Background-free calibrated electric-field imaging with Rydberg-state fluorescence and Autler-Townes splitting
Gabriel Ko, Wiktor Krokosz, Mateusz Mazelanik +2
We demonstrate a spatially resolved method for imaging millimeter-wave (mmWave) electric fields using Rydberg-state fluorescence in a warm atomic vapor. By utilizing a multi-photon…
Electric-field metrology of a terahertz frequency comb using Rydberg atoms
Wiktor Krokosz, Jan Nowosielski, Bartosz Kasza +4
Terahertz radiation finds an increasing number of applications, yet efficient generation and detection remain a challenge and an active area of research. In particular, the precise…
A Rydberg atom based system for benchmarking mmWave automotive radar chips
Sebastian Borówka, Wiktor Krokosz, Mateusz Mazelanik +2
Rydberg atomic sensors and receivers have enabled sensitive and traceable measurements of RF fields at a wide range of frequencies. Here we demonstrate the detection of electric fi…
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…
