All-fiber microendoscopic polarization sensing at single-photon level aided by deep-learning
Martin Bielak, Dominik Vašinka, Miroslav Ježek
The polarization of light conveys crucial information about the spatial ordering and optical properties of a specimen. However, precise polarization measurement in challenging cond…
Measurement-device agnostic quantum tomography
Robert Stárek, Martin Bielak, Miroslav Ježek
Characterization of quantum states and devices is paramount to quantum science and technology. The characterization consists of individual measurements, which must be precisely kno…
Experimental noiseless quantum amplification of coherent states of light by two-photon addition and subtraction
Michal Neset, JiÅà Fadrný, Martin Bielak +3
Noiseless quantum amplifiers are probabilistic quantum devices that enhance amplitude of coherent states without adding any noise, which has far reaching applications in quantum op…
Experimental preparation of multiphoton-added coherent states of light
JiÅà Fadrný, Michal Neset, Martin Bielak +3
Conditional addition of photons represents a crucial tool for optical quantum state engineering and it forms a fundamental building block of advanced quantum photonic devices. Here…
