QuBE/Qubex: an integrated hardware-software system for superconducting qubit experiments with broadband control
Akinori Machino, Kazuhisa Ogawa, Takefumi Miyoshi +21
Achieving high-fidelity operation in large-scale superconducting qubit systems requires not only control hardware with broad frequency coverage, low crosstalk, and tight synchroniz…
Quantum Magic in early FTQC: From Diagonal Clifford Hierarchy No-Go Theorems to Architecture Design Blueprints
Hsueh-Hao Lu, Yasunari Suzuki, Yasunobu Nakamura +1
We address the circuit-design problem of maximizing quantum magic in early fault-tolerant quantum computing (early FTQC), where logical dynamics natively take the form of alternati…
Network-Based Quantum Computing: an efficient design framework for many-small-node distributed fault-tolerant quantum computing
Soshun Naito, Yasunari Suzuki, Yuuki Tokunaga
In fault-tolerant quantum computing, a large number of physical qubits are required to construct a single logical qubit, and a single quantum node may be able to hold only a small…
Accelerating BP-based decoders for QLDPC Codes with Local Syndrome-Based Preprocessing
Wenxuan Fan, Yasunari Suzuki, Gokul Subramanian Ravi +4
Due to the high error rate of qubits, detecting and correcting errors is essential for achieving fault-tolerant quantum computing (FTQC). Quantum low-density parity-check (QLDPC) c…

Entanglement among a large number of qubits is a crucial resource for many quantum algorithms. Such many-body states have been efficiently generated by entangling a chain of itiner…
Error Crafting in Mixed Quantum Gate Synthesis
Nobuyuki Yoshioka, Seiseki Akibue, Hayata Morisaki +2
In fault-tolerant quantum computing, errors in unitary gate synthesis is comparable with noise inherent in the gates themselves. While mixed synthesis can suppress such coherent er…
