Compound beams for direct experimental comparison of quantum operations
Kishore Thapliyal, Jan Perina, Pavel Pavlicek +1
Compound beams composed of simple experimental blocks (detected in simultaneous detection windows) that form specific quantum-correlated structures are suggested for simulating the…
Improving quantum-battery charging via unidirectional quantum jumps to metastable state
Ewelina Lange, Grzegorz Chimczak, Anna Kowalewska-Kudłaszyk +2
In the process of charging a quantum battery, quantum jumps play a detrimental role because they induce transitions from higher to lower energy levels, leading to energy dissipatio…
Multiple quantum exceptional, diabolical, and hybrid points in multimode bosonic systems: II. Nonconventional PT-symmetric dynamics and unidirectional coupling
Jan PeÅina, Kishore Thapliyal, Grzegorz Chimczak +2
We analyze the existence and degeneracies of quantum exceptional, diabolical, and hybrid points in simple bosonic systems - comprising up to six modes with damping and/or amplifica…
Multiple quantum exceptional, diabolical, and hybrid points in multimode bosonic systems: I. Inherited and genuine singularities
Kishore Thapliyal, Jan PeÅina, Grzegorz Chimczak +2
The existence and degeneracies of quantum exceptional, diabolical, and hybrid (i.e., diabolically degenerated exceptional) singularities of simple bosonic systems composed of up to…
Effects of Markovian noise and cavity disorders on the entanglement dynamics of double Jaynes-Cummings models
Harsh Rathee, Kishore Thapliyal, Anirban Pathak
The ability to prepare and manipulate non-classical states, such as entangled qubits, is fundamental to the development of quantum information processing, communication, and comput…
Probing quantum correlations in non-degenerate hyper-Raman process
Moumita Das, Biswajit Sen, Ankur Sensharma +2
Possibilities of observing single mode and intermodal quantum correlations (e.g., antibunching, steering and entanglement) are studied for a probed-hyper-Raman system with specific…
