QUROPE Quantum Information Processing and Communication in Europe

Quantum engineering is a revolutionary approach to quantum technology. It encompasses both fundamental physics and the broad engineering skill-set necessary to meet the practical challenges of the future.

Our goal in the Centre for Quantum Photonics is to explore fundamental aspects of quantum mechanics, as well as work towards future photonic quantum technologies by generating, manipulating and measuring single photons as well as the quantum systems that emit these photons.

The Centre spans the School of Physics and Department of Electrical and Electronic Engineering in the Faculties of Science and Engineering, and the Centre for Nanoscience and Quantum Information.

Quantum Engineering Technology Labs:
QET Labs delivers a radically new generation of machines that exploit quantum physics to transform our lives, society and economy:

Quantum transport in quantum dot arrays and low

dimensional systems : 

Long range charge, spin and qubit transfer at the nanoscale.

Effect of hyperfine and spin orbit interactions: spin decoherence and relaxation.

Quantum transport of strongly correlated electrons.

Quantum charge and spin transfer in low dimensional systems with non trivial topology.

AC driven transport in nanostructures:

The group works on theoretical problems in quantum transport. Central research topics include quantum engineering with dynamic single-electron sources as well as electrical noise and fluctuations in nano-scale conductors. We are also interested in correlations and entanglement in many-body systems as well as the statistical mechanics of small quantum devices.

QCD group carries out experimental research on silicon and superconducting quantum nanoelectronics. The main research goals include engineered quantum environments, single-electron pumps, and microwave photon detectors. In addition, QCD is known for its work on monopoles in ultracold atomic gases.

We now have the ability to build electronic devices at the nanoscale and operate them at millikelvin temperatures, and this has opened up the possibility to design, operate and utilise devices based on quantum physics. Quantum devices have been used in electrical metrology for decades and now nanoscale single-electron current sources are about to take their place in the realization of the ampere.

The superconducting quantum computer has very recently reached the theoretical thresholds for fault-tolerant universal quantum computing and a quantum annealer based on superconducting quantum bits, qubits, is already commercially available. However, several fundamental questions on the way to efficient large-scale quantum computing have to be answered: qubit initialization, extreme gate accuracy, and quantum-level power consumption.

The past couple of years have witnessed the rise of on-chip quantum optics. This has been enabled by the fabrication of high-finesse superconducting resonators made out of coplanar waveguides, and by the coupling of these resonators to superconducting quantum bits, qubits. This so-called circuit quantum electrodynamics (cQED) has proven superior compared with the standard cavity QED with photons coupled to atoms in three-dimensional space.
