That enables the calculation of both wave-ness and particle-ness with far more precision. By measuring the coherence in a system, in fact, it becomes possible to calculate a quantum object's level of ...

Light’s dual nature, manifesting as both wave-like and particle-like behaviour, is a phenomenon known as wave-particle duality and remains one of the most perplexing mysteries in quantum mechanics.

Humans have problems with quantum mechanics. We have excellent intuition about the motion of a tennis ball tossed in the air, but what about an electron trapped in a box? The tendency is to use the ...

Classically, light can be thought of in two ways: either as a particle or a wave. But what is it really? Well, the ‘observer effect’ makes that question kind of difficult to answer. So before we get ...

For nearly a century, “reality” has been a murky concept. The laws of quantum physics seem to suggest that particles spend much of their time in a ghostly state, lacking even basic properties such as ...

Surprising oil drop experiments suggest that the quantum world may not be as strange as advertised. For nearly a century, “reality” has been a murky concept. The laws of quantum physics seem to ...
