The Wigner function was formulated in 1932 by Eugene Paul Wigner, at a time when
quantum mechanics was in its infancy. In doing so, he brought phase space representations …

Mechanical systems prepared in quantum non-Gaussian states constitute a new advanced
class of phenomena breaking the laws of classical physics. Specifically, such mechanical …

In recent years substantial efforts have been expended in extending thermodynamics to
single quantum systems. Quantum effects have emerged as a resource that can improve the …

Modulating the frequency of a harmonic oscillator at nearly twice its natural frequency leads
to amplification and self-oscillation. Above the oscillation threshold and in the presence of a …

The quantum Rabi model, involving a two-level system and a bosonic field mode, is
arguably the simplest and most fundamental model describing quantum light-matter …

In this article we develop a continuous variable (CV) shadow tomography scheme with wide
ranging applications in quantum optics. Our work is motivated by the increasing …

The quantum noise of the vacuum limits the achievable sensitivity of quantum sensors. In
non-classical measurement schemes the noise can be reduced to overcome this limitation …

We develop a deterministic method to generate and verify arbitrarily high NOON states of
quantized vibrations (phonons), through the coupling to the internal state. We experimentally …

We implement direct readout of the symmetric characteristic function of quantum states of the
motional oscillation of a trapped calcium ion. Suitably chosen internal state rotations …

Trapped atomic ion crystals are a leading platform for quantum simulations of spin systems,
with programmable and long-range spin-spin interactions mediated by excitations of …
