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:
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.
