Chinese Physicists Achieve Quantum Teleportation Over 60 Miles

MrSeb writes "Chinese physicists are reporting that they've successfully teleported photonic qubits (quantum bits) over a distance of 97 kilometers (60mi). This means that quantum data has been transmitted from one point to another, without passing through the intervening space. It's important to note that the Chinese researchers haven't actually made a photon disappear and reappear 97 kilometers away; rather, they've used quantum entanglement to recreate the same qubit in a new location, with the same subatomic properties as the original qubit. The previous record for transmitting entangled qubits was 16 kilometers, performed by another Chinese team back in 2010 — and perhaps most excitingly, the researchers seem confident that their system will scale up from 97km to distances capable of reaching orbital satellites, at which point we'll actually be able to build a global quantum network for all of our cryptographic needs."

    I hear the next step is transporting economic superpower status over 7,000 miles.

      Here! I'm here... finally. I would have gotten here sooner if the Chinese hadn't been, you know, teleporting me around all morning.

      Hmm... well that sucks. I think they made a mistake and put one of my quarks in upside down -- I feel strange all over now.

    This is part of an international research effort, including schools like Carnegie-Mellon in the US. However, due to the lower costs of photonic qubits in China, it only makes sense to have the majority of experiments carried out over there.
