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…
Hardware-Tailored Resource Estimation for Magic-State Distillation on Silicon Spin Qubits
Songqinghao Yang, Christopher K. Long, Rubén M. Otxoa +3
We present a resource analysis for generating high-fidelity logical magic states on silicon spin-qubit platforms. We consider a range of architectures, including a shuttling-based…
Surface-Code Thresholds and Qubit Footprints in Shuttling-Based Spin-Qubit Railways
Arun John Moncy, Reza Dastbasteh, Josu Etxezarreta Martinez +5
We present a fault-tolerant mapping of rotated surface codes onto a silicon spin-qubit railway architecture, utilizing electron shuttling to resolve the wiring fan-out…
Impact of leakage on the dynamics of a ST qubit implemented in a Double Quantum Dot device
Javier Oliva del Moral, Olatz Sanz Larrarte, Reza Dastbasteh +2
Spin qubits in quantum dots are a promising technology for quantum computing due to their fast response time and long coherence times. An electromagnetic pulse is applied to the sy…
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…
