Physicists Use Quantum Mechanics to Pull...

It’s been difficult to find important questions that quantum computers can answer faster than classical machines, but a new algorithm appears to do it for some critical optimization tasks.The story Quantum Speedup Found for Huge Class of Hard Problems first appeared on Quanta Mag ... Show More

“Memory” means many things to many people, and in many fields. We tend to understand memory to be a phenomenon that happens primarily in the brain, but in recent years, researchers have understood memory as a physical phenomenon that can occur in plenty of systems. On this episod ... Show More

The climate is changing. So is the way we understand the climate. On this week's episode, contributing writer Zack Savitsky joins host Samir Patel to discuss his recent reporting on the rich history and uncertain future of climate modeling, the field of science that blends math, ... Show More

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

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 Ga ... Show More

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 missing something. Steven Strogatz spea ... Show More

The 2022 Nobel Prize for Physics celebrated research that is underpinning a tech transformation 

Quantum mechanics and general relativity are two of the most successful theories of science ever, but they don't necessarily fit together. Learn why physicists are trying so hard to discover a quantum theory of gravity, and why it's been such a challenge.For ad-free episodes and ... 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
