Quantum-inspired exoplanet detection in the presence of experimental imperfections
Tomasz Linowski, Konrad Schlichtholz, Giacomo Sorelli
Ideal spatial demultiplexing (SPADE) is proven to be a quantum-optimal tool for exoplanet detection, i.e., asymmetric source discrimination. However, recent investigations into the…

Formal relation between Pegg-Barnett and Paul quantum phase frameworks
Tomasz Linowski, Konrad Schlichtholz, Åukasz Rudnicki
The problem of defining a hermitian quantum phase operator is nearly as old as quantum mechanics itself. Throughout the years, a number of solutions was proposed, ranging from abst…

Spectral and temporal metrology with bandlimited functions and finite-time measurements
Åukasz Rudnicki, Tomasz Linowski
We perform an analysis supplementing the metrology toolbox in the time-frequency domain. While the relevant time-frequency-based metrological protocols can be borrowed from the spa…
