CHSH Bell Tests For Optical Hybrid Entanglement
Morteza Moradi, Juan Camilo López Carreño, Adam Buraczewski +4
Optical hybrid entanglement can be created between two qubits, one encoded in a single photon and another one in coherent states with opposite phases. It opens the path to a variet…
Rapid training of quantum recurrent neural networks
Michał Siemaszko, Adam Buraczewski, Bertrand Le Saux +1
Time series prediction is essential for human activities in diverse areas. A common approach to this task is to harness Recurrent Neural Networks (RNNs). However, while their predi…
Quantum-enhanced interferometry with large heralded photon-number states
G. S. Thekkadath, M. E. Mycroft, B. A. Bell +11
Quantum phenomena such as entanglement can improve fundamental limits on the sensitivity of a measurement probe. In optical interferometry, a probe consisting of entangled phot…
Quantum simulations with multiphoton Fock states
T. Sturges, T. McDermott, A. Buraczewski +9
Quantum simulations are becoming an essential tool for studying complex phenomena, e.g. quantum topology, quantum information transfer, and relativistic wave equations, beyond the…
Anderson localisation in steady states of microcavity polaritons
Thomas J. Sturges, Mitchell D. Anderson, Adam Buraczewski +6
We present an experimental signature of the Anderson localisation of microcavity polaritons, and provide a systematic study of the dependence on disorder strength. We reveal a cont…
Proposal for distribution of multi-photon entanglement with optimal rate-distance scaling
Monika E. Mycroft, Thomas McDermott, Adam Buraczewski +1
We propose a protocol to perform long-range distribution of near-maximally entangled multiphoton states, allowing versatile applications such as quantum key distribution (QKD) and…
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…
Numerical modeling of exciton-polariton Bose--Einstein condensate in a microcavity
Oksana Voronych, Adam Buraczewski, Michał Matuszewski +1
A novel, optimized numerical method of modeling of an exciton-polariton superfluid in a semiconductor microcavity was proposed. Exciton-polaritons are spin-carrying quasiparticles…
Exciton-polariton X-waves in a microcavity
Oksana Voronych, Adam Buraczewski, Michał Matuszewski +1
We investigate the possibility of creating X-waves, or localized wave packets, in resonantly excited exciton-polariton superfluids. We demonstrate the existence of X-wave traveling…
Numerical model for macroscopic quantum superpositions based on phase-covariant quantum cloning
Adam Buraczewski, Magdalena Stobińska
Macroscopically populated quantum superpositions pose a question to what extent macroscopic world obeys quantum mechanical laws. Recently such superpositions for light, generated b…
Bell Inequality Tests with Macroscopic Entangled States of Light
Magdalena Stobińska, Pavel Sekatski, Adam Buraczewski +2
Quantum correlations may violate the Bell inequalities. Most of the experimental schemes confirming this prediction have been realized in all-optical Bell tests suffering from the…
Filtering of the absolute value of photon-number difference for two-mode macroscopic quantum superpositions
Magdalena Stobińska, Falk Töppel, Pavel Sekatski +5
We discuss a device capable of filtering out two-mode states of light with mode populations differing by more than a certain threshold, while not revealing which mode is more popul…
