Scientists Achieve On-Demand Quantum Teleportation For The First Time
Quantum Teleportation of Light Waves A Schrödinger's cat is a quantum superposition of two light waves. The two light waves are interpreted respectively as a living cat and a dead cat. Their quantum superposition hints to a "quantum" cat paradoxically alive and dead at the same time. The figures shown are numerical functions reconstructed from the measured light amplitudes at the input and output of the experiment. © Science/AAAS Quantum teleportation, more reliable than ever before, at greater distances than ever before. Quantum teleportation has taken another step forward, thanks to two complimentary experiments, one from ETH Zurich and one from the University of Tokyo. The researchers have demonstrated the most reliable yet version of quantum teleportation--what Nature is calling "quantum teleportation on demand." A quick explanation of quantum teleportation, from the Nature abstract: Generically, teleportation protocolsproceed by three steps (Fig. 1): a pair of quantum systems in an entangled state is produced and distributed,...
