Efficient detection of multidimensional single-photon time-bin superpositions
Adam Widomski, Maciej Ogrodnik, Michał Karpiński
The ability to detect quantum superpositions lies at the heart of fundamental and applied aspects of quantum mechanics. The time-frequency degree of freedom of light enables encodi…
