A single-atom heat engine
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 …

Quantum mechanics–free subsystem with mechanical oscillators
Quantum mechanics sets a limit for the precision of continuous measurement of the position
of an oscillator. We show how it is possible to measure an oscillator without quantum back …

Current fluctuations in open quantum systems: Bridging the gap between quantum continuous measurements and full counting statistics
Continuously measured quantum systems are characterized by an output current, in the form
of a stochastic and correlated time series, which conveys crucial information about the …

Reconciliation of quantum local master equations with thermodynamics
The study of open quantum systems often relies on approximate master equations derived
under the assumptions of weak coupling to the environment. However when the system is …

Beating the 3 db limit for intracavity squeezing and its application to nondemolition qubit readout
While the squeezing of a propagating field can, in principle, be made arbitrarily strong, the
cavity-field squeezing is subject to the well-known 3 dB limit, and thus has limited …
