Last week I had the pleasure of going to Bristol in the UK to catch up with some good people and what's been going on in quantum networks.

I also got to present on a giant iMax screen. Quite surreal, a little intimidating, but also fun.

Not the spectacularly sunny weather we had been hoping to kick things off for the WQRN, but nonetheless an impressive view to wake up to on day 1.

By now, hopefully you can see that there is an ABSOLUTELY CRITICAL NEED for data center-scale #QuantumNetworks. There are also Big Science things you can do with a wide-area #QuantumInternet or with related technology such as LIGO's squeezing.
@Fraunhofer_IAF has developed single-mode GaSb #VECSEL with best-in-class output powers of up to 2.4 W, which enable #quantumfrequencyconversion as a low-noise pump source. This is an important step towards #quantumnetworks.
