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…

Generalized Bicycle Codes with Low Connectivity: Minimum Distance Bounds and Hook Errors
Reza Dastbasteh, Olatz Sanz Larrarte, Arun John Moncy +3
We present new upper and lower bounds on the minimum distance of certain generalized bicycle (GB) codes beyond the reach of techniques for classical codes capable of even capturing…

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…
