German and Japanese researchers combine approaches previously believed to be incompatible to achieve reliable quantum teleportation ‘at the touch of a button’...
An international team of physicists has succeeded in using continuous entanglement to teleport photonic qubits with accuracies of up to 82 per cent.
Scientists from Johannes Gutenberg University Mainz (JGU) and the University of Tokyo, whose findings have been published in the latest issue of the journal Nature, have become the first to demonstrate a method of quantum teleportation that is both highly reliable and ‘on demand’.
The technique used by the researchers combines two conceptually distinct approaches that were previously thought to be incompatible. The team used the quantum-mechanical entanglement of spatially separated light fields to teleport qubits efficiently and with unprecedented accuracy.
