Classical and quantum-linearized descriptions of degenerate optomechanical parametric oscillators
Sebastian Pina-Otey, Fernando Jiménez, Peter Degenfeld-Schonburg +1
Recent advances in the development of modern quantum technologies have opened the possibility of studying the interplay between spontaneous parametric down-conversion and optomecha…
Visualizing operators of coupled spin systems
Ariane Garon, Robert Zeier, Steffen J. Glaser
The state of quantum systems, their energetics, and their time evolution is modeled by abstract operators. How can one visualize such operators for coupled spin systems? A general…
Protected gates for topological quantum field theories
Michael E. Beverland, Oliver Buerschaper, Robert Koenig +3
We study restrictions on locality-preserving unitary logical gates for topological quantum codes in two spatial dimensions. A locality-preserving operation is one which maps local…
Entangling the motion of two optically trapped objects via time-modulated driving fields
Mehdi Abdi, Michael J. Hartmann
We study entanglement of the motional degrees of freedom of two tethered and optically trapped microdisks inside a single cavity. By properly choosing the position of the trapped o…
Optimal control of the signal to noise ratio per unit time for a spin 1/2 particle
M. Lapert, E. Assémat, S. J. Glaser +1
We investigate the maximum signal to noise ratio per unit time that can be achieved for a spin 1/2 particle subjected to a periodic pulse sequence. Optimal control techniques are a…
Quantum channels with polytopic images and image additivity
Motohisa Fukuda, Ion Nechita, Michael M. Wolf
We study quantum channels with respect to their image, i.e., the image of the set of density operators under the action of the channel. We first characterize the set of quantum cha…
Two approaches to obtain the strong converse exponent of quantum hypothesis testing for general sequences of quantum states
Milán Mosonyi, Tomohiro Ogawa
We present two general approaches to obtain the strong converse rate of quantum hypothesis testing for correlated quantum states. One approach requires that the states satisfy a ce…
Positive reduction from spectra
Maria Anastasia Jivulescu, Nicolae Lupa, Ion Nechita +1
We study the problem of whether all bipartite quantum states having a prescribed spectrum remain positive under the reduction map applied to one subsystem. We provide necessary and…
Testing the Pauli Exclusion Principle for electrons at LNGS
H. Shi, S. Bartalucci, S. Bertolucci +27
High-precision experiments have been done to test the Pauli exclusion principle (PEP) for electrons by searching for anomalous -series X-rays from a Cu target supplied with elec…
Entangling two distant non-interacting microwave modes
M. Abdi, P. Tombesi, D. Vitali
We propose a protocol able to prepare two remote and initially uncorrelated microwave modes in an entangled stationary state, which is certifiable using only local optical homodyne…
Resource Cost Results for Entanglement Distillation and State Merging under Source Uncertainties
Holger Boche, Gisbert Janßen
We introduce one-way LOCC protocols for quantum state merging for compound sources, which have asymptotically optimal entanglement as well as classical communication resource costs…
Cooperative pulses in robust quantum control: Application to broadband Ramsey-type pulse sequence elements
Michael Braun, Steffen J. Glaser
A general approach is introduced for the efficient simultaneous optimization of pulses that compensate each other' s imperfections within the same scan. This is applied to broadban…
Steady-state phase diagram of a driven QED-cavity array with cross-Kerr nonlinearities
Jiasen Jin, Davide Rossini, Martin Leib +2
We study the properties of an array of QED-cavities coupled by nonlinear elements in the presence of photon leakage and driven by a coherent source. The main effect of the nonlinea…
Variations on Classical and Quantum Extractors
Mario Berta, Omar Fawzi, Volkher B. Scholz +1
Many constructions of randomness extractors are known to work in the presence of quantum side information, but there also exist extractors which do not [Gavinsky {\it et al.}, STOC…
Spontaneous, collective coherence in driven, dissipative cavity arrays
J. Ruiz-Rivas, E. del Valle, C. Gies +2
We study an array of dissipative tunnel-coupled cavities, each interacting with an incoherently pumped two-level emitter. For cavities in the lasing regime, we find correlations be…
Controlling Several Atoms in a Cavity
Michael Keyl, Robert Zeier, T. Schulte-Herbrueggen
We treat control of several two-level atoms interacting with one mode of the electromagnetic field in a cavity. This provides a useful model to study pertinent aspects of quantum c…
Cavity-enhanced room-temperature magnetometry using absorption by nitrogen-vacancy centers in diamond
K. Jensen, N. Leefer, A. Jarmola +5
We demonstrate a cavity-enhanced room-temperature magnetic field sensor based on nitrogen-vacancy centers in diamond. Magnetic resonance is detected using absorption of light reson…
Resource cost results for one-way entanglement distillation and state merging of compound and arbitrarily varying quantum sources
Holger Boche, Gisbert Janßen
We consider one-way quantum state merging and entanglement distillation under compound and arbitrarily varying source models. Regarding quantum compound sources, where the source i…
Positivity, Discontinuity, Finite Resources and Nonzero Error for Arbitrarily Varying Quantum Channels
H. Boche, J. Noetzel
This work is motivated by a quite general question: Under which circumstances are the capacities of information transmission systems continuous? The research is explicitly carried…
