Parity-unfolded distillation architecture for noise-biased platforms
Konstantin Tiurev, Christoph Fleckenstein, Christophe Goeller +6
We introduce the parity-unfolded architecture, a fault-tolerant quantum computing scheme that relies on direct preparation and teleportation of small-angle rotations …
Leveraging biased noise for more efficient quantum error correction at the circuit-level with two-level qubits
Josu Etxezarreta Martinez, Paul Schnabl, Javier Oliva del Moral +3
Tailoring quantum error correction codes (QECC) to biased noise has demonstrated significant benefits. However, most of the prior research on this topic has focused on code capacit…
Optimal Decoder for the Error Correcting Parity Code
Konstantin Tiurev, Christophe Goeller, Leo Stenzel +4
We present a two-step decoder for the parity code and evaluate its performance in code-capacity and faulty-measurement settings. For noiseless measurements, we find that the decodi…
SpinHex: A low-crosstalk, spin-qubit architecture based on multi-electron couplers
Rubén M. Otxoa, Josu Etxezarreta Martinez, Paul Schnabl +3
Semiconductor spin qubits are an attractive quantum computing platform that offers long qubit coherence times and compatibility with existing semiconductor fabrication technology f…
