Phys. Rev. A 105, 032204 (2022) – Published 10 March 2022

Testing quantum mechanics against alternative theories must be done in a way that does not make assumptions about the validity of any particular theory, in particular, without presuming the correctness of quantum theory. Here, the authors set bounds on possible deviations from quantum theory using the formalism of Generalized Probabilistic Theories by experimentally probing a three-level system consisting of a photon shared among three modes. They find no evidence for the breakdown of quantum theory.

Phys. Rev. A 105, 032618 (2022) – Published 29 March 2022

The authors design and implement a laser system using novel phase modulation and highly dispersive element techniques for realizing high-fidelity control over atomic hyperfine states, which are useful as qubits in quantum information processing. This approach is demonstrated in a neutral 
87
Rb atomic system and could also be applied to trapped-ion systems.

The authors report a theoretical study on the process of stimulated Compton scattering in the close-to-threshold ionization of the hydrogen molecule with x-ray attosecond radiation by solving the time-dependent Schrödinger equation with nondipole corrections. They show how to control and isolate the nondipole-induced nonlinear photoelectron emission by adjusting the x-ray laser parameters and molecular alignment.

Studying out-of-equilibrium dynamics or quench dynamics in cold-atom systems has become a paradigm for studying phase transitions. In this paper, the authors experimentally study the relaxation dynamics of a trapped ultracold Bose gas cooled across the BEC threshold. They find, among other things, a delay in the onset of condensate formation depending on the collision rate of the gas and a universal condensate growth depending only on the cooling rate.

Modifying quantum optical states by zero-photon subtraction
C. M. Nunn, J. D. Franson, and T. B. Pittman
Phys. Rev. A 105, 033702 (2022) – Published 2 March 2022

The authors experimentally demonstrate that, counterintuitively, the heralding of zero photons in an ancillary mode can reduce the mean photon number in an optical mode despite the fact that no photons have been removed from the system. This scheme finds an immediate application in the process of noiseless attenuation.

Phys. Rev. A 105, 033714 (2022) – Published 23 March 2022

In an effort to better bridge quantum optics and strong-field physics, the authors demonstrate the ability of intense laser-atom interactions to generate coherent-state superpositions and tune their quantum properties. They show that these superpositions can transition from optical “cat” states to “kitten” states with a change in atomic density, and report the highest-photon-number optical cat state to date.

They show how to control and isolate the nondipole-induced nonlinear photoelectron emission by adjusting the x-ray laser parameters and molecular alignment.

Studying out-of-equilibrium dynamics or quench dynamics in cold-atom systems has become a paradigm for studying phase transitions. In this paper, the authors experimentally study the relaxation dynamics of a trapped ultracold Bose gas cooled across the BEC threshold. They find, among other things, a delay in the onset of condensate formation depending on the collision rate of the gas and a universal condensate growth depending only on the cooling rate.
