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…
Trade-offs between Quantum and Classical Resources in the Linear Combination of Unitaries
Kaito Wada, Hiroyuki Harada, Yasunari Suzuki +3
The randomized linear combination of unitaries (LCU) method with many applications to early fault-tolerant quantum computing algorithms has been proposed. This quantum algorithm co…
Addressing requirements for crosstalk-free quantum-gate operation in many-body nanofiber cavity QED systems
Tim Keller, Seigo Kikura, Rui Asaoka +3
A distributed network architecture in which flying photons connect individual modules containing stationary atomic qubits is a promising approach for scaling up neutral-atom based…
Fault-tolerant logical state construction based on cavity-QED network
Rui Asaoka, Yasunari Suzuki, Yuuki Tokunaga
Exploring an efficient and scalable architecture of fault-tolerant quantum computing (FTQC) is vital for demonstrating useful quantum computing. Here, we propose and evaluate a sca…
Logical entanglement distribution between distant 2D array qubits
Yuya Maeda, Yasunari Suzuki, Toshiki Kobayashi +3
Sharing logical entangled pairs between distant quantum nodes is a key process to achieve fault tolerant quantum computation and communication. However, there is a gap between curr…
Data-Efficient Error Mitigation for Physical and Algorithmic Errors in a Hamiltonian Simulation
Shigeo Hakkaku, Yasunari Suzuki, Yuuki Tokunaga +1
Quantum dynamics simulation via Hamilton simulation algorithms is one of the most crucial applications in the quantum computing field. While this task has been relatively considere…
