Quantum information processing relies on the precise control of non-classical states in the
presence of many uncontrolled environmental degrees of freedom. The interactions …

Quantum decoherence plays a pivotal role in the dynamical description of the quantum-to-
classical transition and is the main impediment to the realization of devices for quantum …

The Jaynes–Cummings Model (JCM) has recently been receiving increased attention as
one of the simplest, yet intricately nonlinear, models of quantum physics. Emphasising the …

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

The realization of quantum error correction is an essential ingredient for reaching the full
potential of fault-tolerant universal quantum computation. Using a range of different …

The competition between scrambling unitary evolution and projective measurements leads
to a phase transition in the dynamics of quantum entanglement. Here, we demonstrate that …

Superconducting circuits are a competitive platform for quantum computation because they
offer controllability, long coherence times and strong interactions—properties that are …

Detecting single–photon level signals—carriers of both classical and quantum information—
is particularly challenging for low-energy microwave frequency excitations. Here we …

Heat engines convert thermal energy into mechanical work and generally involve a large
number of particles. We report the experimental realization of a single-atom heat engine. An …

We discuss a general method for constructing nonreciprocal, cavity-based photonic devices,
based on matching a given coherent interaction with its corresponding dissipative …
