Classical computers require enormous computing power and memory to simulate even the most modest quantum systems. That makes it difficult to model, for example, why certain materials are insulators and others are conductors or even superconductors. R. Feynman had grasped this since the 1980s and suggested to use instead another more controllable and perhaps artificial quantum system as a "quantum simulator". Working examples of quantum simulators today include extremely cold atoms trapped with lasers and magnetic fields and ions in electromagnetic traps. Photons trapped in photonic lattices have also recently emerged as a promising avenue and we are happy to be one of the leading groups in this area. With photons, exotic phenomena thought to exist only in strongly interacting electronic systems, such as Mott transitions, spin-charge separation, and even interacting relativistic theories can be reproduced and understood in more detail. In addition to the "many-body stuff", we are also interested in the "few body" quantum effects found in nano-structures and cold ions systems interfaced with light. These hybrid systems are extremely interesting for the study of quantum effects like quantum interference and entanglement and for their potential use in building quantum memories and quantum processors. Our work is mainly theoretical but we keep close contact with various experimental groups.

Dimitris G. Angelakis joined CQT in 2009 as a Principal Investigator after being a regular visitor and collaborator of the quantum group since 2003. He was born and raised in a small farm in Chania, Crete, Greece, where his childhood curiosity for the wonders of nature led him to study physics in the University of Crete (in spite of almost everyone else’s suggestion to study engineering or medicine). In 1998 he was offered a PhD position in quantum optics under Sir Peter Knight FRS at Imperial College London. He was supported by the Greek State Scholarship Foundation throughout his studies after achieving the highest marks the country in the corresponding national exams. His PhD work in quantum light-matter interactions received the Valerie Myerscough prize in 2000, and then also Institute of Physics UK prize in 2002. In 2001 and at age 25 he was elected college research Fellow at University of Cambridge (St Catharine's JRF) and worked in the Department of Applied Mathematics and Theoretical Physics until 2007. A year after his move to Cambridge, the Centre for Quantum Computation in Cambridge was initiated by Artur Ekert, which he joined to work in implementations of quantum simulation and computation. In 2008 he took over a faculty appointment at his hometown Technical University of Crete, where he in now a tenured associate professor of Quantum Physics at the School of Electrical and Computer Enginnering (part time since 2012). He is known among others for his pioneering work in quantum simulators using light-matter systems.
