1. A method of operation in a computational system that comprises both a specific instance of a quantum processor and at least one digital processor communicatively coupled to one another, the quantum processor comprising a plurality of qubits, wherein qubits of the plurality of qubits are communicatively couplable to one another, the method comprising:
receiving, by the at least one digital processor, a first submitted problem;
modifying, by the at least one digital processor, the first submitted problem to compensate for communicative couplings between the qubits of the plurality of qubits induced by non-idealities of the specific instance of the quantum processor upon programming the first submitted problem thereon;
producing, by the at least one digital processor, a problem graph representation of the modified first submitted problem;
embedding, by the at least one digital processor, the problem graph representation of the modified first submitted problem in a hardware graph of the quantum processor; and
generating solutions to the first submitted problem via the quantum processor with the problem graph representation of the modified first submitted problem embedded therein.
