Quantum interference enables constant-time quantum information processing
M. Stobińska, A. Buraczewski, M. Moore +8
It is an open question how fast information processing can be performed and whether quantum effects can speed up the best existing solutions. Signal extraction, analysis and compre…
Quantum steering inequality with tolerance for measurement-setting-errors: experimentally feasible signature of unbounded violation
Adam Rutkowski, Adam Buraczewski, Paweł Horodecki +1
Quantum steering is a relatively simple test for quantumness of correlations, proving that the values of quantum-mechanical measurement outcomes come into being only in the act of…
Two Copies of the Einstein-Podolsky-Rosen State of Light Lead to Refutation of EPR Ideas
Krzysztof Rosołek, Magdalena Stobińska, Marcin Wieśniak +1
Bell's theorem applies to the normalizable approximations of the original Einstein-Podolsky-Rosen (EPR) state. The constructions of the proof require measurements difficult to perf…
Multi-photon quantum interference with high visibility using multiport beam splitters
M. Stobińska, W. Laskowski, M. Wieśniak +1
Multi-photon states can be produced in multiple parametric down conversion (PDC) processes. The nonlinear crystal in such a case is pumped with high power. In theory, the more popu…
Exploring Macroscopic Entanglement with a Single Photon and Coherent States
Pavel Sekatski, Nicolas Sangouard, Magdalena Stobinska +3
Entanglement between macroscopically populated states can easily be created by combining a single photon and a bright coherent state on a beam-splitter. Motivated by the simplicity…
Single-photon single-ion interaction in free space configuration in front of a parabolic mirror
Magdalena Stobińska, Robert Alicki
The efficient interaction between single photons and single matter objects in free space is of key importance for quantum technologies. An experimental setup for testing this possi…
The standard fair sampling assumption is not necessary to test local realism
Dominic W. Berry, Hyunseok Jeong, Magdalena Stobinska +1
Almost all Bell-inequality experiments to date have used postselection, and therefore relied on the fair sampling assumption for their interpretation. The standard form of the fair…
Effective generation of cat and kitten states
Magdalena Stobińska, G. J. Milburn, Krzysztof Wódkiewicz
We present an effective method of coherent state superposition (cat state) generation using single trapped ion in a Paul trap. The method is experimentally feasible for coherent st…
Measuring photon anti-bunching from continuous variable sideband squeezing
Nicolai B. Grosse, Thomas Symul, Magdalena Stobińska +2
We present a technique for measuring the second-order coherence function of light using a Hanbury-Brown Twiss intensity interferometer modified for homodyne detection.…
Witnessing Entanglement with Second-Order Interference and Stokes Parameters
Magdalena Stobińska, Krzysztof Wódkiewicz
We propose to use Stokes parameter as an entanglement witness for correlated EPR mixed states of light. Such states can be generated with a beam splitter acting on two mixed squeez…
Witnessing Entanglement of EPR States With Second-Order Interference
Magdalena Stobińska, Krzysztof Wódkiewicz
The separability of the continuous-variable EPR state can be tested with Hanbury-Brown and Twiss type interference. The second-order visibility of such interference can provide an…
