Coherent terahertz field tomographic imaging in warm Rydberg vapors
Jan Nowosielski, Marcin Jastrzębski, Wojciech Wasilewski +2
Rydberg atom-based sensors have emerged as highly sensitive tools for terahertz (THz) metrology, yet most current imaging techniques discard crucial phase information. In this Lett…
A warm Rydberg atom-based quadrature amplitude-modulated receiver
Jan Nowosielski, Marcin Jastrzębski, Pavel Halavach +5
Rydberg atoms exhibit remarkable sensitivity to electromagnetic fields, making them promising candidates for revolutionizing field sensors. Unlike conventional antennas, they neith…
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…
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…
Variable electro-optic shearing interferometry for ultrafast single-photon-level pulse characterization
Stanisław Kurzyna, Marcin Jastrzębski, Nicolas Fabre +3
Despite the multitude of available methods, the characterisation of ultrafast pulses remains a challenging endeavour, especially at the single-photon level. We introduce a pulse ch…
