We construct quantum error-correcting codes that embed a finite-dimensional code space in
the infinite-dimensional Hilbert space of rotational states of a rigid body. These codes, which …

Charged microparticles confined in electrodynamic traps evolve into strongly coupled
Coulomb systems (SCCS) which are the subject of current investigation. Recent results with …

Spatially-structured laser beams, eventually carrying orbital angular momentum, affect
electronic transitions of atoms and their motional states in a complex way. We present a …

Experimental proposals for testing quantum gravity-induced entanglement of masses
(QGEM) typically involve two interacting masses which are each in a spatial superposition …

Resource efficient schemes for the quantum simulation of lattice gauge theories can benefit
from hybrid encodings of gauge and matter fields that use the native degrees of freedom …

Levitating charged particles in ultrahigh vacuum provides a preeminent platform for quantum
information processing, for quantum-enhanced force and torque sensing, for probing …

A rich and powerful toolbox for individually trapped atomic ions is available for quantum
information processing, including quantum metrology and quantum simulation …

We address the problem of determining the physically correct definition of the momentum
and angular momentum densities in a spatially structured electromagnetic field, given that …

A mesoscopic system of a few particles can undergo changes of configuration that resemble
phase transitions but with a nonuniversal behavior. A notable example is orientational …

The quantum rotor is one of the simplest model systems in quantum mechanics, but only in
recent years has theoretical work revealed general fundamental scaling laws for its …
