Quantum error correction well below the color code threshold

Ali Lavasani, Adam P. Reed, Joan M. Dreiling +20

Quantum error correction enables scalable fault-tolerant quantum computation by suppressing logical errors exponentially with code distance once physical error rates fall below a c…

Experimental validation of a compact fault-tolerant architecture for trapped ions

Noah Berthusen, Ali Lavasani, Asmae Benhemou +11

Quantum error correction (QEC) is beginning to enable logical operations that outperform their unencoded physical counterparts, but useful fault-tolerant computation will require m…

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…

Demonstrating an unconditional separation between quantum and classical information resources

William Kretschmer, Sabee Grewal, Matthew DeCross +8

A longstanding goal in quantum information science is to demonstrate quantum computations that cannot be feasibly reproduced on a classical computer. Such demonstrations mark major…

Scalable Multispecies Ion Transport in a Grid-Based Surface-Electrode Trap

Robert D. Delaney, Lucas R. Sletten, Matthew J. Cich +13

Quantum processors based on linear arrays of trapped ions have achieved exceptional performance, but scaling to large qubit numbers requires realizing two-dimensional ion arrays as…
