Encoded Quantum Signal Processing for Heisenberg-Limited Metrology
Carlos Ortiz Marrero, Rui Jie Tang, Nathan Wiebe
Entangled quantum probes can achieve Heisenberg-limited measurement precision, but this advantage is typically destroyed by noise. We address this issue by introducing a framework…

Compressing Quantum Fisher Information
Rui Jie Tang, Jeremy Guenza Marcus, Noah Lupu-Gladstein +5
We show that the quantum Fisher information about any phase parameter encoded in a family of pure quantum states can be faithfully compressed into a single qubit, accompanied by a…

Information gain and measurement disturbance for quantum agents
Arthur O. T. Pang, Noah Lupu-Gladstein, Y. Batuhan Yilmaz +4
The traditional formalism of quantum measurement (hereafter ``TQM'') describes processes where some properties of quantum states are extracted and stored as classical information.…
