Claim 11:
12. An apparatus, comprising:
a plurality of logical quantum nodes, the logical quantum nodes including an input quantum node, a hidden quantum node, and an output quantum node, wherein i) each logical quantum node, of the plurality of logical quantum nodes, is configurable to switch between being in a clamped state and an unclamped state and ii) the plurality of logical quantum nodes represent information bearing degrees of freedom;
a plurality of control quantum nodes, each control quantum node, of the plurality of control quantum nodes, is configurable to switch between being in the clamped state, the unclamped state, or an initial default state, wherein
the plurality of control quantum nodes represent non-information bearing auxiliary degrees of freedom and control interactions of the logical quantum nodes with an environment modelled by a thermal bath;

a plurality of quantum node couplers, each coupler being configured to couple a pair of quantum nodes, wherein:
the couplers couple at least the input quantum node and the hidden quantum node to a first control quantum node and couple at least the hidden quantum node and the output quantum node to a second control quantum node to control interactions of the input quantum node, hidden quantum node, and output quantum node with the environment;

wherein one or more of the plurality of control quantum nodes comprise a Quantum Governor node that either:
manipulate interactions between the hidden quantum node and the input quantum node or output quantum node using the coupler that couples the input quantum node and the hidden quantum node to the first control quantum node and the coupler that couples the hidden quantum node and the output quantum node to the second control quantum node, wherein the plurality of couplers comprises couplers that couple the input quantum node and the output quantum node to the hidden quantum node to allow for direct interactions between the hidden quantum node and the input quantum node or output quantum node; or
completely determine interactions between the hidden quantum node and the input quantum node or output quantum node using the coupler that couples the input quantum node and the hidden quantum node to the first control quantum node and the coupler that couples the hidden quantum node and the output quantum node to the second control quantum node, without allowing for direct interactions the hidden quantum node and the input quantum node or output quantum node.
