Single photon production by rephased amplified spontaneous emission
Robin N Stevenson, Michael R Hush, Andre R R Carvalho +3
The production of single photons using rephased amplified spontaneous emission is examined. This process produces single photons on demand with high efficiency by detecting the spo…
Systematic errors in current quantum state tomography tools
Christian Schwemmer, Lukas Knips, Daniel Richart +4
Common tools for obtaining physical density matrices in experimental quantum state tomography are shown here to cause systematic errors. For example, using maximum likelihood or le…
Laser Theory for Optomechanics: Limit Cycles in the Quantum Regime
Niels Lörch, Jiang Qian, Aashish Clerk +2
Optomechanical systems can exhibit self-sustained limit cycles where the quantum state of the mechanical resonator possesses nonclassical characteristics such as a strongly negativ…
The role of the probability current for time measurements
Nicola Vona, Detlef Dürr
Time measurements are routinely preformed in laboratories, nevertheless their theoretical account presents some difficulties and for actual experiments an approximate, semiclassica…
Multi-Time Equations, Classical and Quantum
Sören Petrat, Roderich Tumulka
Multi-time equations are evolution equations involving several time variables, one for each particle. Such equations have been considered for the purpose of making theories manifes…
Multi-Time Wave Functions for Quantum Field Theory
Sören Petrat, Roderich Tumulka
Multi-time wave functions such as have one time variable for each particle. This type of wave function arises as a relativistic generalization of…
Tapered fiber coupling of single photons emitted by a deterministically positioned single nitrogen vacancy center
Lars Liebermeister, Fabian Petersen, Asmus v. Münchow +11
A diamond nano-crystal hosting a single nitrogen vacancy (NV) center is optically selected with a confocal scanning microscope and positioned deterministically onto the subwaveleng…
Optimized state independent entanglement detection based on geometrical threshold criterion
Wieslaw Laskowski, Christian Schwemmer, Daniel Richart +3
Experimental procedures are presented for the rapid detection of entanglement of unknown arbitrary quantum states. The methods are based on the entanglement criterion using accessi…
Multi-Time Schrödinger Equations Cannot Contain Interaction Potentials
Sören Petrat, Roderich Tumulka
Multi-time wave functions are wave functions that have a time variable for every particle, such as . They arise as a relativistic analog of the wave func…
What does one measure, when one measures the arrival times of a quantum particle?
Nicola Vona, Günter Hinrichs, Detlef Dürr
What is the right statistics for the measurements of arrival times of a quantum particle? Although this question is very old, it is still open. Usual experiments are performed in f…
Can Bohmian mechanics be made relativistic?
Detlef Dürr, Sheldon Goldstein, Travis Norsen +2
In relativistic space-time, Bohmian theories can be formulated by introducing a privileged foliation of space-time. The introduction of such a foliation - as extra absolute space-t…
Domain-wall melting in ultracold boson systems with holes and spin-flip defects
Jad C. Halimeh, Anton Wöllert, Ian P. McCulloch +2
Quantum magnetism is a fundamental phenomenon of nature. As of late, it has garnered a lot of interest because experiments with ultracold atomic gases in optical lattices could be…
Scaling laws of the cavity enhancement for nitrogen-vacancy centers in diamond
Hanno Kaupp, Christian Deutsch, Huan-Cheng Chang +3
We employ a fiber-based optical microcavity with high finesse to study the enhancement of phonon sideband fluorescence of nitrogen-vacancy centers in nanodiamonds. Harnessing the f…
Device-independent demonstration of genuine multipartite entanglement
Julio T. Barreiro, Jean-Daniel Bancal, Philipp Schindler +5
Entanglement in a quantum system can be demonstrated experimentally by performing the measurements prescribed by an appropriate entanglement witness. However, the unavoidable misma…
On the uniqueness of the equation for state-vector collapse
A. Bassi, D. Duerr, G. Hinrichs
The linearity of quantum mechanics leads, under the assumption that the wave function offers a complete description of reality, to grotesque situations famously known as Schroeding…
Violation of Bell's inequalities with pre-amplified homodyne detection
G. Torlai, G. McKeown, P. Marek +4
We show that the use of probabilistic noiseless amplification in entangled coherent state-based schemes for the test of quantum non locality provides substantial advantages. The th…
Precise evaluation of thermal response functions by optimized density matrix renormalization group schemes
Thomas Barthel
This paper provides a study and discussion of earlier as well as novel more efficient schemes for the precise evaluation of finite-temperature response functions of strongly correl…
