Entanglement heats up

PhysicsWorld:

“Entanglement” could occur at any temperature and not just in systems cooled to near zero according to new calculations by a team of physicists in the UK, Austria and Portugal. Vlatko Vedral of the University of Leeds and colleagues at the universities of Porto and Vienna have found that the photons in ordinary laser light can be quantum mechanically entangled with the vibrations of a macroscopic mirror, no matter how hot the mirror is. The result is unexpected because hot objects are usually thought of being classical. The finding suggests that macroscopic entanglement is not as difficult to create as previously believed and could have implications for making room-temperature quantum computers in the future

  1. “Quantum computer crashes while it is still turned off. Hours of work yet to be done lost.”

  2. Looks like practical quantum technology isn’t as far off as previously believed. Maybe we’ll have a simulation-running quantum computer by, say, December 21, 2012? Remember Feynman: a reality cannot be simulated (or a simulation of our reality, in his words) is inachievable witout a quantum computer. Could we be getting closer to simulating a reality… maybe ours? lol

  3. Nearer than you think, further away than you like.

    Since 300 qubits can theoretically run more calculations in a second than there are atoms in the universe, we need only give it a minimum of input and it’ll manage the rest itself, right?

    The same way the Universe developed, you know.

    No, wait… the Universe took billions and billions of years to… Damn!
