01
Quantum State
A quantum state contains the information required to predict probabilities for measurements. States are represented mathematically in a Hilbert space.
02
Schrödinger Equation
iℏ ∂|ψ⟩/∂t = H|ψ⟩
The Schrödinger equation governs the time evolution of quantum states in nonrelativistic quantum mechanics.
03
Uncertainty
Δx Δp ≥ ℏ/2
The uncertainty relation is a mathematical consequence of noncommuting quantum observables and is not simply a statement about imperfect measurement instruments.
04
Entanglement
Entanglement describes quantum states of composite systems that cannot be represented as independent states of their components.
