Quantum-limited detection of arrival time and carrier frequency of time-dependent signals
Patrick Folge, Laura Serino, Ladislav Mišta +4
Precise measurements of both the arrival time and carrier frequency of light pulses are essential for time-frequency-encoded quantum technologies. Quantum mechanics, however, impos…

Angle and angular momentum -- new twist for an old pair
Ladislav Mišta, Hubert de Guise, Jaroslav Řeháček +1
Reaching ultimate performance of quantum technologies requires the use of detection at quantum limits and access to all resources of the underlying physical system. We establish a…

Quantum-limited time-frequency estimation through mode-selective photon measurement
John M. Donohue, Vahid Ansari, Jaroslav Řeháček +5
By projecting onto complex optical mode profiles, it is possible to estimate arbitrarily small separations between objects with quantum-limited precision, free of uncertainty arisi…
