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…
Moving Analogue Horizons in Stationary Ferroelectrics
David Galvez-Poblete, Rubén M. Otxoa, Alvaro S. Nunez +1
We show that a traveling modulation of the polarization-gradient stiffness in a ferroelectric material induces an effective flow in its collective polarization dynamics. Within a c…
A spin-bond theory unifying non-relativistic spin splitting and emergent spin-orbit textures
S. Allende, R. M. Otxoa
Magnetic order with vanishing net magnetization can produce non-relativistic spin-split bands, broadly categorized into even-parity altermagnets and odd-parity \(p\)-wave magnets.…
Spin-orbit torque-driven synthetic antiferromagnetic oscillator
P. K. Rout, J. Godinho, F. Vilsmeier +9
Antiferromagnets offer a promising route toward robust spintronic devices because of their compensated magnetic order and exchange-enhanced spin dynamics. Here, we demonstrate a sp…
Universal theory of domain-wall width in multi-sublattice Heisenberg magnets
José M. LendÃnez, Marta Yanguas, Theodor Griepe +4
We propose a universal expression for the domain-wall width in generic multi-sublattice Heisenberg magnets, applicable to ferro-, antiferro-, and ferrimagnetic orders. The result f…
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…
