Are Quantum Fluctuations Real?

But although they're invisible, like most things in the quantum world, they subtly influence the real world. These quantum fluctuations produce randomly fluctuating electric fields that can affect electrons, which is how scientists first indirectly demonstrated their presence back in the 1940s.

Do quantum fluctuations exist?

In July 2020, scientists reported that quantum vacuum fluctuations can influence the motion of macroscopic, human-scale objects by measuring correlations below the standard quantum limit between the position/momentum uncertainty of the mirrors of LIGO and the photon number/phase uncertainty of light that they reflect.

Why do quantum fluctuations happen?

The scientific term for these bubbles is Quantum fluctuations. Unlike the classic case, where a change in the temperature is responsible for the bubbles, in the quantum case the bubbles arise due to the uncertainty principle which is one of the basic rules in quantum physics.
