It's a big month for quantum computing. Earlier today we reported that scientists had sustained a quantum computer for 39 minutes at room temperature instead of having to cool it to near-absolute-zero first, meaning we are that much closer to Ludicrous Speed consumer computers. Now it has come to light that photons can be measured, measured, and measured again--without having to absorb and thus destroy them. The upshot? It's a big month for quantum computing. Explanation after the jump.
