Towards Lattice Surgery Compilation for the Color Code Using Pipe Diagrams
Laura S. Herzog, Gilad Kishony, Robert Wille +1
Pipe diagrams have emerged as a powerful framework for flexible lattice surgery compilation and spacetime optimization for the surface code. In contrast, analogous compilation tech…
Color code off-the-hook: avoiding hook errors with a single auxiliary per plaquette
Gilad Kishony, Austin Fowler
Syndrome extraction in the planar color code is complicated by high weight stabilizers and hook errors that can reduce the circuit-level distance. With a single auxiliary qubit per…
Surface code off-the-hook: diagonal syndrome-extraction scheduling
Gilad Kishony, Austin Fowler
In the rotated surface code, hook errors (errors on auxiliary qubits midway through syndrome extraction that propagate to correlated two-qubit data errors) can reduce the circuit-l…
An iterative transversal CNOT decoder
Kwok Ho Wan, Mark Webber, Austin G. Fowler +1
Modern platforms for potential qubit candidates, such as trapped ions or neutral atoms, allow long range connectivity between distant physical qubits through shuttling. This opens…
