High-Performance and Scalable Fault-Tolerant Quantum Computation with Lattice Surgery on a 2.5D Architecture
Yosuke Ueno, Taku Saito, Teruo Tanimoto +4
Due to the high error rate of a qubit, detecting and correcting errors on it is essential for fault-tolerant quantum computing (FTQC). Among several FTQC techniques, lattice surger…
C3-VQA: Cryogenic Counter-based Co-processor for Variational Quantum Algorithms
Yosuke Ueno, Satoshi Imamura, Yuna Tomida +5
Cryogenic quantum computers play a leading role in demonstrating quantum advantage. Given the severe constraints on the cooling capacity in cryogenic environments, thermal design i…
SFQ counter-based precomputation for large-scale cryogenic VQE machines
Yosuke Ueno, Satoshi Imamura, Yuna Tomida +5
The variational quantum eigensolver (VQE) is a promising candidate that brings practical benefits from quantum computing. However, the required bandwidth in/out of a cryostat is a…
Inter-temperature Bandwidth Reduction in Cryogenic QAOA Machines
Yosuke Ueno, Yuna Tomida, Teruo Tanimoto +4
The bandwidth limit between cryogenic and room-temperature environments is a critical bottleneck in superconducting noisy intermediate-scale quantum computers. This paper presents…
