Symmetry-assisted adversaries for quantum state generation
Andris Ambainis, Loïck Magnin, Martin Roetteler +1
We introduce a new quantum adversary method to prove lower bounds on the query complexity of the quantum state generation problem. This problem encompasses both, the computation of…
Gaussian capacity of the quantum bosonic channel with additive correlated Gaussian noise
Joachim Schäfer, Evgueni Karpov, Nicolas J. Cerf
We present an algorithm for calculation of the Gaussian classical capacity of a quantum bosonic memory channel with additive Gaussian noise. The algorithm, restricted to Gaussian i…
Secure device-independent quantum key distribution with causally independent measurement devices
Lluis Masanes, Stefano Pironio, Antonio Acin
Device-independent quantum key distribution aims to provide key distribution schemes whose security is based on the laws of quantum physics but which does not require any assumptio…
Quantum optical coherence can survive photon losses: a continuous-variable quantum erasure correcting code
Mikael Lassen, Metin Sabuncu, Alexander Huck +4
A fundamental requirement for enabling fault-tolerant quantum information processing is an efficient quantum error-correcting code (QECC) that robustly protects the involved fragil…
A family of loss-tolerant quantum coin flipping protocols
N. Aharon, S. Massar, J. Silman
We present a family of loss-tolerant quantum strong coin flipping protocols; each protocol differing in the number of qubits employed. For a single qubit we obtain a bias of 0.4, r…
Ab initio calculation of H + He charge transfer cross sections for plasma physics
J. Loreau, K. Sodoga, D. Lauvergnat +2
The charge transfer in low energy (0.25 to 150 eV/amu) H() + He collisions is investigated using a quasi-molecular approach for the as well as the first two $n=…
Mutually Unbiased Bases and Semi-definite Programming
Stephen Brierley, Stefan Weigert
A complex Hilbert space of dimension six supports at least three but not more than seven mutually unbiased bases. Two computer-aided analytical methods to tighten these bounds are…
Symmetry, Compact Closure and Dagger Compactness for Categories of Convex Operational Models
Howard Barnum, Ross Duncan, Alexander Wilce
In the categorical approach to the foundations of quantum theory, one begins with a symmetric monoidal category, the objects of which represent physical systems, and the morphisms…
Looking for symmetric Bell inequalities
Jean-Daniel Bancal, Nicolas Gisin, Stefano Pironio
Finding all Bell inequalities for a given number of parties, measurement settings, and measurement outcomes is in general a computationally hard task. We show that all Bell inequal…
Guess your neighbour's input: a multipartite non-local game with no quantum advantage
M. L. Almeida, J. -D. Bancal, N. Brunner +3
We present a multipartite nonlocal game in which each player must guess the input received by his neighbour. We show that quantum correlations do not perform better than classical…
Proposal for Implementing Device-Independent Quantum Key Distribution based on a Heralded Qubit Amplification
Nicolas Gisin, Stefano Pironio, Nicolas Sangouard
In device-independent quantum key distribution (DIQKD), the violation of a Bell inequality is exploited to establish a shared key that is secure independently of the internal worki…
Spatial multipartite entanglement and localization of entanglement
D. Daems, N. J. Cerf
We present a simple model together with its physical implementation which allows one to generate multipartite entanglement between several spatial modes of the electromagnetic fiel…
Tripartite entanglement in parametric down-conversion with spatially-structured pump
D. Daems, F. Bernard, N. J. Cerf +1
Most investigations of multipartite entanglement have been concerned with temporal modes of the electromagnetic field, and have neglected its spatial structure. We present a simple…
Quantum walks can find a marked element on any graph
Hari Krovi, Frédéric Magniez, Maris Ozols +1
We solve an open problem by constructing quantum walks that not only detect but also find marked vertices in a graph. In the case when the marked set consists of a single verte…
