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…
Sampling the spatial coherence of light
M. Vitek, M. Peterek, D. Koutny +6
We introduce a novel application of the Hartmann sensor, traditionally designed for wavefront sensing, to measure the coherence properties of optical signals. By drawing an analogy…
Optimizing measurement tradeoffs in multiparameter spatial superresolution
J. Řeháček, J. L. Romero, A. Z. Goldberg +2
The quantum Cramér-Rao bound for the joint estimation of the centroid and the separation between two incoherent point sources cannot be saturated. As such, the optimal measurements…
Sensing rotations with multiplane light conversion
M. Eriksson, A. Z. Goldberg, M. Hiekkamäki +4
We report an experiment estimating the three parameters of a general rotation. The scheme uses quantum states attaining the ultimate precision dictated by the quantum Cramér-Rao bo…
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…
Quantum metrology at the limit with extremal Majorana constellations
F. Bouchard, P. de la Hoz, G. Bjork +8
Quantum metrology allows for a tremendous boost in the accuracy of measurement of diverse physical parameters. The estimation of a rotation constitutes a remarkable example of this…
