Quantum wave packet revivals [PDF]
Physics Reports, 2004 The numerical prediction, theoretical analysis, and experimental verification of the phenomenon of wave packet revivals in quantum systems has flourished over the last decade and a half. Quantum revivals are characterized by initially localized quantum states which have a short-term, quasi-classical time evolution, which then can spread significantly ...

New Journal of Physics, 2022 High-efficiency photon-pair production is a long-sought-after goal for many optical quantum technologies, and coherent photon conversion (CPC) processes are promising candidates for achieving this. We show theoretically how to control coherent conversion

Quantum revivals and carpets in some exactly solvable systems [PDF]
, 1999 We consider the revival properties of quantum systems with an eigenspectrum E_{n} proportional to n^{2}, and compare them with the simplest member of this class - the infinite square well.

Fisher information, nonclassicality and quantum revivals [PDF]
Physics Letters A, 2013 Wave packet revivals and fractional revivals are studied by means of a measure of nonclassicality based on the Fisher information. In particular, we show that the spreading and the regeneration of initially Gaussian wave packets in a quantum bouncer and an in the infinite square-well correspond, respectively, to high and low nonclassicality values ...

About Quantum Revivals, Quantum Fidelity, A semiclassical Approach [PDF]
Journal of Physics A: Mathematical and General, 2004 In this paper we develop the topics of Quantum Recurrences and of Quantum Fidelity which have attracted great interest in recent years. The return probability is given by the square modulus of the overlap between a given initial wavepacket and the corresponding evolved one; quantum recurrences in time can be observed if this overlap is unity.

Prisoners’ Dilemma in a Spatially Separated System Based on Spin–Photon Interactions
Photonics, 2022 Having access to ideal quantum mechanical resources, the prisoners’ dilemma can be ceased. Here, we propose a distributed quantum circuit to allow spatially separated prisoners to play the prisoners’ dilemma game.
