Now, Philippe Grangier, from @InstitutOptique on Recent progress on continuous variable quantum cryptography #LTQI
@InstitutOptique Sadly, I’m on low battery, so I don’t know how long I’ll be able to livetweet Philippe Grangier’s talk #LTQI
@InstitutOptique Philippe Grangier:«We have very good proofs for that, many of them don by @letonyo»
@InstitutOptique Philippe Grangier. continuous variable (CV) coherent state cyrptography works well. It is only telecom components. It should be everywhere but it is not ? Why ? #LTQI
@InstitutOptique Philippe Grangier: Market inhibitors: High cost, Lack of network integration, of crypto integration and standard. (slide from Andrew Shields). #LTQI
Philippe Grangier: to reduce the cost, do it with integrated photonic. But with integrated optics, the cycle going from designing the chip to understanding why it doesn't work takes a very long time. #LTQI
Philippe Grangier: Now coherent optical receiver (aka heterodyne detectors) are standard, but they are not shotnoise limited. Telecom engineers don't care about shotnoise #LTQI
