Inaccurate (weak) measurements classical and quantum
D. Sokolovski, D. Alonso, S. Brouard
We consider highly inaccurate measurements made on classical stochastic and quantum systems. In the quantum case such a \e{weak} measurement preserves coherence between the system'…
Continuous fuzzy measurement on two-level systems revisited
D. Sokolovski, S. Rusconi, S. Brouard +1
Imposing restrictions on the Feynman paths of the monitored system has in the past been proposed as a universal model-free approach to continuous quantum measurements. Here we revi…
Quantum decoherence of an anharmonic oscillator monitored by a Bose-Einstein condensate
D. Alonso, S. Brouard, D. Sokolovski
The dynamics of a quantum anharmonic oscillator whose position is monitored by a Bose-Einstein condensate (BEC) trapped in a symmetric double well potential is studied. The (non-ex…
Decoherence in a quantum harmonic oscillator monitored by a Bose-Einstein condensate
S. Brouard, D. Alonso, D. Sokolovski
We investigate the dynamics of a quantum oscillator, whose evolution is monitored by a Bose-Einstein condensate (BEC) trapped in a symmetric double well potential. It is demonstrat…
Action scales for quantum decoherence and their relation to structures in phase space
Daniel Alonso, S. Brouard, Jose P. Palao +1
A characteristic action is defined whose magnitude determines some properties of the expectation value of a general quantum displacement operator. These properties are related…
Explicit solution for a Gaussian wave packet impinging on a square barrier
A. L. Perez Prieto, S. Brouard, J. G. Muga
The collision of a quantum Gaussian wave packet with a square barrier is solved explicitly in terms of known functions. The obtained formula is suitable for performing fast calcula…
