Coherent transport of quantum states by deep reinforcement learning [PDF]
Communications Physics, 2019 Some problems in physics can be handled only after a suitable ansatz solution has been guessed, proving to be resilient to generalization. The coherent transport of a quantum state by adiabatic passage through an array of semiconductor quantum dots is an

Journal of Physics A: Mathematical and Theoretical, 2012 The aim of this paper is to give a self-contained and unified presentation of a fermionic coherent state theory with the necessary mathematical details, discussing their definition, properties and some applications. After defining Grassmann algebras, it is possible to get a classical analog for the fermionic degrees of freedom in a quantum system ...

Coherent absorption of N00N states [PDF]
Conference on Lasers and Electro-Optics, 2016 Recent results in deeply subwavelength thickness films demonstrated coherent control and logical gate operations with both classical and single photon light sources. However, quantum processing and devices typically involve more than one photon and non-trivial input quantum states.

Transcoherent States: Optical States for Maximal Generation of Atomic Coherence
PRX Quantum, 2020 Quantum technologies are built on the power of coherent superposition. Atomic coherence is typically generated from optical coherence, most often via Rabi oscillations.

DYNAMICS OF GENERALIZED COHERENT STATES [PDF]
Modern Physics Letters B, 1995 We show that generalized coherent states follow Schrödinger dynamics in time-dependent potentials. The normalized wave-packets follow a classical evolution without spreading; in turn, the Schrödinger potential depends on the state through the classical trajectory.

Stretched Coherent States [PDF]
, 2023 The fundamental properties of recently introduced stretched coherent states are investigated. It has been shown that stretched coherent states retain the fundamental properties of standard coherent states and generalize the resolution of unity, or ...

Generalized coherent states [PDF]
, 2016 In the coherent state of the harmonic oscillator, the probability density is that of the ground state subjected to an oscillation along a classical trajectory. Senitzky and others pointed out that there are states of the harmonic oscillator corresponding

Coherence measures and optimal conversion for coherent states [PDF]
Quantum information & computation, 2015 We discuss a general strategy to construct coherence measures. One can build an important class of coherence measures which cover the relative entropy measure for pure states, the l1-norm measure for pure states and the α-entropy measure.

Quantum key distribution using gaussian-modulated coherent states [PDF]
Nature, 2003 Quantum continuous variables are being explored as an alternative means to implement quantum key distribution, which is usually based on single photon counting.

Quantum test of the equivalence principle for atoms in coherent superposition of internal energy states [PDF]
Nature Communications, 2017 The Einstein equivalence principle (EEP) has a central role in the understanding of gravity and space–time. In its weak form, or weak equivalence principle (WEP), it directly implies equivalence between inertial and gravitational mass.
