News Quantum cryptography stretches 100 kilometres

From New Scientist:

Communications protected with the complete security of quantum cryptography are now possible over an ordinary 100-kilometre fibre optic cable, thanks to sophisticated photon detection equipment developed by UK researchers.

A team from Toshiba Research Europe, based in Cambridge, UK, has developed a quantum photon detector capable of significantly reducing the amount of random noise picked up as the super-secure cryptographic keys are generated. This boosts the fibre optic distance over which quantum cryptography is feasible

I wonder if Cheese has had a hand in this.....

 

I do indeed!

I'm not allowed to say much but it's the folks in lab next to mine who've been working on this (and at 1.5µm too!).

Rob.

 

all sounds a bit complicated
