A team of scientists at the Max Planck Institute of Quantum Optics established the first working quantum network. IBM is even on the cusp of building actual quantum computer protoypes.
As with most firsts, the network is quite primitive at the moment, and connects a mere two atomic nodes with 60 meters of fiber-optic cable. Since a quantum computer works with qubits, which can have values of 0, 1, or a quantum superposition of both, a quantum Internet would have to able to communicate in qubits. This prototype network accomplishes that by using photons to carry the information around.
Untill sometime back the feasibilty of this thechnology was not quite sure. But Michael Fortsch at the Max Planck Institute for the Science of Light in Erlangen, Germany, and a few pals yesterday said they’ve made a significant breakthrough. These guys reckon they’ve built a photon emitter with a range of…
