Quantum Physics

One of the outstanding developments in physics over the past few decades has been the emergence of methods for isolating, controlling and detecting individual ‘quantum objects’, such as single atoms, electrons or photons. What makes these systems so interesting is that quantum-mechanical properties become manifest in, and often govern, their behaviour. The ability to explore quantum phenomena experimentally provided a wealth of fundamental insight, but also gave rise to novel paradigms for device applications — from computing and communication to sensing.

IQST brings together renowned experts in this emerging field, now known as quantum science and technology. Several IQST researchers have made pioneering contributions to key areas of this new field, from establishing colour centres in diamond as room-temperature quantum systems, to developing frameworks for the optimal control of quantum systems, to conceiving fundamental theories of how quantum systems interact with their environment.

IQST researchers continue building the foundation of the field. They work on identifying and isolating quantum mechanical systems that are well protected from external interference yet can be suitably controlled, including ultracold atoms in optical lattices, strongly interacting Rydberg atoms, coherent clusters of nitrogen-vacancy centres in diamond, and arrays of quantum droplets. In parallel, they pursue the mathematical modelling, simulation and optimization of such systems. The comprehensive methodology toolbox thus developed will underpin future quantum technologies that work under realistic experimental conditions.
