Asking new questions: From quantum physics and mater­i­als to innov­at­ive integ­rated devices

IQST explores various model systems and cutting-edge techniques to study the behaviour of matter and photons

Our research focuses on funda­mental studies of the proper­ties of matter and photons. Through the use of model systems and the devel­op­ment of innov­at­ive techniques, IQST aims to address funda­mental scientific questions including:

  • Invest­ig­ate entan­gle­ment, correl­a­tions, and many-body effects in complex quantum systems at differ­ent length and time scales.
  • Gain insight into quantum phase trans­itions in matter and photonic systems, and under­stand the mechan­isms driving them.
  • Study emergent phenom­ena and topolo­gical states to discover poten­tial novel behaviour arising from intric­ate quantum inter­ac­tions.

IQST explores these questions using a range of quantum-mechanical systems and techniques:

Photonic systems:
Quantum light and quantum optomech­an­ical systems are used as photonic platforms, both as quantum systems in their own right and as a means of controlling matter-based systems.

Matter and spin qubits:
We are explor­ing qubits based on atoms, molecules and spins to gain insight into their quantum proper­ties and behaviour, with a focus on controlled manip­u­la­tion of these systems.

New model systems and novel techniques:
IQST research­ers study molecules and atoms on surfaces to reveal how the quantum proper­ties of these new model systems are affected by surface inter­ac­tions and chemical struc­tures. We also use mater­i­als chemistry to enhance and under­stand differ­ent quantum proper­ties. We are devel­op­ing quantum probes in condensed-matter systems to gain new insights into quantum states and their behaviour, and to probe and manip­u­late matter-photon interactions.

IQST conducts forefront research at the inter­sec­tion of computer science, electrical engin­eer­ing, photonics and physics, to develop ground-breaking quantum devices:

IQST aims to harness the power of photonics and electron­ics as trans­form­at­ive tools to advance quantum science and drive the inven­tion of novel quantum devices. The overarch­ing goal is to achieve performance-oriented integ­ra­tion, enabling pioneer­ing quantum exper­i­ments that lead to estab­lish­ing a quantum advant­age and intro­duce new function­al­it­ies. We tackle this challenge from several fronts:

Design and automa­tion software and co-integration:
We research novel designs for integ­rated quantum devices to accel­er­ate innov­a­tion through stream­lined processes, includ­ing automated designs across photonics, electron­ics, mater­i­als, and other quantum systems, and provid­ing device descrip­tions at the quantum level to gain insight into device behaviour and inter­ac­tions of quantum devices. IQST aims to estab­lish a strong link between hardware design and software method­o­lo­gies, thereby enabling the efficient devel­op­ment of integ­rated quantum devices.

Photonic integ­ra­tion and electronic integration:
We research various integ­rated photonic platforms, with the aim of both improv­ing perform­ance and incor­por­at­ing new function­al­it­ies. IQST’s research expands to the integ­ra­tion of electron­ics includ­ing cryogenic electron­ics and non-linear inter­ac­tions. Our goal is to enhance the perform­ance and control of quantum devices and to harness their poten­tial for new types of quantum opera­tions. In partic­u­lar, we research techniques for co-integrating electronic and photonic compon­ents in quantum devices.
