Photonics for engineered quantum enhanced measurement

Descrizione del progetto

Oltre lo stato dell’arte del rilevamento fotonico potenziato dal punto di vista quantistico

I sensori sono diventati indispensabili in moltissime applicazioni della vita moderna, come il monitoraggio ambientale, la sicurezza, la sanità, il commercio e altre ancora. Il progetto PEQEM, finanziato dal CER, si propone di sviluppare la fotonica integrata, utilizzando una metodologia che combina l’ottica quantistica dei materiali Kerr-non lineari con l’ingegneria dei dispositivi fotonici. La tecnologia completamente integrata di generazione e rilevamento della luce schiacciata che verrà sviluppata fornirà sensori avanzati per la misurazione dell’assorbimento e della fase, superando le prestazioni dei sensori convenzionali. Le applicazioni di rilevamento e misurazione potenziate dal punto di vista quantistico comprendono esperimenti di metrologia quantistica di prossima generazione, misurazione di campioni fotosensibili, caratterizzazione precisa di componenti fotonici e rilevamento di tracce di gas.

Obiettivo

Advances in measurement always lead to dramatic advances in science and in technology. Our society is now heavily dependent on the sensors that permeate environmental monitoring, security, healthcare and commerce. This is quantified by the global sensing market worth rising from $110 billion in 2015 to $124 billion in 2016, and is predicted to continue to rise to $240 billion by 2022. Now, our rapidly growing understanding of how to control quantum systems vastly expands both the potential performance and application for measurement and sensing using quantum-enhanced techniques. But these techniques will only efficiently find disruptive use once they are engineered for robustness, deliver desired operational parameters and are shown to work in a platform that can be mass-produced.

This project adopts an engineering approach to the disciplines of photonic quantum enhanced sensing and squeezed light quantum optics. We will develop integrated photonics that are tailored to enable miniature, deployable and ultimately low cost sensors that exceed the state of the art through (i) exploitation of the quantum mechanics of light and by (ii) developing the requisite high performance of components in an integrated photonics platform. The methodology is to combine quantum optics of Kerr-nonlinear materials that generate squeezed light and quantum state detection with photonic device engineering. We will benchmark device performance using quantum metrology techniques. By the end of this project, we will have developed all-integrated squeezed light generation and detection technology, that provides enhanced sensors for absorption and phase measurements beyond the shot noise limit --- the hard limit that bounds performance of state of the art “classical” sensors. Applications include next generation quantum metrology experiments, measurement of photo-sensitive samples, precise characterization of photonic components and trace gas detection.
