Quantum Information and Control delves into the fundamental physics of quantum systems, unlocking their potential to transform technology. This theme focuses on the precise manipulation of matter-based and photon-based quantum states, as well as the interfaces between them.
By harnessing principles like superposition and entanglement, researchers aim to achieve tasks unattainable by classical systems. Central to this field are quantum networks, which integrate spin qubits and photons to enable long-distance, low-loss quantum information transfer and scalable quantum computation. Quantum nonlinear optics investigates photon-photon interactions within nonlinear materials at the single-photon level, advancing optical quantum technologies capable of generating entanglement between spatial and temporal modes on demand.
Alongside addressing challenges in controlling few- and many-body systems and overcoming barriers to scalability, this research seeks to pioneer entirely new paradigms for controlling quantum systems, opening unforeseen avenues for quantum communication, computation, and sensing.

Quantum NetworksQuantum networks leverage the inherent properties of quantum systems to enable secure and efficient communication as well as scalable computation. Spin qubits, often trapped within solid-state systems, serve as reliable hosts and processors of quantum information. By interfacing these spin qubits with photons, information can travel over long distances with minimal loss. This fusion of spin and photonics holds promise for advancing quantum computing and cryptography, paving the way for a future where quantum networks redefine information exchange. |
Quantum Nonlinear OpticsQuantum nonlinear optics explores the phenomena that arise when multiple photons interact within a quantum system. These interactions can lead to effects such as photon-photon scattering and entanglement generation. By harnessing these nonlinear processes, researchers aim to develop novel quantum technologies such as quantum gates for quantum computing and quantum-enhanced sensing devices. This theme holds potential for revolutionizing information processing and communication by exploiting the intricate interplay between photons at the quantum level. |
