Can UKRI funded research be published in Physical Review?

For many of my colleagues in low-energy nuclear physics, Physical Review C is the default journal for most of their research.  The default ...

Powerful quantum computers in years not decades, says Microsoft

It says a new chip it has created could end up being as important a breakthrough as the semiconductor.

Solving coupled non-linear schrödinger equations via quantum imaginary time evolution - The European Physical Journal Special Topics

Coupled non-linear Schrödinger equations are crucial in describing dynamics of many-particle systems. We present a quantum imaginary time evolution (ITE) algorithm as a solution to such equations in the case of nuclear Hartree-Fock approach. Under a simplified Skyrme interaction model, we calculate the ground state energy of an oxygen-16 nucleus and demonstrate that the result is in agreement with the classical ITE algorithm. We examine bottlenecks and deficiencies in the quantum algorithm and suggest possible improvements.

"In the late 1950s, theorists in high-energy fundamental-particle physics in Cambridge moved out of the Cavendish Laboratory away from experiment into the Department of Applied Mathematics and Theoretical Physics (DAMTP), and major new discoveries in this area ceased to be made in Cambridge."
