Control of interference and diffraction of a three-level atom in a double-slit scheme with cavity fields
(American Physical Society, 2020-09-28)
A double-cavity with a quantum mechanical and a classical field is placed immediately behind a double-slit in order to analyze the wave-particle duality. Both fields have common nodes and antinodes through which a three-level ...
Controlling parameters of the wave-particle duality of a two-level atom in a double-slit scheme with cavity field
(The Optical Society, 2021-01)
A double-slit scheme placed immediately before a standing wave allows one to establish two possible paths for the passage of an atom. Each path matches with a node or antinode of the wave. The atom–field interaction is ...
Ultra-high optical nonreciprocity with a coupled triple-resonator structure
(IOP Publishing Ltd., 2021)
Optical transmission nonreciprocity as a widely investigated phenomenon is essential to various applications. Many sophisticated mechanisms have been proposed and tested for achieving the optical nonreciprocity on integrated ...
Coherent population trapping with a controlled dissipation: applications in optical metrology
(IOP PUBLISHING LTD, 2018)
We analyze the properties of a pulsed coherent population trapping protocol that uses a controlled decay from the excited state in a Lambda-level scheme. We study this problem analytically and numerically and find regimes ...
Macroscopic nonclassical-state preparation via postselection
(American Physical Society, 2017)
Macroscopic quantum superposition states are fundamental to test the classical-quantum boundary and present suitable candidates for quantum technologies. Although the preparation of such states has already been realized, ...
Breaking the optomechanical cooling limit by two drive fields on a membrane-in-the-middle system
(AMER PHYSICAL SOC, 2019)
We present a theoretical scheme for ground-state cooling of a mechanical resonator in a membrane-in-themiddle optomechanical system (OMS) driven by two red-detuned drive fields. The details of dynamical evolution of OMS ...
Storage and retrieval of interacting photons in a Rydberg medium
(AMER PHYSICAL SOC, 2019)
Storing interacting photons in ensembles of highly excited Rydberg atoms makes it possible to realize photon-photon gates. The efficiency of stopping and retrieving pairs of single-photon pulses in any Rydberg medium is, ...
Highly efficient cooling of mechanical resonator with square pulse drives
(OPTICAL SOC AMER, 2018)
Ground state cooling of mechanical resonator is a way to generate macroscopic quantum states. Here we present a study of optomechanical cooling under the drive of square pulses without smooth profile. By illustrating the ...
Optimizing synthetic diamond samples for quantum sensing technologies by tuning the growth temperature
(ELSEVIER SCIENCE SA, 2019)
Control of the crystalline orientation of nitrogen-vacancy (NV) defects in diamond is here demonstrated by tuning the temperature of chemical vapor deposition (CVD) growth on a (113)-oriented diamond substrate. We show ...
Experimental quantum tomography assisted by multiply symmetric states in higher dimensions
(AMER PHYSICAL SOC, 2019)
High-dimensional quantum information processing has become a mature field of research with several different approaches being adopted for the encoding of D-dimensional quantum systems. Such progress has fueled the search ...
