An “echo” that arrives before you finish speaking sounds like a glitch. In quantum hardware, that kind of self-interference ...

Henry Yuen is developing a new mathematical language to describe problems whose inputs and outputs aren’t ordinary numbers.

“The theoretical framework we developed explains how quasiparticles emerge in systems with an extremely heavy impurity, ...

Physicists at Heidelberg University have developed a new theory that finally unites two long-standing and seemingly ...

In the everyday world, governed by classical physics, the concept of equilibrium reigns. If you put a drop of ink into water, it will eventually evenly mix. If you put a glass of ice water on the ...

Quantum computer research is advancing at a rapid pace. Today's devices, however, still have significant limitations: For example, the length of a quantum computation is severely limited—that is, the ...

For decades, cobalt has served as a benchmark ferromagnet. Its crystal structure and magnetic properties have been extensively documented. However, the new findings show that cobalt hosts a rich ...

Quantum mechanics replaced the clockwork certainty of classical physics with something far stranger: a framework in which particles do not follow single, predictable paths but instead exist as clouds ...

In 1905, a 26-year-old patent clerk named Albert Einstein looked at the universe and discovered that time was not what we thought it was. It was not linear. For centuries, everyone assumed the same ...

When quantum computing makes headlines, it’s typically one of two stories. The first is a promise: incredible power is coming. Engineering marvels from Silicon Valley or China, boasting quantum bits ...
