1. A media-defined optical logic circuit capable of performing a logical operation, the circuit comprising: a set of polyhedral prisms physically arranged such that at least one surface of each prism of the set of polyhedral prisms is adjacent to a distinct surface of another prism of the set of polyhedral prisms, where a first prism of the set of polyhedral prisms comprises a first embedded quantum dot of a set of quantum dots, a first prism-input surface, and a first prism-output surface, such that a sufficiently energetic first photonic signal received through the first prism-input surface is capable of exciting the quantum dot to produce light capable of being emitted through the first prism-output surface as a second photonic signal, where the first prism-output surface is adjacent to a second prism-input surface of a second prism of the set of polyhedral prisms, such that light is capable of passing from the first prism to the second prism along a path between the first prism-output surface and the second prism-input surface, where the logic circuit is configured to respond to a set of photonic circuit-input signals, received from external light sources, by emitting a set of photonic circuit-output signals, where the set of photonic circuit-output signals represents a binary value derived by performing the logical operation upon a binary value represented by the set of photonic circuit-input signals, where the arrangement of the set of polyhedral prisms allows the circuit to receive the set of photonic circuit-input signals through input surfaces of one or more circuit-input prisms of the set of polyhedral prisms, and where the arrangement of the set of polyhedral prisms allows the circuit to emit the set of circuit-output signals through circuit-output surfaces of one or more circuit-output prisms of the set of polyhedral prisms.
