Upcoming experimental tests of gravity’s quantumness aim to resolve one of the biggest questions in physics, but theorists ...

Theoretical chemists have developed a theory that can predict the threshold at which quantum dynamics switches from 'orderly' to 'random,' as shown through research using large-scale computations on ...

The firm says it has solved a problem on a quantum processor faster than a classical computer, and is optimistic about future ...

A team of international physicists has brought Bayes’ centuries-old probability rule into the quantum world. By applying the ...

Quantum mechanics is simultaneously beautiful and frustrating. Its explanatory power is unmatched. Armed with the machinery of quantum theory, we have unlocked the secrets of atomic power, divined the ...

If you picture an electron breaking free from a solid, the process seems simple. Give it enough energy, and it should blast ...

For over 100 years, two theories have shaped our understanding of the universe: quantum mechanics and Einstein’s general relativity. One explains the tiny world of particles; the other describes ...

We’re celebrating 180 years of Scientific American. Explore our legacy of discovery and look ahead to the future. This year is the International Year of Quantum Science and Technology, according to ...

A hidden world of quantum metrologists ensure that everyday devices perform safely and correctly, but their work is never done ...

Few of Albert Einstein’s sayings have been as widely quoted as his remark that God does not play dice with the universe. People have naturally taken his quip as proof that he was dogmatically opposed ...

This post is in response to Quantum Effects In the Brain By Robert Lanza M.D. In his 2019 New York Times opinion piece entitled, “Even Physicists Don’t Understand Quantum Mechanics. Worse, they don’t ...
