Quantifying n-photon indistinguishability with a cyclic integrated interferometer has been published in PRX!

A joint paper between IFN-CNR, CNRS and Sapienza on a new method for the quantification of n-photon indistinguishability has been published in PRX! We report on a universal method to measure the genuine indistinguishability of n-photons – a crucial parameter that determines the accuracy of optical quantum computing. Our approach relies on a low-depth cyclic … Leggi tutto

Experimental demonstration of an efficient, semi-device-independent photonic indistinguishability witness

PHOQUSING beneficiary QuiX Quantum, together with the University of Twente, published a new paper: “Experimental demonstration of an efficient, semi-device-independent photonic indistinguishability witness” Efficient and reliable measurements of photonic indistinguishability are crucial to solidify claims of a quantum advantage in photonics. Existing indistinguishability witnesses may be vulnerable to implementation loopholes, showing the need for a … Leggi tutto

Reconfigurable continuously-coupled 3D photonic circuit for Boson Sampling experiments

Boson Sampling is a computational paradigm representing one of the most viable and pursued approaches to demonstrate the regime of quantum advantage. Recent results have demonstrated significant technological leaps in single-photon generation and detection, leading to progressively larger experimental instances of Boson Sampling experiments in different photonic systems. However, a crucial requirement for a fully-fledged … Leggi tutto
