  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.
