To bring the quantum computing capacities to the personal edge devices, the optimum approach is to have simple non-error corrected personal devices that offload the computational tasks to scalable quantum computers via edge servers with cryogenic components and fault-tolerant schemes. Hence the network elements deploy different encoding protocols. This article proposes quantum terminals that are compatible with different encoding protocols; paving the way for realizing mobile edge-quantum computing. By accommodating the atomic lattice processor inside a cavity, the entangling mechanism is provided by the Rydberg-Fermi cavity-QED technology. The gate operates by the Fermi scattering of a Rydberg electron from the plaquette atoms hosting the physical qubits. Therefore, different arrangements of logical-qubits derive the central atom over distinguished eigenstates, featuring photon emission at the early or late times distinguished by quantum interference. Applying an entanglement-swapping gate on two emitted photons would make the far-separated qubits entangled regardless of their encoding protocols. This gate provides a universal photonic interface for clustering the processors and connecting them with the quantum memories and quantum cloud that is compatible with different encoding formats.
