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.

That’s the story – The last original voice from the Manhattan project

The AQM  and Quantum Technology Lab of Università degli Studi di Milano are proud to present the projection of the documentary That’s the story – The last original voice from the Manhattan project, an interview to Roy Glauber, Nobel Prize in 2005 and last surviving member of the theory division of the Manhattan Project.

The projection (in English, 52 min, Italian subtitles) will take place on March 22, 2017, at 14:30 at the Auditorium “Mario Attilio Levi”, via Valvassori Peroni, 21 (Milano).

The executive producer, Prof. Josè I. Latorre, will introduce the documentary.

Congrats to Jacopo and Zeudi!

On January 19th, 2016 our PhD students Jacopo Trapani and Zeudi Mazzotta defended their theses and obtained their PhD degree from the University of Milan.

Jacopo’s thesis is on Stochastic noise approach to non-Markovian decoherence in continuous variable open quantum systems, while Zeudi’s is on Positronium laser excitation in the AEgIS experiment.

We congratulate with Jacopo and Zeudi for their important achievement and we wish them all the best for their future. Well done guys!!

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.
