Hologram of a Single Photon
Radosław Chrapkiewicz, Michał Jachura, Konrad Banaszek +1
The spatial structure of single photons is becoming an extensively explored resource used for facilitating the free-space quantum key distribution and quantum computation as well a…
Magnetically tuned, robust and efficient filtering system for spatially multimode quantum memory in warm atomic vapors
Michał Dąbrowski, Radosław Chrapkiewicz, Wojciech Wasilewski
Warm atomic vapor quantum memories are simple and robust, yet suffer from a number of parasitic processes which produce excess noise. For operating in a single-photon regime precis…
Photon counts statistics of squeezed and multi-mode thermal states of light on multiplexed on-off detectors
Radosław Chrapkiewicz
Photon number resolving detectors can be highly useful for studying the statistics of multi-photon quantum states of light. In this work we study the counts statistics of different…
Mode engineering for realistic quantum-enhanced interferometry
Michał Jachura, Radosław Chrapkiewicz, Rafał Demkowicz-Dobrzański +2
Quantum metrology overcomes standard precision limits by exploiting collective quantum superpositions of physical systems used for sensing, with the prominent example of non-classi…
Shot-by-shot imaging of Hong-Ou-Mandel interference with an intensified sCMOS camera
Michał Jachura, Radosław Chrapkiewicz
We report the first observation of Hong-Ou-Mandel (HOM) interference of highly indistinguishable photon pairs with spatial resolution. Direct imaging of two-photon coalescence with…
