Theories of quantum mechanics predict that some particles can exist in superpositions, which essentially means that they can be in more than one state at once. When a particle's state is measured, ...

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 ...

The biggest open problem in the foundations of physics is that Einstein’s theory of gravity, General Relativity, does not ...

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 ...

Last summer saw security giant Palo Alto Networks update its firewall operating system with quantum-optimized hardware to deliver high‑throughput processing of post-quantum cryptography (PQC). The ...

The Colorado Quantum Incubator, a collaborative facility in Boulder’s Flatiron Park corporate campus, is launching what it ...
