Boson Sampling as a Probe of Chaotic and Integrable Quantum Dynamics in a Photonic Chip
Yuancheng Zhan, Khen Cohen, Norman T. W. Koo +8
Quantum chaos plays a key role in understanding complex quantum dynamics, while integrated photonics offers unique advantages for quantum applications, including high-speed operati…

Projected Optimal Sensors from Operator Orbits
Sooryansh Asthana, Yeshma Ibrahim, Norman Tze Wei Koo +1
We unify Ramsey, twist-untwist, and random quantum sensors using operator algebra and account for the Fisher scaling of various sensor designs. We illustrate how the operator orbit…

Timing quantum emission: Coherence, superradiance, and entanglement in order
Nur Fadhillah Binti Rahimi, Norman Tze Wei Koo, Daniel Schumayer +3
We investigate the short-term temporal dynamics of superradiance in closely spaced quantum emitters. Building on Dickes 1954 framework, we analyze the sequential emergence of coher…
