Quantum communications have rapidly progressed toward practical, large-scale networks based on quantum key distributions that spearhead the process. Quantum key distribution systems typically include a sender "Alice," a receiver ...
Researchers from the University of Ottawa (uOttawa), in collaboration with the Weizmann Institute of Science and Lancaster University, have observed a hidden quantum transition that can only be seen depending on how observers ...
