Phys.org / Quantum advantage reassessed: More realistic benchmarks for quantum algorithms

Quantum advantage refers to the point at which a quantum computer solves a clearly defined task faster or more efficiently than any classical computer—or makes it solvable in the first place. For many practical applications, ...

Phys.org / Genome study reveals centromeres as one of the fastest-changing regions in human DNA

A centromere is a specific region on a chromosome that ensures that, when a cell divides, the chromosome separates accurately so each new cell receives the correct amount of genetic material. Despite their essential role, ...
