Discussion

Quantum simulations reveal effective domain wall qubits in spin chains, suggesting robustness for quantum information encoding.

Domain wall qubits show potential for encoding quantum information, as demonstrated by DMRG simulations.
The system exhibits a well-defined low-energy sector with opposite chiralities, relevant for qubit design.
Coupled quantum spin-1/2 chains allow effective single-qubit and two-qubit gates, improving quantum architecture.
Observing tunneling between DW states highlights their viability in real-time quantum information processing.

Qu et al. (2025) studied this question.
