QTeQ on Nature Photonics!

In the beginning of 2020, QTeQ’s was published in Nature Photonics (https://www.nature.com/articles/s41566-019-0553-9)! This work, result of the fruitful collaboration with Sylvain Gigan’s group at the Laboratoire Kastler Brossel (ENS-PSL) in Paris, explored the potential of complex media, embodied here as multimode optical fibres, for quantum information processing and computation.

)! This work, result of the fruitful collaboration with Sylvain Gigan’s group at the Laboratoire Kastler Brossel (ENS-PSL) in Paris, explored the potential of complex media, embodied here as multimode optical fibres, for quantum information processing and computation.

The team in Paris demonstrated excellent control over the the two-photon dynamics throughout a multimode fibre, as well as the capability to control independently spatial and polarisation degrees of freedom of single photons. Scaling up such technology could allow for easier control of complex dynamics without needing to fine-tune the devices implementing the quantum evolution.

Well done and congrats on the article!!

QTeQ’s research work chosen as Editor’s Suggestion in PRL!

QTeQ’s recent research work has been selected as Editor’s Suggestion in the prestigious Phys. Rev. Lett (https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.125.080601). In this recent work, with leading author Dr Massimiliano Rossi, from the Niels Bohr Institute in Copenaghen, a team of physicists led by our Dr Alessio Belenchia explored the thermodynamics of a mesoscopic quantum system under continuous monitoring.

The experimental component of the work, carried out by the group of Prof Schliesser in Copenhagen, in combination with the theoretical developments achieved by the QTeQ in collaboration with Prof Landi from São Paolo, was able to directly observe for the first time the stochastic entropy production and the effect of continuous measurement on a mesoscopic quantum mechanical oscillator. These results, while important from the conceptual point of view, open also the way to thermodynamically optimal protocols with mesoscopic quantum systems.

Very well done and congratulations on the great article!!
