Project pages

Example project title

One sentence, describing what this project is is about.

Team members: A, B, C

QKD receiver characterization (Polarization)

Calibrated polarization-state generator to characterize polarization analysis modules in QKD receivers and rigorously quantify the impact on secure key rates.

Team members: Elias X. Huber, various AI agents (open to join forces with other humans as well, you can reach me at elias.x.huber[at typical nus sufix]; please note though that I will likely do the experiment at UTown (CREATE Tower), my schedule tends to be a bit inflexible for team-work, and I am a theorist with no lab experience).

Control and measurement in the bosonic cQED system

Using control and measurement methods to characterize a dispersively coupled single superconducting cavity and single transmon qubit system, with a thorough review of the theories and experimental techniques behind it.

Team members: Grace Pang and Seungwon Jin

Multi-tone RFSoC driver for an AOM

A multi-tone RF synthesizer on an RFSoC board to drive an acousto-optic modulator(AOM).

Team members: Mani Aarthy

Placeholder for project title

TBD. Team members Wang Ziyan and Wu Jinbin

Resources

Some hopefully useful references should go here.

Recommended literature

• Bahaa E. A. Saleh, Malvin Carl Teich: Fundamentals of Photonics, Wiley; available as e-book in NUS. Excellent reference book for many optics topics.
• Mark Fox: Quantum Optics: An Introduction, Oxford University Press; available as e-book in NUS. Nice book on traditional quantum optics topics.
• Christopher C. Davis: Lasers and electro-optics, Cambridge; available as e-book in NUS. Good overall book on optics-related aspects useful for controlling quantum systems.
