Quantum Teleportation Between Distant Matter Qubits: First Between Atoms 1 Meter Apart Date: January 23, 2009 Source: University of Maryland Summary: ...

And it did so by cooling a 30-meter-long aluminum wire to just a few milliKelvin. Because the qubits are so easy to control, the experiment provides a new precision to these sorts of measurements.

If the excitons remained coherent for relatively long periods of time, they should be more likely to reach their destination and therefore boost the performance of the quantum meter. What the ...
