Quantum mechanics has fundamental speed limits—upper bounds on the rate at which quantum systems can evolve. However, two groups working independently have published papers showing for the first time that quantum speed limits have a classical counterpart: classical speed limits. The results are ...

Though his work upended what was thought to be a fundamental truth of black holes, Hawking radiation actually did some reconciliation. His work connected two conflicting concepts in theoretical physics: quantum mechanics and the theory of relativity. “Those are the two pillars on which physics now rests, ...

"Instead, we use light as a tool to facilitate a quantum mechanical effect. And that creates the new kind of ... The rules of quantum mechanics dictate that every time an atom changes its state, the atom must pay a price in the form of energy, just like climbing a hill. While a smooth transition may appear as a ...

"We learned that Einstein's theory is incomplete. In fact, Einstein himself was looking for a theory of everything that would unite quantum mechanics, atomic physics, with black holes. And so what Hawking did was he showed that black holes are not really black, overturning decades of thinking," Kaku said.

The tiniest levels of the universe are governed by the laws of quantum mechanics. Here things start to get very weird and counterintuitive. Units of information in the realm of quantum mechanics are called qubits. Headrick studies the quantum entanglement of qubits, a very strange phenomenon unique to ...

What could be described as a physics super-group has succeeded in setting the stage for the development of a quantum mechanical field called ... that a carbon-based magnet can carry waves of quantum mechanical magnetisation – units known as magnons – and convert them into electrical signals.

Enormous disks of stars or debris can operate under the same rules as subatomic particles, changing based on the Schrodinger equation, which physicists use to model quantum-mechanical systems. Viewing space ... And instead, I get this equation, which is really the cornerstone of quantum mechanics.

The twentieth century gave birth to two of the most important Physics theories of nowadays: Special/General Relativity and Quantum Mechanics. These two theories have accompanied humanity in the questions of what is space, what is time and what is matter; they have taught us to characterize these ...

The wisdom of experience goes a long way. That may hold especially true in complex topics such as quantum mechanics. When studying the science that explores properties of molecules, atoms and their constituents — electrons, protons and neutrons — along with other, more esoteric particles, any leg up ...

University of British Columbia researchers have found a new system that could help yield 'warmer' quantum technologies. Quantum technologies such as quantum computers have the ...

Schrodinger's equation is a fundamental equation of quantum mechanics that describes how particles behave at the subatomic level. Caltech researchers were astonished to learn, however, that the same equation popped up when they modeled the behavior of self-gravitating astrophysical disks.
