Quantum walks sound abstract, but they sit at the center of a very concrete race: who will harness quantum mechanics to solve problems that overwhelm today’s most powerful supercomputers. Instead of ...

Albert Einstein’s theory of gravity, general relativity, is famously incomplete. As proven by physics Nobel laureate Roger Penrose, when matter collapses under its own gravitational pull, the result ...

Main ideas of the article are further expanded on in this online lecture by the author. Faced with this problem, I realized that the ultraviolet radiation he described might be explained using quantum ...

Theoretical physicists in the US have discovered a "speed limit" on the time taken for quantum information to spread through ...

Repulsive gravity at the quantum scale would have flattened out inhomogeneities in the early universe First light The cosmic microwave background, as imaged by the European Space Agency’s Planck ...
