One of the first steps toward becoming a scientist is discovering the difference between speed and velocity. To nonscientists, it’s usually a meaningless distinction. Fast is fast, slow is slow. But ...

Two RIKEN physicists have established new theoretical limits for experimentally measurable quantities by viewing solids ...

Interacting system: A diagram of the researchers' four-qubit superconducting quantum chip. (Courtesy: Y Yu) Researchers at Nanjing University in China have used a superconducting quantum chip to ...

Quantum bounds revealed: RIKEN researchers derived limits for three measurable parameters in solids, offering fresh insights into quantum material behavior. Mapping quantum state space: The study uses ...

A new quantum-inspired algorithm is reshaping how scientists approach some of the most complex materials known, enabling ...

We always enjoy [FloatHeadPhysics] explaining any math or physics topic. We don’t know if he’s acting or not, but he seems genuinely excited about every topic he covers, and it is infectious. He also ...
