Entropy production in open quantum systems: exactly solvable qubit models
V. G. Morozov, G. Röpke
We present analytical results for the time-dependent information entropy in exactly solvable two-state (qubit) models. The first model describes dephasing (decoherence) in a qubit…
Body-assisted dispersion potentials of diamagnetic atoms
Stefan Yoshi Buhmann, Hassan Safari, Stefan Scheel +1
We derive Casimir-Polder and van der Waals potentials of one or two atoms with diamagnetic properties in an arbitrary environment of magnetoelectric bodies. The calculations are ba…
Quasiprobabilities for Multipartite Quantum Correlations of Light
E. Agudelo, J. Sperling, W. Vogel
Regular quasiprobabilities are introduced for the aim of characterizing quantum correlations of multimode radiation fields. Negativities of these quantum-correlation quasiprobabili…
Casimir-Polder Forces between Chiral Objects
David T. Butcher, Stefan Yoshi Buhmann, Stefan Scheel
The chiral component of the Casimir-Polder potential is derived within the framework of macroscopic quantum electrodynamics. It is shown to exist only if the particle and the mediu…
Analytical progress on symmetric geometric discord: Measurement-based upper bounds
Adam Miranowicz, Pawel Horodecki, Ravindra W. Chhajlany +2
Quantum correlations may be measured by means of the distance of the state to the subclass of states having well defined classical properties. In particular, a geometric measur…
Complete nonclassicality test with a photon-number resolving detector
T. Kiesel, W. Vogel
We present a method for the experimental measurement of nonclassicality witnesses and demonstrate its application. Our proposal only requires the coherent displacement of the initi…
Strongly entangled light from planar microcavities
D. Pagel, H. Fehske, J. Sperling +1
The emission of entangled light from planar semiconductor microcavities is studied and the entanglement properties are analyzed and quantified. Phase-matching of the intra-cavity s…
Atomic nonclassicality quasiprobabilities
T. Kiesel, W. Vogel, S. L. Christensen +3
Although nonclassical quantum states are important both conceptually and as a resource for quantum technology, it is often difficult to test whether a given quantum system displays…
Optimal Squeezing in Resonance Fluorescence via Atomic-State Purification
P. Grünwald, W. Vogel
Squeezing of atomic resonance fluorescence is shown to be optimized by a properly designed environment, which can be realized by a quasi-resonant cavity. Optimal squeezing is achie…
Multipartite minimum uncertainty products
E. Shchukin
In our previous work we have found a lower bound for the multipartite uncertainty product of the position and momentum observables over all separable states. In this work we are tr…
Universal nonclassicality witnesses for harmonic oscillators
T. Kiesel, W. Vogel
It is shown that a nonclassicality witness, whose expectation value can be measured for all quantum states, can be constructed from every nonclassicality filter. This finding leads…
Second order coupling between excited atoms and surface polaritons
Sofia Ribeiro, Stefan Y. Buhmann, Stefan Scheel
Casimir-Polder interactions between an atom and a macroscopic body are typically regarded as due to the exchange of virtual photons. This is strictly true only at zero temperature.…
Entanglement quasiprobabilities of squeezed light
J. Sperling, W. Vogel
We demonstrate the feasibility to completely characterize entanglement by negativities of quasiprobabilities. This requires the complete solution of a sophisticated mathematical pr…
Sub-binomial light
J. Sperling, W. Vogel, G. S. Agarwal
The click statistics from on-off detector systems is quite different from the counting statistics of the more traditional detectors. This necessitates introduction of new parameter…
Laser Control of Dissipative Two-Exciton Dynamics in Molecular Aggregates
Yun-an Yan, Oliver Kühn
There are two types of two-photon transitions in molecular aggregates, that is, non-local excitations of two monomers and local double excitations to some higher excited intra-mono…
True photo-counting statistics of multiple on-off detectors
J. Sperling, W. Vogel, G. S. Agarwal
We derive a closed photo-counting formula, including noise counts and a finite quantum efficiency, for photon number resolving detectors based on on-off detectors. It applies to de…
Moments of nonclassicality quasiprobabilities
Saleh Rahimi-Keshari, Thomas Kiesel, Werner Vogel
A method is introduced for the verification of nonclassicality in terms of moments of nonclassicality quasiprobability distributions. The latter are easily obtained from experiment…
