Quantum information science and technology brings quantum mechanics and information theory together and includes, but is not limited to, quantum computation, quantum communication, and quantum metrology.

In Quantum Dynamics Unit we study a unique system of elementary quantum particles, electrons, floating on the surface of liquid helium. Helium, which is a noble gas at room temperature, becomes liquid when it is cooled down in a refrigerator. Unlike any other substances encountered in nature, helium remains liquid even at the absolute zero temperature, thus contains no impurities and presents the cleanest substrate for electrons. At such low temperatures, electrons behave as quantum objects with charge and spin degrees of freedom, which can be harnessed for interesting applications, such as quantum computing. In Quantum Dynamics Unit we use a variety of experimental techniques such as microwave engineering and microfabrication to study properties of electrons on helium and harness them for quantum technology.

The Quantum Engineering and Design Unit explores how we can transfer today ideas in quantum information science into tomorrow’s quantum technologies through system design.

The research unit will conduct theoretical research into all aspects of quantum information processing with focus on the nature of randomness and its applications in secure communication.

We study in theory and experiments the engineering of quantum devices built from different subsystems that can collectively perform beyond the individual capabilities of their parts.

We explore novel physics, leads to future nano-electronics and nano-spintronics, and design novel charge, spin, orbital, and/or phonon states in a variety of engineered quantum materials.

We study synthetic few- and many-body systems made from ultra-cold atomic gases and develop methods to quantify, control, and engineer their properties and their dynamics.
