Talks by Matteo Rossi and Carmen porto on Tue 17 Oct

On Tuesday 17 October, at the  Aula Ottica Quantistica (LITA buliding, 5th floor), Matteo rossi and Carmen Porto will deliver their end-of-year seminars as part of their PhD course requirements.

Here is the program:

11:30 Matteo Rossi

“Quantum reinforcement learning  with superconducting circuits: basic protocols and effects of noise”

12:00 Carmen Porto

“Detection of squeezing by on-chip glass-integrated homodyne analyzer”

Alberto Porzio visiting AQM on April 26

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.

Tommaso Tufarelli 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.
