Rotation-induced mixing in red giant stars
A. Palacios, C. Charbonnel, S. Talon +1
Red giant stars, both in the field and in globular clusters, present abundance anomalies that can not be explained by standard stellar evolution models. Some of these peculiarities…
Experimental demonstration of quantum memory for light
Brian Julsgaard, Jacob Sherson, J. Ignacio Cirac +2
The information carrier of today's communications, a weak pulse of light, is an intrinsically quantum object. As a consequence, complete information about the pulse cannot, even in…
Secure Coherent-state Quantum Key Distribution Protocols with Efficient Reconciliation
G. Van Assche, S. Iblisdir, N. J. Cerf
We study the equivalence between a realistic quantum key distribution protocol using coherent states and homodyne detection and a formal entanglement purification protocol. Maximal…
The optimal cloning of quantum coherent states is non-Gaussian
N. J. Cerf, O. Krueger, P. Navez +2
We consider the optimal cloning of quantum coherent states with single-clone and joint fidelity as figures of merit. Both optimal fidelities are attained for phase space translatio…
Noise resistance of adiabatic quantum computation using random matrix theory
Jeremie Roland, Nicolas J. Cerf
Besides the traditional circuit-based model of quantum computation, several quantum algorithms based on a continuous-time Hamiltonian evolution have recently been introduced, inclu…
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…
