Alberto Porzio from the SPIN institute of CNR (Napoli) will be visiting us on Wed 26 April, 2017.
Alberto will deliver a seminar at 12:30 room A5/S2, LITA Building
Encoding and Direct Detection of Continuous Variable Entanglement in the Orbital Angular Momentum Space
CV entangled beams carrying OAM are successfully generated by converting entangled polarization modes into vortex beams. Entanglement is detected by homodyning in the OAM space with the homodyne local oscillator switching between different OAM states.
Konrad Banaszek from University of Warsaw is going to visit us from Monday 27 Feb (afternoon) to Thursday 2 Mar 2017.
On Tuesday, Feb 28th, 12 AM Konrad is going to deliver a seminar entitled
Restoring quantum enhancement in two-photon interferometry
Continue reading Konrad Banaszek visiting AQM
Tommaso Tufarelli, from University of Nottingham, is visiting AQM from Tuesday 10 to Thursday 12 January.
He will deliver a talk on Wednesday, 11 January at 12:30 in Auletta Ottica Quantistica (5 piano LITA)
Refining the Dicke Model
I will start by reviewing an interesting signature of the “A^2 term” in a simple Dicke model featuring two coupled oscillators [first reported in Phys. Rev. A 91, 063840 (2015)]. Then, I will discuss conditions under which such model could be derived as an approximation to a minimal coupling Hamiltonian in Coulomb-gauge, showing that some additional Hamiltonian terms, not usually discussed in the literature, should be present in the ultrastrong coupling regime.
Elsi-Mari and Massimo Borrelli from University of Turku will visit us from 19 to 22 December.
Elsi-Mari is going to deliver the following seminar on Tue 20, 12 AM, Room A5/S3 (LITA, 5th floor)
Problem of coherent control in non-Markovian open quantum systems
Continue reading Elsi-Mari and Massimo Borrelli visiting AQM

Matteo Brunelli (Queen’s University Belfast) will be visiting us from 24 to 28 October 2016.
He will give a talk on Tuesday 25 October at 12 am in Aula Ottica Quantistica (A5/S2), 5th floor, LITA building, entitled:
Irreversibility and correlations in mesoscopic quantum systems: an optomechanical route
In this talk I will present a theoretical framework to assess the degree of irreversibility of a dissipative process acting on an interacting quantum system. In particular, the entropy production rate of coupled quantum harmonic oscillators can be expressed in a simple form. I will apply the result to the analysis of the optomechanical interaction between a nano-mechanical resonator and a cavity field, and show the agreement between the predictions of our framework and experimental data. In the second part, I will present a quantitative relation between the entropy production rate and the correlations, both total and quantum, built between the mechanical resonator and the cavity field.
