Simple broadband signal detection at the fundamental limit
Anthony M. Polloreno, Graeme Smith
The paper derives a fundamental limit on how quickly a weak, broadband oscillatory signal can be detected and proposes an all‑analog measurement scheme that nearly reaches this lim…

Secure quantum ranging
Yunkai Wang, Graeme Smith, Alex May
Determining and verifying an object's position is a fundamental task with broad practical relevance. We propose a secure quantum ranging protocol that combines quantum ranging with…

Gaussian quantum data hiding
Yunkai Wang, Graeme Smith
Quantum data hiding encodes a hidden classical bit to a pair of quantum states that is difficult to distinguish using a particular set of measurement, denoted as . In this work,…
