Robust quantum control by shaped pulse
D. Daems, A. Ruschhaupt, D. Sugny +1
Considering the problem of the control of a two-state quantum system by an external field, we establish a general and versatile method that allows the derivation of smooth pulses,…
Spatial multipartite entanglement and localization of entanglement
D. Daems, N. J. Cerf
We present a simple model together with its physical implementation which allows one to generate multipartite entanglement between several spatial modes of the electromagnetic fiel…
Tripartite entanglement in parametric down-conversion with spatially-structured pump
D. Daems, F. Bernard, N. J. Cerf +1
Most investigations of multipartite entanglement have been concerned with temporal modes of the electromagnetic field, and have neglected its spatial structure. We present a simple…
Capacity of a bosonic memory channel with Gauss-Markov noise
Joachim Schäfer, David Daems, Evgueni Karpov +1
We address the classical capacity of a quantum bosonic memory channel with additive noise, subject to an input energy constraint. The memory is modeled by correlated noise emerging…
Field-free molecular alignment induced by elliptically polarized laser pulses: non invasive 3 dimensional characterization
E. Hertz, D. Daems, S. Guérin +3
An investigation of field-free molecular alignment produced by elliptically polarized laser pulses is reported. Experiments are conducted in CO at room temperature. A non invas…
Quantum search by parallel eigenvalue adiabatic passage
D. Daems, S. Guérin, N. J. Cerf
We propose a strategy to achieve the Grover search algorithm by adiabatic passage in a very efficient way. An adiabatic process can be characterized by the instantaneous eigenvalue…
