Quantum Hypergraph States: A Review
Davide Poderini, Dagmar Bruß, Chiara Macchiavello
Quantum hypergraph states extend the well-studied class of graph states by taking into account multi-qubit interactions through hyperedges. They provide a powerful framework to rep…
Information transmission over an amplitude damping channel with an arbitrary degree of memory
A. D'Arrigo, G. Benenti, G. Falci +1
We study the performance of a partially correlated amplitude damping channel acting on two qubits. We derive lower bounds for the single-shot classical capacity by studying two kin…
Two-qubit non-Markovianity induced by a common environment
C. Addis, P. Haikka, S. McEndoo +2
We study non-Markovianity as backflow of information in two-qubit systems. We consider a setting where, by changing the distance between the qubits, one can interpolate between ind…
Experimental demonstration of time coding quantum key distribution
William Boucher, Thierry Debuisschert
Time coding quantum key distribution with coherent faint pulses is experimentally demonstrated. A measured 3.3 % quantum bit error rate and a relative contrast loss of 8.4 % allow…
Reduced randomness in quantum cryptography with sequences of qubits encoded in the same basis
L. -P. Lamoureux, H. Bechmann-Pasquinucci, N. J. Cerf +2
We consider the cloning of sequences of qubits prepared in the states used in the BB84 or 6-state quantum cryptography protocol, and show that the single-qubit fidelity is unaffect…
Cloning transformations in spin networks without external control
G. De Chiara, R. Fazio, C. Macchiavello +2
In this paper we present an approach to quantum cloning with unmodulated spin networks. The cloner is realized by a proper design of the network and a choice of the coupling betwee…
