Integrating Q1RAM into Quantum Teleportation and Superdense Protocols: A Framework for Large-Scale Quantum Communications

Quantum teleportation and superdense coding are two different protocols that were developed to transmit a limited number of qubits and two classical bits, respectively. Therefore, they are inefficient for transmitting messages containing a massive number of individual qubits or classical bits. Thus, it is necessary to scale up these two protocols in larger systems to enable them to transmit massive messages. To achieve this goal, it is essential to integrate each of these two protocols within architectures that contain a quantum main memory that functions as a buffer capable of storing both quantum and classical data and managing a massive amount of data efficiently during transmission operations. Q1RAM is a cutting-edge quantum main memory and the fastest quantum main memory available, as it has a time complexity of $$O(1)$$ for accessing memory locations. In this paper, two architectural schematics are proposed based on integrating Q1RAM as a core component with the quantum teleportation and superdense coding protocols. The first architectural scheme is developed to scale up the quantum teleportation protocol, making it efficient for transmitting massive messages of separable individual qubits. The second architectural schema is proposed, consisting of two Q1RAM chips, two quantum processing units, two of the classical RAMs, and a quantum gateway. This proposed schema is developed to scale up the superdense coding protocol so that it can transmit massive classical messages containing large amounts of data. The experimental simulation results validate the architectural schematics for scaling up the quantum teleportation and the superdense coding protocols for large-scale quantum communications.
