+A ‘Quantum Limit’ smashed?

Increases number of phases detectable Error rates four times lower than previously thought to be a

‘quantum limit’

If correct, implications for communication Higher speed Less power Fewer errors

+Better than Diamonds in QC?

+Gigabit wireless internet and beyond!

802.11ac and 802.11ad Up to 7 gigabits / second 3x improvement in # of MIMO bit streams 802.11ac is specialized to the 5 GHZ band

Lower power consumption Wide area

802.11ad is for both for 2.4 and 5 GHZ band More of a bluetooth on steroids

What of cell? LTE Advanced
