Ronald Hanson is at QuTech and the Kavli Institute of Nanoscience, Delft University of Technology, Delft 2628 CJ, the Netherlands. The authors show that for a 10-km fibre link, entanglement between ...
Quantum signals are extremely fragile and can be overwhelmed by the intense optical noise generated by conventional internet traffic, requiring costly dedicated infrastructure for quantum networks.
A new technique efficiently detects quantum entanglement using just a small set of measurements. Quantum communication, quantum computing, and quantum sensing all depend on quantum ...
