Diamonds are forever – entanglement is temporary.

Yes, I admit it.  It’s another post about quantum computing.  I keep writing about computers because I really, really want one.  Plus, I think once the floodgates open, the entire technological system on which communications run will be so dramatically improved that it will make our current system look like the Tandy TRS-80.

Hamish Johnston writes in PhysicsWorld that two diamonds separated by about 15 cm have been put into a state of quantum entanglement. The experiment, carried out by physicists in the UK, was performed at room temperature and involved creating phonons (quantized vibrations) within the crystals. By showing that quantum entanglement can be achieved in two large and distant diamonds at room temperature, the research team has provided further evidence that a practical quantum computer could be within our grasp.
