Qutrit
UNIT OF QUANTUM INFORMATION THAT EXISTS AS A SUPERPOSITION OF THREE ORTHOGONAL QUANTUM STATES; ANALOGOUS TO THE CLASSICAL TRIT, JUST AS THE QUBIT, A QUANTUM PARTICLE OF TWO POSSIBLE STATES, IS ANALOGOUS TO THE CLASSICAL BIT
Quantum trit; Quantum trinary digit; Quantum ternary digit
A qutrit (or quantum trit) is a unit of quantum information that is realized by a 3-level quantum system, that may be in a superposition of three mutually orthogonal quantum states.
