Field-free two-direction alignment alternation of linear molecules by elliptic laser pulses
D. Daems, S. Guérin, E. Hertz +3
We show that a linear molecule subjected to a short specific elliptically polarized laser field yields postpulse revivals exhibiting alignment alternatively located along the ortho…
Efficient and long-lived field-free orientation of molecules by a single hybrid short pulse
D. Daems, S. Guérin, D. Sugny +1
We show that a combination of a half-cycle pulse and a short nonresonant laser pulse produces a strongly enhanced postpulse orientation. Robust transients that display both efficie…
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 quantum entanglement in arbitrary dimensions
E. Karpov, P. Navez, N. J. Cerf
We have found a quantum cloning machine that optimally duplicates the entanglement of a pair of -dimensional quantum systems. It maximizes the entanglement of formation containe…
Quantum entanglement enhances the capacity of bosonic channels with memory
Nicolas J. Cerf, Julien Clavareau, Chiara Macchiavello +1
The bosonic quantum channels have recently attracted a growing interest, motivated by the hope that they open a tractable approach to the generally hard problem of evaluating quant…
