Quantum teleportation? Producing spin-entangled electrons

1 julio 2015

Scientists have successfully produced pairs of spin-entangled electrons and demonstrated, for the first time, that these electrons remain entangled even when they are separated from one another on a chip. This research could contribute to the creation of futuristic quantum networks operating using quantum teleportation, which could allow information contained in quantum bits — qubits — to be shared between many elements on chip, a key requirement to scale up the power of a quantum computer. The ability to create non-local entangled electron pairs — known as Einstein-Podolsky-Rosen pairs — on demand has long been a dream.
