Physicists Use Quantum Mechanics to Pull...

Together, Charles Bennett and Gilles Brassard figured out how to use the laws of quantum physics to keep secret messages safe from eavesdroppers. Their efforts have earned them one of the highest awards in computing and a $1 million prize. On this episode of The Quanta Podcast, h ... Show More

Is string theory the one true “theory of everything?” Some physicists swear it’s a fundamental ingredient of nature. Others wish it would just go away. On this episode of The Quanta Podcast, host Samir Patel speaks with columnist Natalie Wolchover about the mathematical developme ... Show More

For decades, mathematicians have struggled to understand matrices that reflect both order and randomness, like those that model semiconductors. A new method could change that.The story New Physics-Inspired Proof Probes the Borders of Disorder first appeared on Quanta Magazine. 

An examination of some more advanced concepts of quantum mechanics, focusing on describing Dirac's bra-ket formulation of quantum theory. I discuss the formulation of quantum mechanics in terms of vectors in Hilbert spaces, Hermitian operators as corresponding to observables, ort ... Show More

<p>Aristotle argued almost 2,400 years ago that a perfect vacuum could never exist. Today, the concept of nothingness figures at least implicitly into almost every theory of modern physics. In this episode closing out season 2 of “The Joy of Why,” the theoretical physicist Isabel ... Show More

<p><span style="font-weight: 400">Quantum field theory may be the most successful scientific theory of all time, predicting  experimental results with stunning accuracy and advancing the study of higher dimensional mathematics. Yet, there’s also reason to believe that it is missi ... Show More

This month’s episode of the Physics World Stories podcast looks in depth at the science behind the 2022 Nobel Prize for Physics and the technologies that are emerging as a result. Alain Aspect, John Clauser and Anton Zeilinger shared this year’s award “for their experiments with ... Show More

<p>Quantum mechanics and general relativity are two of the most successful theories of science ever, but they don&apos;t necessarily fit together. Learn why physicists are trying so hard to discover a quantum theory of gravity, and why it&apos;s been such a challenge.<br/><br/>Fo ... Show More

Quantum mechanics is full of weird findings – for example, that systems widely separated can somehow still be correlated, and that a system may be in two different possible states at the same time. Entanglement and superposition, among other phenomena, have prompted debate since ... Show More

The secret to making a qubit for future quantum computers might depend on knowing how to tie knots in unusual materials, argues the physicist Charlie Marcus. The post Charlie Marcus Knows That Quantum Facts Aren’t Complicated first appeared on Quanta Magazine
