Hardware-aware approach for fault-tolerant quantum computation

Our article “Topological and subsystem codes on low-degree graphs with flag qubits” [1], published in Physical Review X, takes a bottom-up approach to quantum error correcting codes that are adapted to a heavy-hexagon lattice – a topology we implement in our latest 65-qubit Hummingbird (r2) chip, available to IBM Q Network users in the Manhattan-named system.
