CQT Talk
Unraveling Superradiance: Entanglement Not Needed, but Smartness Yes
Date/Time: 22-Dec - 22-Dec, 3:00pm
Speaker: Xin Zhang, Technical University of Munich
Venue: CQT Level 3 Seminar Room, S15-03-15
Abstract: Superradiance stands as a hallmark phenomenon in collective quantum optics. Iwill show the unraveling of superradiant dynamics into individual quantumtrajectories via homodyne detection. Remarkably, despite the presence ofentanglement, these trajectories can be effectively treated as product statesfor describing local observables. This findings drastically simplies thecomplexity of superradiant phenomona and can lead to fully classcial and exactdescription in some scenerios, offering both analytical treatment and intuitiveunderstanding. Furthermore, I will show that our approach extends to regimesdominated by subradiant decay. Finally, I will present a novel emergentcollective behavior in waveguide QED uncovered by this trajectory-basedperspective, which renders superradiance robust to strongdisorders.

CQT Conference
The 5th Workshop for Quantum Repeaters and Networks
Date/Time: 27-Apr - 30-Apr, 12:00am
Speaker: Various
Venue: Catapult Rochester, Singapore
The goal of this workshop is to bring the active research community together to discuss the progress, challenges and new possible directions for quantum repeaters and networks. We invite researchers working on key enabling technologies and system integration, protocols for connecting repeaters across network links with high fidelity, architectures for large-scale networks, and applications of distributed quantum entanglement.
The WQRN has been and continues to be a limited-attendance, few-day workshop, in which participants are given the opportunity to share ideas, directions, and concerns to advance the state of the field. Talks are by invitation only and catered to broadly cover the applications, theory, components, and worldwide directions in quantum repeaters and networks. These talks frame group discussion sessions for which all participants are welcome to contribute; participants are also welcome to contribute to a poster session.
Research Areas
Our research areas are aligned with Singapore’s National Quantum Strategy. We host group-led research projects and participate in national-level quantum programmes.
