American and Australian researchers have discovered that, when a supercooled gas is cooled even further, it enters a phase transition where a number of atoms gather into a Bose-Einstein condensate. Depending on the gas and its temperatures, the atoms begin to spin rapidly, forming a quantum tornado. This allows scien... |

The building block of quantum computers is the qubit, a unit of quantum information that can be made up of either atoms or photons. Atoms have a long coherence time, so they're used as "stationary" qubits, the nodes of the network, while photons are the "flying" cubits, the quantum channels connecting the nodes... |
