Logika kwantowa.
A Quantum Gate is the equivalent of a classical logic gate (like AND, OR, NOT) but adapted for the principles of quantum mechanics. Unlike classical gates, which are often dissipative and irreversible, all quantum gates (except for measurement) are Unitary and Reversible. They operate on superpositions of states, allowing for the parallel transformation of quantum information. Mathematically, a gate is a unitary operator $U$ that acts on a state vector $|\psi angle$, such that the total probability is conserved ($U^{\dagger}U = I$).
