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. ==Representation== A qutrit has three orthogonal basis states, or vectors, often denoted $|0\backslash rangle$, $|1\backslash rangle$, and $|2\backslash rangle$ in Dirac or bra–ket notation. These are used to describe the qutrit as a superposition in the form of a linear combination of the three states: :$|\backslash psi\backslash rangle\; =\; \backslash alpha\; |0\backslash rangle\; +\; \backslash beta\; |1\backslash rangle\; +\; \backslash gamma\; |2\backslash rangle$, where the coefficients are probability amplitudes, such that the sum of their squares is unity: : $|\; \backslash alpha\; |^2\; +\; |\; \backslash beta\; |^2\; +\; |\; \backslash gamma\; |^2\; =\; 1\; \backslash ,$ The qutrit's basis states are orthogonal. Qubits achieve this by utilizing Hilbert space $H\_2$, corresponding to spin-up and spin-down. Qutrits require a Hilbert space of higher dimension, namely $H\_3$. A string of ''n'' qutrits represents 3''n'' different states simultaneously. Qutrits have several peculiar features when used for storing quantum information. For example, they are more robust to decoherence under certain environmental interactions.〔A. Melikidze, V. V. Dobrovitski, H. A. De Raedt, M. I. Katsnelson, and B. N. Harmon, ''Parity effects in spin decoherence'', Phys. Rev. B 70, 014435 (2004) ((link ))〕 In reality, manipulating qutrits directly might be tricky, and one way to do that is by using an entanglement with a qubit.〔B. P. Lanyon,1 T. J. Weinhold, N. K.
