Majorization preservation of Gaussian bosonic channels
Michael G. Jabbour, Raúl García-Patrón, Nicolas J. Cerf
It is shown that phase-insensitive Gaussian bosonic channels are majorization-preserving over the set of passive states of the harmonic oscillator. This means that comparable passi…
The GTR-model: a universal framework for quantum-like measurements
Diederik Aerts, Massimiliano Sassoli de Bianchi
We present a very general geometrico-dynamical description of physical or more abstract entities, called the 'general tension-reduction' (GTR) model, where not only states, but als…
An interpolatory ansatz captures the physics of one-dimensional confined Fermi systems
M. E. S. Andersen, A. S. Dehkharghani, A. G. Volosniev +2
Interacting one-dimensional quantum systems play a pivotal role in physics. Exact solutions can be obtained for the homogeneous case using the Bethe ansatz and bosonisation techniq…
Spacetime-constrained oblivious transfer
Damián Pitalúa-García
In 1-out-of-2 oblivious transfer (OT), Alice inputs numbers x_0, x_1, Bob inputs a bit b and outputs x_b. Secure OT requires that Alice and Bob learn nothing about b and x_{\bar{b}…
Device-Independent Bit Commitment based on the CHSH Inequality
Nati Aharon, Serge Massar, Stefano Pironio +1
Bit commitment and coin flipping occupy a unique place in the device-independent landscape, as the only device-independent protocols thus far suggested for these tasks are reliant…
Detection of non-Gaussian entangled states with an improved continuous-variable separability criterion
Anaelle Hertz, Evgueni Karpov, Aikaterini Mandilara +1
Currently available separability criteria for continuous-variable states are generally based on the covariance matrix of quadrature operators. The well-known separability criterion…
A test of optimal laser impulsion for controlling population within the , polyad of
L. Santos, N. Iacobellis, M. Herman +3
Optimal control theory has been employed to populate separately two dark states of the acetylene polyad , by indirect coupling via the ground state. Relevant level e…
Operational formulation of time reversal in quantum theory
Ognyan Oreshkov, Nicolas J. Cerf
The symmetry of quantum theory under time reversal has long been a subject of controversy because the transition probabilities given by Born's rule do not apply backward in time. H…
Secrecy in prepare-and-measure CHSH tests with a qubit bound
Erik Woodhead, Stefano Pironio
The security of device-independent (DI) quantum key distribution (QKD) protocols relies on the violation of Bell inequalities. As such, their security can be established based on m…
Direct dialling of Haar random unitary matrices
Nicholas J. Russell, Levon Chakhmakhchyan, Jeremy L. O'Brien +1
Random unitary matrices find a number of applications in quantum information science, and are central to the recently defined boson sampling algorithm for photons in linear optics.…
Causal and causally separable processes
Ognyan Oreshkov, Christina Giarmatzi
We develop rigorous notions of causality and causal separability in the process framework introduced in [Oreshkov, Costa, Brukner, Nat. Commun. 3, 1092 (2012)], which describes cor…
Steering is an essential feature of non-locality in quantum theory
Ravishankar Ramanathan, Dardo Goyeneche, Sadiq Muhammad +4
A physical theory is called non-local when observers can produce instantaneous effects over distant systems. Non-local theories rely on two fundamental effects: local uncertainty r…
Randomness in post-selected events
Le Phuc Thinh, Gonzalo de la Torre, Jean-Daniel Bancal +2
Bell inequality violations can be used to certify private randomness for use in cryptographic applications. In photonic Bell experiments, a large amount of the data that is generat…
Optimal randomness certification from one entangled bit
Antonio Acín, Stefano Pironio, Tamás Vértesi +1
By performing local projective measurements on a two-qubit entangled state one can certify in a device-independent way up to one bit of randomness. We show here that general measur…
Necessary detection efficiencies for secure quantum key distribution and bound randomness
Antonio Acín, Daniel Cavalcanti, Elsa Passaro +2
In recent years, several hacking attacks have broken the security of quantum cryptography implementations by exploiting the presence of losses and the ability of the eavesdropper t…
Sum-of-squares decompositions for a family of CHSH-like inequalities and their application to self-testing
Cédric Bamps, Stefano Pironio
We introduce two families of sum-of-squares (SOS) decompositions for the Bell operators associated with the tilted CHSH expressions introduced in Phys. Rev. Lett. 108, 100402 (2012…
Hyperdense coding and superadditivity of classical capacities in hypersphere theories
Serge Massar, Stefano Pironio, Damián Pitalúa-García
In quantum superdense coding, two parties previously sharing entanglement can communicate a two bit message by sending a single qubit. We study this feature in the broader framewor…
Simulation of the elementary evolution operator with the motional states of an ion in an anharmonic trap
Ludovic Santos, Yves Justum, Nathalie Vaeck +1
Following a recent proposal of L. Wang and D. Babikov, J. Chem. Phys. 137, 064301 (2012), we theoretically illustrate the possibility of using the motional states of a ion t…
A possible solution to the second entanglement paradox
Diederik Aerts, Massimiliano Sassoli de Bianchi
Entangled states are in conflict with a general physical principle which expresses that a composite entity exists if and only if its components also exist, and the hypothesis that…
Supersymmetric inversion of effective-range expansions
Bikashkali Midya, Jérémie Evrard, Sylvain Abramowicz +2
A complete and consistent inversion technique is proposed to derive an accurate interaction potential from an effective-range function for a given partial wave in the neutral case.…
