Quantum information and sensing technologies research
Explore our work in quantum information and sensing technologies
Quantum information technology covers a broad area of physics, taking advantage of phenomena such as quantum superposition, in which particles can be in different states at the same time, and quantum entanglement, where particles can be connected without any direct physical interaction.
Through our research, we're developing new technologies, including applications for high-precision measurements, exponential computational speed-up, and secure communication.
Quantum computers will help us solve complex problems much faster than supercomputers of today – or the future – with impacts for our security and make possible advances in machine learning and artificial intelligence.
Quantum sensors exploit quantum interference and/or entanglement, to achieve a higher sensitivity and resolution for biomedical, environmental, imaging and navigation applications. They can also be used to better test the fundamental laws of physics.
The development of quantum technologies will boost the quantum industry, and enhance the health and wellbeing of our society. It will also improve the security of government institutions, and the sustainability of our environment.
Our research is regularly published in international journals, such as Nature Journals, Physical Review Letters, New Journal of Physics, Physical Review A, Quantum Information Processing, and Optics Express.
Our work covers the following topics
- High-precision quantum sensing and imaging
- Quantum computing, boson sampling and quantum computational speed-up
- Quantum simulations of complex systems
- Quantum secure communication
Methods and facilities
Our work aims at the theoretical study of novel schemes for quantum technologies – and their experimental realisation toward the development of a quantum industry.
Along with a supercomputer facility in the ICG, facilities include a quantum optics lab including lasers, nonlinear crystals, optics and photon detectors, and a time-resolved photoluminescence system.
