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…
Asymmetric phase-covariant d-dimensional cloning
L. -P. Lamoureux, N. J. Cerf
We consider cloning transformations of d-dimensional states of the form e^{iϕ_0}|0> + e^{iϕ_1}|1> +...+ e^{iϕ_{d-1}}|d-1> that are covariant with respect to rotations of the phases…
Provably Secure Experimental Quantum Bit-String Generation
Louis-Philippe Lamoureux, Edouard Brainis, David Amans +2
Coin tossing is a cryptographic task in which two parties who do not trust each other aim to generate a common random bit. Using classical communication this is impossible, but non…
Experimental quantum key distribution over highly noisy channels
L. P. Lamoureux, E. Brainis, N. Cerf +3
Error filtration is a method for encoding the quantum state of a single particle into a higher dimensional Hilbert space in such a way that it becomes less sensitive to phase noise…
Cloning the entanglement of a pair of quantum bits
Louis-Philippe Lamoureux, Patrick Navez, Jaromir Fiurasek +1
It is shown that any quantum operation that perfectly clones the entanglement of all maximally-entangled qubit pairs cannot preserve separability. This ``entanglement no-cloning''…
