Shortly, at 4.30 PM, we are going to host @ CTP PAS Oskar Leimkuhler from University of California, Berkeley who is is going to talk about possible exponential speedups that quantum computers offer for quantum chemistry (based on .

Super nice work of Matteo Scandi and.@AlhambraAlvaro.about rigourous thermalization in many body systems!.
New paper today! Very excited to announce we obtain, from first principles, a quantum master equation that both applies in the many-body regime and provably converges to the exact Gibbs state:

I am very happy that our joint work with Marcin Kotowski on extremal jumps of circuit complexity in time evolutions generated by random Hamiltonians has been recently published in JHEP: :).

New paper out! We study time evolution of circuit complexity of unitaries generated by GUE Hamiltonians. We prove a surprising behavior of complexity - namely that undergoes a sudden jump from 0 to nearly a maximal allowed value (d^2, in dim d) .(1/n)

I am happy to share that our paper on efficient measurement schemes for quantum chemistry applications was recently published in npj Quantum Information . Many thanks to Asia Majsak and Dan McNulty for great work!.

npj Quantum Information - A simple and efficient joint measurement strategy for estimating fermionic observables and Hamiltonians
Looking for an alternative to fermionic (matchgate) classical shadows that is easier to implement on current hardware? In two papers.that appeared today we use theory of measurement incompatibility to propose an alternative. (1/5)

Last week I had a very productive visit to the group of @efgalvao in Braga.I enjoyed beautiful weather,nice discussions on partial distinguishability in photons,and gave a talk on recent advances on BosonSampling. It was my first official trip within the @EPIQUEquantum project :)

W tym tygodniu odwiedzam @Piotr_Fizyk i Darka Chruścinskiego w Toruniu. Dziś opowiadałem matematykom o symulowaniu POVMów przez pomiary rzutowe. W czwartek daję kolokwium. Jest trochę stresu, ale za to kawiarnie w Toruniu - wyśmienite :)

Najlepiej więc mieć zdrowy dystans do tego typu ogłoszeń. Na solidny postęp w technologii komputerów kwantowych nakłada się rywalizacja PRowa między korporacjami (jak również geopolityczna). Warto korzystać z dobrych źródeł, np. czy @DulwichQuantum.

(ale nie testują na nim żadnych bramek czy operacji). Jeśli wczytać się w recenzje pracy, komentarz edytorski, oraz stanowisko samego czasopisma - jest tu dużo sceptycyzmu nawet co do tego czy mamy obserwację pojedynczego topologicznego qubitu

W press release mowa o procesorze 8 qubitowym (bez eksperymentalnych danych potwierdzających jego działanie).W tym samym czasie (19.02) ukazuje się praca w Nature, która daje wskazówkę, że "być może" mają jeden qubit topologiczny.
