kvantumállapotot

kvantumállapotot is the Hungarian term for quantum state. A quantum state describes the condition of a quantum mechanical system. It contains all the information about the system that is knowable according to quantum mechanics. This information can include properties like energy, momentum, and spin. Unlike classical states, which can be precisely defined for all properties simultaneously, quantum states are often described using probability distributions. This means that certain properties may not have definite values until they are measured.

The concept of superposition is fundamental to quantum states. A system can exist in a combination of multiple possible states at the same time. For example, an electron's spin can be both "up" and "down" simultaneously until measured. The evolution of a quantum state over time is governed by the Schrödinger equation. When a measurement is performed on a quantum system, its quantum state "collapses" into one of the possible definite outcomes. This probabilistic nature of measurement is a key distinction between quantum and classical physics. Quantum states are represented mathematically by wave functions or state vectors.
