Dissipative Many-body Quantum Optics in Rydberg Media
Alexey V. Gorshkov, Rejish Nath, Thomas Pohl
We develop a theoretical framework for the dissipative propagation of quantized light in interacting optical media under conditions of electromagnetically induced transparency (EIT…
Manipulating energy and spin currents in nonequilibrium systems of interacting qubits
Vladislav Popkov, Roberto Livi
We consider generic interacting chain of qubits, which are coupled at the edges to baths of fixed polarizations. We can determine the nonequilibrium steady states, described by the…
Entangled Phase States via Quantum Beam Splitter
M. Daoud, E. B. Choubabi
We study the entanglement effect of beam splitter on the temporally stable phase states. Specifically, we consider the eigenstates (phase states) of an unitary phase operator resul…
Three dimensional quantum key distribution in the presence of several eavesdroppers
M. Daoud, H. Ez-zahraouy
Quantum key distribution based on encoding in three dimensional systems in the presence of several eavesdroppers is proposed. This extends the BB84 protocol in the presence of many…
Extended Weyl-Heisenberg algebra, phase operator, unitary depolarizers and generalized Bell states
M. Daoud, E. H. El Kinani
Finite dimensional representations of extended Weyl-Heisenberg algebra are studied both from mathematical and applied viewpoints. They are used to define unitary phase operator and…
Influence of boundary conditions on quantum escape
Orestis Georgiou, Goran Gligorić, Achilleas Lazarides +3
It has recently been established that quantum statistics can play a crucial role in quantum escape. Here we demonstrate that boundary conditions can be equally important - moreover…
On the alternatives for bath correlators and spectral densities from mixed quantum-classical simulations
Stéphanie Valleau, Alex Eisfeld, Alán Aspuru-Guzik
We investigate on the procedure of extracting a "spectral density" from mixed QM/MM calculations and employing it in open quantum systems models. In particular, we study the connec…
Avoided level crossings in open quantum systems
Hichem Eleuch, Ingrid Rotter
At high level density, two states avoid usually crossing at the critical value of the parameter by which the system is controlled. The wavefunctions of the two sta…
Dynamical stabilization and time in open quantum systems
Ingrid Rotter
The meaning of time in an open quantum system is considered under the assumption that both, system and environment, are quantum mechanical objects. The Hamilton operator of the sys…
Non-Markovian waiting time distribution
Kimmo Luoma, Kari Härkönen, Sabrina Maniscalco +2
Simulation methods based on stochastic realizations of state vector evolutions are commonly used tools to solve open quantum system dynamics, both in the Markovian and non-Markovia…
Tailoring many-body entanglement through local control
Felix Lucas, Florian Mintert, Andreas Buchleitner
We construct optimal time-local control pulses based on a multipartite entanglement measure as target functional. The underlying control Hamiltonians are derived in a purely algebr…
The quantum adiabatic algorithm and scaling of gaps at first order quantum phase transitions
C. R. Laumann, R. Moessner, A. Scardicchio +1
Motivated by the quantum adiabatic algorithm (QAA), we consider the scaling of the Hamiltonian gap at quantum first order transitions, generally expected to be exponentially small…
Huygens-Fresnel-Kirchhoff construction for quantum propagators with application to diffraction in space and time
Arseni Goussev
We address the phenomenon of diffraction of non-relativistic matter waves on openings in absorbing screens. To this end, we expand the full quantum propagator, connecting two point…
