The heart of quantum mechanics is the wave-particle duality: matter and light possess both wave-like and particle-like attributes. Typically, the wave-like properties are inferred indirectly from the ...

Quantum mechanics is a pillar of modern science and technology, and has benefited the human society for a century. The wave function, also known as the quantum state, is the description of a quantum ...

Physicists from the Canadian Institute for Measurement Standards are the first to measure a quantum mechanical wave function. And it only took 88 years from the formulation of Schroedinger’s equation!

Extremely cold atoms have been nudged to self-magnify their quantum states so they can be imaged in unprecedented detail. This could help researchers better understand what quantum particles do in odd ...

Just two years ago, with the advent of a technique called direct measurement, scientists discovered they could reliably determine a system’s wave function by “weakly” measuring one of its variables (e ...

Quantum mechanics has a concept called a “wave function.” It’s incredibly important because it holds all the measurable information about a particle (or group of particles) within it. In practice, the ...

It underpins the whole theory of quantum mechanics, but does it exist? For nearly a century physicists have argued about whether the wave function is a real part of the world or just a mathematical ...

Famously, at the quantum scale, particles can be in multiple possible locations at once. A particle’s state spreads out like a wave, peaking where the particle is likely to be found. When you measure ...
