For more than 20 years, quantum researchers have wondered whether a quantum system can have maximum entanglement in the presence of noise. A mathematician from Spain recently answered the question: No.
Four researchers from the Institute of Photonics at Leibniz University Hannover have developed a new transmitter-receiver concept for transmitting entangled photons over an optical fiber. This breakthrough could enable the ...
