This article, prepared in conjunction with AFCEA’s Technology Committee, is the second in a series of three articles addressing quantum computing. The inaugural article, "The Current State of Quantum ...

A hundred years ago, quantum mechanics was a radical theory that baffled even the brightest minds. Today, it's the backbone ...

Mean-field theory and semiclassical methods constitute vital frameworks in contemporary quantum mechanics. By replacing the intricate web of particle interactions with an average or “mean” field, mean ...

At long last, a unified theory combining gravity with the other fundamental forces—electromagnetism and the strong and weak nuclear forces—is within reach. Bringing gravity into the fold has been the ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

In an effort to solve the riddle of why we have subjective conciousness, scientists have develop myriad theories, including ones involving the quantum realm. A new theory suggests that consciousness ...

The force we experience most intimately remains the most mysterious. Physicists understand how vast migrations of particles called photons light up our homes, and how swarms of “gluon” particles hold ...

Quantum physics is the “study of matter and energy at the most fundamental level.” Quantum technologies exploit the properties identified by quantum physics to provide new capabilities in computing, ...

Gravity, long the sovereign force in the cosmic hierarchy, may be little more than a statistical side effect a byproduct of entropy, not a fundamental interaction. That is the provocative assertion ...
