This document.

3.1.1 multiscale simulation

Simulations conducted at different scales, including quantum, microscopic, mesoscopic, and macroscopic scales.

3.1.2 quantum scale

The motion and interaction of matter are governed by the laws of quantum mechanics, ranging from the Planck length (approximately 1.616 × 10^-³^5 m) to the atomic level.

The size range (approximately 10-9m).

Note 1.The quantum scale is the most fundamental scale level in the material world. The objects of study at this scale include atoms, electrons, and smaller particles (such as quarks).

Note 2.The core characteristics of the quantum scale include quantum superposition (a particle simultaneously existing in multiple states, such as Schrödinger's cat's "both dead and alive" state), quantum entanglement, and quantum entanglement.

Entanglement (multiple particles forming an interconnected whole, where a change in the state of one particle instantly affects another, regardless of distance), wave-particle duality (particles are both...

It exhibits both the locality of particles and the dispersion of waves, such as the interference fringes formed when electrons pass through the double slits.
