Victor Gondret
Post-Doctoral researcher in Quantum Physics
I am a post-doctoral researcher working in experimental quantum physics. I did my PhD work on collective excitations in a metastable helium Bose-Einstein condensate, in Paris-Saclay University 
. During my PhD, I introduced a novel entanglement criterion which allowed observing entanglement between parametrically driven collective excitations in the quantum fluid. More details on my work can be found in the Research page.
Since October 2025, I have been working at the Amazing Quantum laboratory, led by Carla Hermann at the University of Chile in Santiago 
. The lab specializes in quantum optics and was inaugurated last January. The project I am currently involved in aims to study and generate intense quantum states of light.
My doctoral research focused on the quantum properties of matter waves accurately described by Gaussian states. I will now explore non-Gaussian light after its interaction with matter 
.

First conference in Valparaiso!
I just came back from my first conference in Chile — the Quantum Optics and Solid State Conference, QUOST IX, held in Valparaíso (Chile). It was mainly a national-level conference, which gave me a good overview of the field of quantum optics in Chile  . It was also a great opportunity to meet other researchers in the field and learn about recent advances  . I also had the chance to present the work I did during my PhD thesis. Many thanks to the organizers for this very nice conference!

Our paper on quasiparticle growth was published!
Our recent experimental work on the parametric pair production of collective excitations in a Bose-Einstein condensate was published in Comptes Rendus. Physique, in a special issue honoring Renaud Parentani who initiated this project  . In our manuscript, we compare our observation to Bogoliubov description and observe an excellent agreement  . We observe the exponential growth of the quasiparticle number and measure the growth rate under different excitations. The growth rates we extract from the data does not exhibit a strong reduction compare to the noninteracting prediction which confirms the smallness of interaction between quasiparticles in elongated Bose gas  . See this post for spicy details!

New post-doc in Chile!
I just joined the great Amazing Quantum laboratory, in the University of Chile, at Santiago . I will work on the generation of intense non-Gaussian state of light in a project led by Carla Hermann-Avigliano  .
