N2 - This paper introduces a new Distributed Quantum Error Correction (DQEC) architecture based on Calderbank-Steane-Shor (CSS) codes to address the limitations of physical qubit availability in monolithic systems. The original quantum state is first distributed across the Greenberger-Horne-Zeilinger (GHZ) state, generated on seven distinct Quantum Processing Units (QPUs), and then encoded as superpositions of even-weight and odd-weight components of the CSS code. By distributing the seven physical qubits needed for a logical qubit based on CSS, each QPU can accommodate more logical qubits compared to conventional (non-distributed) cases where all the physical qubits of a logical qubit are confined to a single QPU. The effectiveness of the proposed architecture is evaluated in terms of its ability to detect X-errors, Z-errors, and Y-errors through stabilizer generators.
