Protecting quantum modes in optical fibres
M. A. T. Butt, P. Roth, G. K. L. Wong +7
Polarization-preserving fibers maintain the two polarization states of an orthogonal basis. Quantum communication, however, requires sending at least two nonorthogonal states and t…
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…
Local sampling of the SU(1,1) Wigner function
N. Fabre, A. B. Klimov, G. Leuchs +1
Despite the indisputable merits of the Wigner phase-space formulation, it has not been widely explored for systems with SU(1,1) symmetry, as a simple operational definition of the…
Optimizing the generation of polarization squeezed light in nonlinear optical fibers driven by femtosecond pulses
A. V. Andrianov, N. A. Kalinin, A. A. Sorokin +4
Bright squeezed light can be generated in optical fibers utilizing the Kerr effect for ultrashort laser pulses. However, pulse propagation in a fiber is subject to nonconservative…
Super-resolution enhancement in bi-photon spatial mode demultiplexin
Florence Grenapin, Dilip Paneru, Alessio D'Errico +3
Imaging systems measuring intensity in the far field succumb to Rayleigh's curse, a resolution limitation dictated by the finite aperture of the optical system. Many proof-of-princ…
Anticaustics in a Fabry-Perot interferometer
L. L. Sanchez-Soto, J. J. Monzon, G. Leuchs
We address the response of a Fabry-Perot interferometer to a monochromatic point source. We calculate the anticaustics (that is, the virtual wavefronts of null path difference) res…
