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…

Implementing Fault-tolerant Entangling Gates on the Five-qubit Code and the Color Code

C. Ryan-Anderson, N. C. Brown, M. S. Allman +34

We compare two different implementations of fault-tolerant entangling gates on logical qubits. In one instance, a twelve-qubit trapped-ion quantum computer is used to implement a n…

High-fidelity and Fault-tolerant Teleportation of a Logical Qubit using Transversal Gates and Lattice Surgery on a Trapped-ion Quantum Computer

C. Ryan-Anderson, N. C. Brown, C. H. Baldwin +21

Quantum state teleportation is commonly used in designs for large-scale fault-tolerant quantum computers. Using Quantinuum's H2 trapped-ion quantum processor, we implement the firs…

A Race Track Trapped-Ion Quantum Processor

S. A. Moses, C. H. Baldwin, M. S. Allman +93

We describe and benchmark a new quantum charge-coupled device (QCCD) trapped-ion quantum computer based on a linear trap with periodic boundary conditions, which resembles a race t…

Realization of real-time fault-tolerant quantum error correction

C. Ryan-Anderson, J. G. Bohnet, K. Lee +14

Correcting errors in real time is essential for reliable large-scale quantum computations. Realizing this high-level function requires a system capable of several low-level primiti…
