covariant -parametrized maps
Andrei B. Klimov, Ulrich Seyfarth, Hubert de Guise +1
We propose a practical recipe to compute the -parametrized maps for systems with symmetry using a connection between the and symbols through the action…
Rotation sensing at the ultimate limit
Aaron Z. Goldberg, Andrei B. Klimov, Gerd Leuchs +1
Conventional classical sensors are approaching their maximum sensitivity levels in many areas. Yet these levels still are far from the ultimate limits dictated by quantum mechanics…
Quantum concepts in optical polarization
Aaron Z. Goldberg, Pablo de la Hoz, Gunnar Bjork +4
We comprehensively review the quantum theory of the polarization properties of light. In classical optics, these traits are characterized by the Stokes parameters, which can be geo…
Extremal quantum states
Aaron Z. Goldberg, Andrei B. Klimov, Markus Grassl +2
The striking differences between quantum and classical systems predicate disruptive quantum technologies. We peruse quantumness from a variety of viewpoints, concentrating on phase…
Observation of concentrating paraxial beams
Andrea Aiello, Martin Paur, Bohumil Stoklasa +3
We report,to the best of our knowledge, the first observation of concentrating paraxial beams of light in a linear nondispersive medium. We have generated this intriguing class of…
Achieving the ultimate quantum timing resolution
Vahid Ansari, Benjamin Brecht, Jano Gil-López +5
Accurate time-delay measurement is at the core of many modern technologies. Here, we present a temporal-mode demultiplexing scheme that achieves the ultimate quantum precision for…
Fundamental quantum limits in ellipsometry
L. Rudnicki, L. L. Sanchez-Soto, G. Leuchs +1
We establish the ultimate limits that quantum theory imposes on the accuracy attainable in optical ellipsometry. We show that the standard quantum limit, as usual reached when the…
Compressively certifying quantum measurements
I. Gianani, Y. S. Teo, V. Cimini +4
We introduce a reliable compressive procedure to uniquely characterize any given low-rank quantum measurement using a minimal set of probe states that is based solely on data colle…
Universal compressive characterization of quantum dynamics
Yosep Kim, Yong Siah Teo, Daekun Ahn +6
Recent quantum technologies utilize complex multidimensional processes that govern the dynamics of quantum systems. We develop an adaptive diagonal-element-probing compression tech…
