Quantum Teleportation

...is the transmission of data at faster-than-light speeds using quantum-entangled "qubits." A team of scientists has just performed the first such transmission while keeping the data intact. From Engadget:

with full transmission integrity achieved -- as in blocks of qubits being destroyed in one place but instantaneously resurrected in another, without affecting their superpositions -- we're now one huge step closer to secure, high-speed quantum communication.

The long-range import of this achievement is instant communication capability. Imagine real-time conversation between Earth and Mars, or no-lag audio and video between any two points on Earth.
