in the terahertz
(THz) regime. This scheme transforms incident visible photons into quantum THz radiation …

We experimentally investigate a strongly driven GaAs double quantum dot charge qubit
weakly coupled to a superconducting microwave resonator. The Floquet states emerging …

We have investigated the microwave response of a transmon qubit coupled directly to a
transmission line. In a transmon qubit, owing to its weak anharmonicity, a single driving field …

When optically pumped magnetometers are aimed for use in the Earth's magnetic field, the
orientation of the sensor to the field direction is of special importance to achieve accurate …

We propose a scheme of terahertz laser based on an ensemble of asymmetric quantum dots
dressed by an intense electromagnetic field. THz emission originates from the transitions at …

Strongly driving a two-level quantum system with light leads to a ladder of Floquet states
separated by the photon energy. Nanoscale quantum devices allow the interplay of confined …
