The Impact of Quantum on Optical Fiber Communication
Researchers at the Niels Bohr Institute have broken a longstanding barrier by managing to send single photons—that can't be copied or split and thus are secure—in the network of optical fibers we already have. This opens up a broad range of applications relying on secure quantum . The quantum era is beginning, and the technology has the potential to revolutionize everything from computing to data security and precision measurement. One promising technology behind these secure systems involves semiconductor quantum dots (SQDs), tiny. We demonstrate the distribution of single-photon-level pulses from a mode-locked laser source over a phase-stable fiber link, achieving an optical timing jitter of less than 100 as over 10 minutes of data accumulation. This stability enables a fidelity greater than 0. To bring quantum communications closer to reality, scientists are exploring a groundbreaking approach: integrating quantum data transmission into existing classical. First, we characterised the new set of super conducting nanowire single photon detectors (SNSPD)s at KTH. We measured the X and XX cascade.
