What is quantum physics? Put simply, it’s the physics that explains how everything works: the best description we have of the nature of the particles that make up matter and the forces with ...

Quantum mechanics YAY Media AS/Alamy Quantum mechanics is the best tool we have to understand how the universe works on its smallest scales.

Quantum physics is the best description we have of the nature of the particles that make up matter and the forces with which they interact. But quantum physics also presents a conundrum about the ...

Quantum field theory marries the ideas of other quantum theories to depict all particles as “excitations” that arise in underlying fields. The British physicist Paul Dirac started the ball ...

Quantum lidar could help driverless vehicles spot bright objects Driverless cars can use lasers to sense objects, but reflected light from nearby vehicles or bright sunlight can interfere.

Devised in 1935 by the Austrian physicist Erwin Schrödinger, this thought experiment was designed to shine a spotlight on the difficulty with interpreting quantum theory . Quantum theory is very ...

The famous double-slit experiment brings into question the very nature of matter. Its cousin, the quantum eraser experiment, makes us question the very existence of time – and how much we can ...

Quantum theory, which accurately describes the physics of the very small, and general relativity, developed by Albert Einstein, which describes the physics of the enormously large.

This is the quantum uncertainty principle. It connects not just position and momentum, but energy and time and a whole host of other pairs of quantities.

Jul 11, 2022 · When talking about quantum physics, people will often nonchalantly say that particles can be in two places at once. Physicist Sabine Hossenfelder explores what is actually going on
