What is "qutrit"

n. (context computing English) A quantum unit of information that may take any of three states; the ternary equivalent of a qubit.

A qutrit is a unit of quantum information that exists as a superposition of three orthogonal quantum states.

The qutrit is analogous to the classical trit, just as the qubit, a quantum particle of two possible states, is analogous to the classical bit.
