A qutrit is a quantum system that can exist in a superposition of three distinct states, as opposed to a qubit, which can exist in a superposition of two states. The term "qutrit" is derived from "quantum trit," where "trit" refers to a digit in base-3 numeral systems, similar to how "qubit" references a binary digit in base-2 systems.
