“The Forbidden Quantum Adder”

As a fan and follower @AndreasAtETH, since your seminal talks in Munich 2004-5, those numbers look small compared to the immense value, impact, and creativity of your interdisciplinary work. You disrupted the intellectual paths of many always for better, thanks @QuantumFlagship https://twitter.com/andreasateth/status/1353281477379821570

Esta noticia confirma, contra prejucios de Francia e inversión de riesgo, el auge de las tecnologías cuánticas en Europa y el mundo. Son decisiones geopolíticas visionarias por el empleo y promoción del talento @cientificospe @QuantenTech @QuantumFlagship

Le Président Macron a augmenté le budget annuel jusqu‘à 200 millions Euro en technologies quantiques, en provenant de 1,8 milliard d‘euros à 5 ans. Chapeau contre les prejugés de la mentalité francaise et le risque @QuantenTech @BMBF_Bund @QuantumFlagship

I will give a plenary talk at International Scientific Conference, Lima, Peru, 30 Jul 2021, Bicentennial celebrations. I will speak on Quantum Computing and Entrepreneurship, and how emergent economies may profit and join Industry 4.0 @cientificospe @CientificoenEsp @QuantenTech https://twitter.com/modestomontoya/status/1350286457257254917

@jenseisert I get the point! By chance I have recently studied your old masterpieces about Gaussification protocols to see whether pre-Gaussification may enhance teleportation fidelity of non-Gaussian CV states when using Gaussian resources (TMS states) 😉

@qmisanz Actually, the channel is Gaussian-preserving, it is non-interacting quantum dynamics. But the state is non-Gaussian, having a memory of past interactions.

@jenseisert So this means that the fixed point of the dynamics is in general Gaussian even when the channel is not Gaussian-preserving. Is not a necessary condition the injectivity of the dynamical channel?

In 2008 I first stared at proof techniques that show that quantum many-body systems would tend to relax following #nonequilibrium dynamics and would "Gaussify" in time. Even though the precise mechanism here is somewhat different, to see this is pleasing.

Welcome Julia, great to see that we are sharing the same mission: Building quantum computers for a better world! https://twitter.com/meetIQM/status/1351114237276532740

Será un gusto volver a vernos en persona en el ECI del Bicentenario de invierno. Les contaré los últimos avances en la computación cuántica y tecnologías cuánticas, y también sobre la promoción del talento, la creatividad, startups y el emprendimiento empresarial @cientificospe https://twitter.com/modestomontoya/status/1350286457257254917
