Casimir-effect based tunnel transistor utilizing graphene

A quantum system comprising:

• a plurality of quantum devices individually including:
• a fixed source electrode comprising a first graphene material;
• a quantum dot configured to localize a single electron, wherein the quantum dot and the fixed source electrode are disposed within a common vacuum to define a tunneling gap;
• and
• a modulator configured to emit electromagnetic signaling within a particular frequency range, wherein the first graphene material is tuned to vary a surface conductivity of the first graphene material in response to the electromagnetic signaling in a first frequency range, wherein varying the surface conductivity of the first graphene material increases a Casimir force across the tunneling gap to increase an electron tunneling probability across the tunneling gap without physical movement of the fixed source electrode;
• a plurality of mediator quantum dots individually positioned between a pair of adjacent quantum dots of the plurality of quantum devices;
• and
• a mediator bus comprising a plurality of mediator bus quantum dots, wherein the mediator bus links pairs of adjacent quantum dots of the plurality of quantum devices through the plurality of mediator quantum dots, wherein the plurality of mediator quantum dots and the mediator bus enable entanglement propagation between non-adjacent qubits stored in the plurality of quantum devices.
