Our recent demonstration of local and scalable detection of genuine multipartite single-photon path entanglement has been published in Quantum. We construct a scalable entanglement witness that can be implemented with local measurements only, and experimentally demonstrate its applicability on an 8-partite single-photon path-entangled state.

The INSPIRE Potentials QSIT Master Internship Award was awarded to Hanan Jaffal by NCCR QSIT. The award aims to encourage excellent women students to carry out their Master's thesis in a laboratory belonging to the NCCR QSIT network, so aiming to increase the number of women researchers in areas such as single photon detectors and other quantum technologies.

Our new results are now out in Nature! We demonstrate a new system based on the concept of “zero-knowledge proofs”, the security of which is based on the physical principle of relativity, that allows for secure data transfer.

Our results from recent experiments on the limits of integrating quantum key distribution (QKD) into existing classical networks have been published in Applied Physics Letters! QKD has already become commercially available recently, however, it is still a challenge to integrate QKD into existing classical networks due to noise introduced by the other signals. In our article we studied how a state-of-the art QKD system can be combined into an existing network.

The QTech group and the whole Department of Applied Physics moved out of our original labs back in 2011. We now have the first tables moved in to the new labs and restored "ancienne école de médecine".

The first entangled two-photon paper from our group is out! In this paper, we study the influence of different degrees of entanglement freedom on the entangled two-photon absorption-induced fluorescence rate of Rhodamine 6G, allowing nonlinear microscopy to be performed in a more efficient way.

We've just been awarded an Innosuisse grant, funded by the Swiss Innovation Agency, to work on the development of a new generation of SNSPDs (Superconducting Nanowire Single-Photon Detectors) to deliver cutting-edge performance for commercial quantum applications. This work will be closely related to industry through our commercial partner ID Quantique.

The GMP Photonics second prize was awarded by General Microtechnology & Photonics (GMP) to Alberto Boaron and Davide Rusca for their experimental and theoretical work on quantum key distribution, under the direction of Prof. Hugo Zbinden. Intended to encourage and motivate young scientists to carry out or continue research in technologies such as photonics and microtechnology, the GMP Photonics prize was awarded for the 5th time, in celebration of the 40th anniversary of the company.

There aren’t many researchers who’ve chosen a lateral point of entry into their field. If you start an academic career later in life, you often have to overcome very specific hurdles. But your previous experience can also help you to find your place in the world of academia.
