Security of Quantum Key Distribution with Coherent States and Homodyne Detection

S. Iblisdir, G. Van Assche, N. J. Cerf

We assess the security of a quantum key distribution protocol relying on the transmission of Gaussian-modulated coherent states and homodyne detection. This protocol is shown to be…

Quantum key distribution using gaussian-modulated coherent states

F. Grosshans, G. Van Assche, J. Wenger +3

Quantum continuous variables are being explored as an alternative means to implement quantum key distribution, which is usually based on single photon counting. The former approach…

More on a SUSYQM approach to the harmonic oscillator with nonzero minimal uncertainties in position and/or momentum

C. Quesne, V. M. Tkachuk

We continue our previous application of supersymmetric quantum mechanical methods to eigenvalue problems in the context of some deformed canonical commutation relations leading to…

Cosmological billiards and oxidation

Sophie de Buyl, Marc Henneaux, Bernard Julia +1

We show how the properties of the cosmological billiards provide useful information (spacetime dimension and -form spectrum) on the oxidation endpoint of the oxidation sequence…

Optimized time-dependent perturbation theory for pulse-driven quantum dynamics in atomic or molecular systems

D. Daems, S. Guérin, H. R. Jauslin +2

We present a time-dependent perturbative approach adapted to the treatment of intense pulsed interactions. We show there is a freedom in choosing secular terms and use it to optimi…

Further explorations of Skyrme-Hartree-Fock-Bogoliubov mass formulas. II: Role of the effective mass

S. Goriely, M. Samyn, M. Bender +1

We have constructed four new complete mass tables, referred to as HFB-4 to HFB-7, each one including all the 9200 nuclei lying between the two drip lines over the range of Z and N>…

How to measure squeezing and entanglement of Gaussian states without homodyning

Jaromir Fiurasek, Nicolas J. Cerf

We propose a scheme for measuring the squeezing, purity, and entanglement of Gaussian states of light that does not require homodyne detection. The suggested setup only needs beam…
