Open-destination Quantum Teleportation
Even if you're not convinced today, quantum computers will replace silicon-based ones within the next twenty years. But how will you be able to check if these quantum computers give you the right answers?

An international team of physicists has entangled five photons for the first time in the world, reports Technology Research News in "Five photons linked." Why is this important? Because it's the minimum number of qubits needed for universal error correction in quantum computing. In other words, they found a way to check computational errors in future quantum computers. The physicists also demonstrated what they call 'open-destination teleportation,' a way to teleport quantum information within and between computers."

"They teleported the unknown quantum state of a single photon onto a superposition of three photons. They were then able to read out this teleported state at any one of the three photons by performing a measurement on the other two photons," adds PhysicsWeb in "Entanglement breaks new record". This will be used in about ten to twenty years to move information among quantum networks. You'll find more details and references in this overview.
