Theory and Experiment

The working group develops theoretical foundations for quantum system design and demonstrates quantum advantages specifically in the domain of optical signal processing.

The research agenda includes the following main topics:

Emulation of future hybrid quantum communication networks. Our goal is to facilitate the interaction of theoretically and experimentally oriented groups and thus accelerate the design of new quantum communication networks.

This is one of the first labs in India to manufacture and establish the usage of entangled and heralded single photon sources towards various applications in quantum science and technologies.

Our research group explores the physics of information in quantum devices, which we design, realize and measure. These objects can be viewed as quantum machines processing information. In contrast with ordinary devices, in which quantum mechanics enters only at the level of individual electrons, the degrees of freedom of these machines at the signal level behave according to the laws of quantum mechanics.

The Physics of Quantum Materials research group in the School of Physical Sciences, University of Kent, carries out theoretical and experimental research in Condensed Matter Physics with a strong focus on Quantum Materials. We aim specifically to discover and understand novel properties that could find application in future quantum computing technologies through close collaboration between theory and experiment.

The Quantum Nanophotonics Laboratory is led by Ikerbasque Research Professor Gabriel Molina-Terriza. We are a team of scientists endeavoruing to unveil the physics of the interactions of quantum light and matter at the nanoscale. We experiment with exotic states of light such as single photon states, entangled photons or squeezed states of light and force them to interact with very small structures. We aim to control the quantum features of nanoparticles by exploiting their interaction with light.

We are an interdisciplinary team combining expertise in different fields such as quantum information, quantum and classical cryptography, mathematics and quantum optics. Examples of our research interests include quantum random number generators, quantum key distribution but also any other cryptographic tasks with a quantum advantage. One particular focus of ours is to introduce methods for certifying the quantum behaviour of devices; this is closely related to the device-independent approach to quantum information.

In our work, we focus on supporting and integrating the local scientific community by organizing seminars and meetings, promoting student initiatives and faculty-wide events, and dissemination of information via the website and Twitter. Bearing in mind the international nature of modern science, through fellowship programs, we want to enable cooperation and visits by outstanding foreign scientists for short or long-term visits.
