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 …
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…
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…
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…
