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 …

Radio-frequency communication systems have long used bulk-and surface-acoustic-wave
devices supporting ultrasonic mechanical waves to manipulate and sense signals. These …

Many important phenomena in quantum devices are dynamic, meaning that they cannot be
studied using time-averaged measurements alone. Experiments that measure such transient …

We propose to directly and quantum-coherently couple a superconducting transmon qubit to
magnons—the quanta of the collective spin excitations, in a nearby magnetic particle. The …

A large spatial quantum superposition of size O (1–10) μ m for mass m∼ 10− 17–10− 14 kg
is required to probe the foundations of quantum mechanics and test the classical and …

Probing quantum mechanics and quantum aspects of general relativity, along with the
sensing and constraining of classical gravity, can all be enabled by unprecedented spatial …

The traditional view from particle physics is that quantum gravity effects should only become
detectable at extremely high energies and small length scales. Due to the significant …

Cavity-electromechanical systems are extensively used for sensing and controlling the
vibrations of mechanical resonators down to their quantum limit. The nonlinear radiation …

A pristine suspended carbon nanotube is a near ideal environment to host long-lived
quantum states. For this reason, they have been used as the core element of qubits and to …

We report an ingenious mechanism to obtain robust optical pulling force by a single plane
wave via engineering the topology of light momentum in the background. The underlying …
