1. A system for performing a non-classical computation, comprising:
at least one host material comprising at least one organic molecule; and
a plurality of dopant molecules contained in the at least one host material, wherein:
each dopant molecule comprises a qubit having at least a first qubit state and a second qubit state;
each dopant molecule is associated with an electronic energy level structure that includes a triplet electronic manifold;
the triplet electronic manifold comprises a first triplet state, a second triplet state, and a third triplet state;
the first qubit state comprises a first linear combination of the first triplet state, the second triplet state, and the third triplet state;
the second qubit state comprises a second linear combination of the first triplet state, the second triplet state, and the third triplet state;
the first qubit state is different from the second qubit state;
the first qubit state or the second qubit state has a lifetime of at least 25 milliseconds (ms) at a temperature between 4 Kelvin (K) and 20 K; and
at least one dopant molecule is coupled to at least one other dopant molecule by an electronic dipolar coupling interaction having a dipolar coupling strength of at least 1 kilohertz (kHz).
