Quantum mechanics is an extremely successful theory that agrees with every experimental
test. However, the principle of linear superposition, a central tenet of the theory, apparently …

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 …

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 …

It is control that turns scientific knowledge into useful technology: in physics and engineering
it provides a systematic way for driving a dynamical system from a given initial state into a …

We consider a quantum Otto cycle for a time-dependent harmonic oscillator coupled to a
squeezed thermal reservoir. We show that the efficiency at maximum power increases with …

Linear strings of trapped atomic ions held in radio-frequency (rf) traps constitute one of the
leading platforms for quantum simulation experiments, allowing the investigation of …

We propose an experimental scheme to realize a nanoheat engine with a single ion. An Otto
cycle may be implemented by confining the ion in a linear Paul trap with tapered geometry …

The availability of a universal quantum computer may have a fundamental impact on a vast
number of research fields and on society as a whole. An increasingly large scientific and …

Hybrid systems of laser-cooled trapped ions and ultracold atoms combined in a single
experimental setup have recently emerged as a new platform for fundamental research in …

Accurately controlling a quantum system is a fundamental requirement in quantum
information processing and the coherent manipulation of molecular systems. The ultimate …
