Modular Quantum Resource State System

A method comprising:

• receiving, on a first plurality of optical interconnects, qubits of a plurality of seed entangled states, the plurality of seed entangled states further comprising other qubits on other optical interconnects that are coupled to one or more external devices, the first plurality of optical interconnects being coupled to a plurality of resource state interference circuits in a non-cryogenic structure;
• interfering, on the plurality of resource state interference circuits, the qubits of the plurality of seed entangled states;
• coupling, on a second plurality of optical interconnects, interfered qubits from the plurality of resource state interference circuits in the non-cryogenic structure to a plurality of detectors in a cryogenic structure;
• generating, on the plurality of detectors, resource state readout data from the interfered qubits;
• and
• determining, on control circuitry, that a plurality of resource entangled states comprises the other qubits that are on the other optical interconnects based on the resource state readout data, the plurality of seed entangled states and the plurality of resource entangled states being different types of entangled states.
