Practical applications of quantum computing are currently limited by the number of qubits
that can be set with reasonable fidelity for each system. Therefore, a distributed quantum
computing system with multiple quantum computers coherently connected is highly
demanding. To realize the inter-node communication of quantum information, the software
interface, Quantum Message Passing Interface (QMPI), leveraging the framework built for
classical MPI but taking advantage of quantum teleportation to communicate between …

Quantum computers today are noisy and limited in the number of qubits that can be set with
reasonable fidelities and gate times for each system. Since the current limit on the number of
qubits is difficult to surpass, it is expected that the future of quantum computing will lie in
connecting different quantum computers together to form a quantum network, each with its
own limitations. Herein lies the field of distributed quantum computing optimized for large-
scale communication. One such system that has been designed is the Quantum Message …
