Microfabrication of large area high-stress silicon nitride membranes for optomechanical devices
E. Serra, M. Bawaj, A. Borrielli +16
In view of the integration of membrane resonators with more complex MEMS structures, we developed a general fabrication procedure for circular shape SiN membranes using Deep Re…
Stochastic Quantum Zeno by Large Deviation Theory
Stefano Gherardini, Shamik Gupta, Francesco Saverio Cataliotti +3
Quantum measurements are crucial to observe the properties of a quantum system, which however unavoidably perturb its state and dynamics in an irreversible way. Here we study the d…
Dynamical two-mode squeezing of thermal fluctuations in a cavity opto-mechanical system
A. Pontin, M. Bonaldi, A. Borrielli +7
We report the experimental observation of two-mode squeezing in the oscillation quadratures of a thermal micro-oscillator. This effect is obtained by parametric modulation of the o…
Dressing the chopped-random-basis optimization: a bandwidth-limited access to the trap-free landscape
Niklas Rach, Matthias M. Müller, Tommaso Calarco +1
In quantum optimal control theory the success of an optimization algorithm is highly influenced by how the figure of merit to be optimized behaves as a function of the control fiel…
Zero-area single photon pulses
L. S. Costanzo, A. S. Coelho, D. Pellegrino +6
Broadband single photons are usually considered not to couple efficiently to atomic gases because of the large mismatch in bandwidth. Contrary to this intuitive picture, here we de…
Parametric description of the quantum measurement process
Pietro Liuzzo-Scorpo, Alessandro Cuccoli, Paola Verrucchi
We present a description of the measurement process based on the parametric representation with environmental coherent states. This representation is specifically tailored for stud…
