If you’re interested in adiabatic dynamics and counterdiabatic driving + optimal control, please give it a read :))

After last week’s demonstration on an ion-trap quantum processor, Phasecraft showed the quantum simulation of a fermionic system on Google’s superconducting devices. This suggests that quantum computers are becoming practically useful for studying quantum many-body systems.

All the people who are totally fine with shooting down Russian fighter jets in NATO airspace
European Commission President Ursula von der Leyen told CNN on Sept. 24 that shooting down intruding jets should be considered if Moscow ignores other warnings.
