Fault-tolerant execution of error-corrected quantum algorithms
Michael A. Perlin, Zichang He, Anthony Alexiades Armenakas +9
Scaling up quantum algorithms to tackle high-impact problems in science and industry requires quantum error correction and fault tolerance. While progress has been made in experime…
Helios: A 98-qubit trapped-ion quantum computer
Anthony Ransford, M. S. Allman, Jake Arkinstall +183
We report on Quantinuum Helios, a 98-qubit trapped-ion quantum processor based on the quantum charge-coupled device (QCCD) architecture. Helios features Ba hyperfine…
Quantum Error-Corrected Computation of Molecular Energies
Kentaro Yamamoto, Yuta Kikuchi, David Amaro +18
We present the first demonstration of an end-to-end pipeline with quantum error correction (QEC) for a quantum computation of the electronic structure of molecular systems. We calc…
Demonstration of logical qubits and repeated error correction with better-than-physical error rates
A. Paetznick, M. P. da Silva, C. Ryan-Anderson +29
The promise of quantum computers hinges on the ability to scale to large system sizes, e.g., to run quantum computations consisting of more than 100 million operations fault-tolera…
