More than a century before quantum mechanics was born, Irish mathematician William Rowan Hamilton stumbled onto an idea that would quietly foreshadow one of the deepest truths in physics. While ...

Right now, quantum computers are small and error-prone compared to where they’ll likely be in a few years. Even within those limitations, however, there have been regular claims that the hardware can ...

There is more research into the Dwave Systems quantum annealing adiabatic system (503 qubit version). Researchers from UCL (University College of London) and USC (University of Southern California) ...

For the classical wave equation the map from initial data to Friedlander?s radiation field is an isometry in energy spaces. I will explain the limitations of classical scattering theory, in the ...
