Automated Flag-based Fault-Tolerant State Preparation using Integer Linear Programming
Ben Criger, Aaron Hankin, Justin J. Burau +1
Post-selected stabilizer state preparation is a necessary subroutine in fault-tolerant quantum computation, both for initialization of logical qubits, and for logical-ancilla-based…
Flagging the Clifford hierarchy:~Fault-tolerant logical rotations via measuring circuit gauge operators of non-Cliffords
Shival Dasu, Ben Criger
We provide a recursively defined sequence of flag circuits which will detect logical errors induced by non-fault-tolerant gates on CSS codes with a…
Fast stabilizer state preparation via AI-optimized graph decimation
Michael Doherty, Matteo Puviani, Jasmine Brewer +4
We propose a general method for preparing stabilizer states with reduced two-qubit gate count and depth compared to the state of the art. The method starts from a graph state repre…
Computing with many encoded logical qubits beyond break-even
Shival Dasu, Matthew DeCross, Andrew Y. Guo +42
High-rate quantum error correcting (QEC) codes encode many logical qubits in a given number of physical qubits, making them promising candidates for quantum computation. Implementi…
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…
Characterization of syndrome-dependent logical noise in detector regions
Matthew Girling, Ben Criger, Cristina Cirstoiu
Characterizing how quantum error correction circuits behave under realistic hardware noise is essential for testing the premises that enable scalable fault tolerance. Logical error…
