Non-classical correlations between photons and phonons of center-of-mass motion of a mechanical oscillator
Ivan Galinskiy, Georg Enzian, Michał Parniak +1
We demonstrate non-classical correlations between phonons and photons created using opto-mechanical spontaneous parametric down-conversion in a system based on a soft-clamped ultra…
Beating the spectroscopic Rayleigh limit via post-processed heterodyne detection
Wiktor Krokosz, Mateusz Mazelanik, Michał Lipka +4
Quantum-inspired superresolution methods surpass the Rayleigh limit in imaging, or the analogous Fourier limit in spectroscopy. This is achieved by carefully extracting the informa…
Spectrum-to-position mapping via programmable spatial dispersion implemented in an optical quantum memory
Marcin Jastrzębski, Stanisław Kurzyna, Bartosz Niewelt +3
Spectro-temporal processing is essential in reaching ultimate per-photon information capacity in optical communication and metrology. In contrast to the spatial domain, complex mul…
Ultrafast electro-optic Time-Frequency Fractional Fourier Imaging at the Single-Photon Level
Michał Lipka, Michał Parniak
The Fractional Fourier Transform (FRT) corresponds to an arbitrary-angle rotation in the phase space, e.g. the time-frequency (TF) space, and generalizes the fundamentally importan…
Experimental implementation of the optical fractional Fourier transform in the time-frequency domain
Bartosz Niewelt, Marcin Jastrzębski, Stanisław Kurzyna +4
The fractional Fourier transform (FrFT), a fundamental operation in physics that corresponds to a rotation of phase space by any angle, is also an indispensable tool employed in di…
Microwave electrometry with multi-photon coherence in Rydberg atoms
Zheng Yin, Shengfang Zhao, Yuan He +4
A scheme for measurement of microwave (MW) electric field is proposed via multi-photon coherence in Rydberg atoms. It is based on the three-photon electromagnetically induced absor…
