Space‐Efficient Logical Qubit Architecture with a Bus for Magic State Consumption
Advanced Quantum Technologies, Volume 9, Issue 4, April 2026.This paper proposes a logical qubit architecture, considering the consumption of magic states. By constructing the patch to the magic state using the repetition code and data qubits using the surface code, the proposed architecture minimizes the number of qubits, referred to as the space cost.
