Quantum Codes with Arbitrary Z-Rotation logical Gates and Applications to Fault-Tolerant Code Switching

Reza Dastbasteh, Ruben M. Otxoa, Pedro M. Crespo +1

A technique for realizing a universal set of fault-tolerant quantum operations is the code switching method, which leverages two quantum codes with complementary sets of transversa…

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…
