Beating the Ramsey limit on sensing with deterministic qubit control
Ramsey interferometry1 has been long established as the most sensitive measure of a qubit’s frequency2. In a Ramsey measurement, a qubit is prepared in a superposition of energy states, allowed to evolve freely and acquire phase, and then…

Gravity is Result of Computational Process within Our Universe, Physicist Says
University of Portsmouth physicist Melvin Vopson proposes a new way to think about gravity — not just as a pull, but as something that happens when the Universe is trying to stay organized.
This artist’s impression shows the evolution of…
