Unsurprising but also not the best thing to read the day of an ERC interview 🥲

@quantumjournal A bonus for the lovers of the two-point measurement (TPM) scheme. If a state-independent scheme satisfies (= certifies) the Jarzynski equality, then it essentially coincides with the TPM scheme. "Essentially" = with some extra assumptions; see the paper for full classification.

@quantumjournal If the measurement scheme is allowed to depend on the state, then (A1) & (B) become compatible. However, (A1), (A2), & (B) remain incompatible. Only the scheme based on measuring the Heisenberg operator of work satisfies (A1) & (A2). All other known schemes fail at (A1) & (A2).

Ever thought about how to certify the law of conservation of energy? Turns out it's tricky in the quantum regime! Read on for a brief explainer of the main points. Better yet, check out our paper for the full story. I'm very happy it's finally published in @quantumjournal 🧵

Which was the first quantum paper that used the word "information"? Was it Holevo 1973?

@AlhambraAlvaro Especialmente cuando casi todas las publicaciones de la persona provienen de grandes proyectos de "colaboracion" con miles de coautores.

Ningun cientifico serio deberia prestar demasiada atencion a este tipo de ranking (basado en citas), y es una pena que tanto instituciones como periodistas caigan en ello. El mismo entrevistado lo dice al principio.

🔴El científico 'más importante' de España vive en Santander, pero casi nadie le conoce. @fmatorras, catedrático e investigador del IFCA (@CSIC-@unican), lidera el 'ranking' de científicos españoles en Google Scholar. ✍🏽@josePichel (@elconfidencial) 📲elconfidencial.com/tecnologia/cie…
