Quantum physics studies particles smaller than atoms.

Particles can behave like waves and particles at the same time.

Quantum entanglement means particles can be connected over long distances.

Energy levels in atoms are quantized—particles jump between levels.

Quantum mechanics explains how electrons orbit atoms.

Uncertainty principle says we can’t know a particle’s position and speed exactly at the same time.

Quantum computers use quantum bits (qubits) to perform calculations.

Quantum tunneling lets particles pass through barriers they shouldn’t be able to.

Photons are particles of light studied in quantum physics.

Quantum physics is the basis for technologies like lasers and semiconductors.
