Entanglement used to be the gold standard of the quantum world's weirdness, now a new and noisy phenomenon could give us all the benefits with less of the fuss
RAYMOND LAFLAMME works in a magnificent-looking building. The Quantum-Nano Centre on the University of Waterloo campus in Ontario, Canada, boasts an exterior whose alternating strips of reflecting and transparent glass are designed as metaphors for the mysterious nature of the quantum world. Inside, it is even more impressive. Its labs are so well isolated from the outside world that an earthquake will barely move their floors. No electric or magnetic fields can get in where they aren't wanted, and the temperature is controlled to within a single degree. That's especially impressive, considering that human beings bring their hot bodies into the centre to perform experiments at temperatures close to absolute zero.
What a shame, then, if all this cutting-edge engineering proves ...
