Upper quantum Lyapunov Exponent and Anosov relations for quantum systems driven by a classical flow
O. Sapin, H. R. Jauslin, S. Weigert
We generalize the definition of quantum Anosov properties and the related Lyapunov exponents to the case of quantum systems driven by a classical flow, i.e. skew-product systems. W…
Control of mixed-state quantum systems by a train of short pulses
D. Sugny, A. Keller, O. Atabek +4
A density matrix approach is developped for the control of a mixed-state quantum system using a time-dependent external field such as a train of pulses. This leads to the definitio…
CNOT gate by adiabatic passage with an optical cavity
N. Sangouard, X. Lacour, S. Guerin +1
We propose a scheme for the construction of a CNOT gate by adiabatic passage in an optical cavity. In opposition to a previously proposed method, the technique is not based on frac…
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…
Fast SWAP gate by adiabatic passage
N. Sangouard, X. Lacour, S. Guérin +1
We present a process for the construction of a SWAP gate which does not require a composition of elementary gates from a universal set. We propose to employ direct techniques adapt…
Decoherence-free creation of atom-atom entanglement in cavity via fractional adiabatic passage
Mahdi Amniat-Talab, Stephane Guerin, Hans-Rudolf Jauslin
We propose a robust and decoherence insensitive scheme to generate controllable entangled states of two three-level atoms interacting with an optical cavity and a laser beam. Losse…
