Toward Large Nonradiating Qubits: When Quantum Engineering Meets Photonics
Advanced Quantum Technologies, Volume 9, Issue 3, March 2026.Nonradiating superconducting qubits suppress radiative losses through photonic‐inspired mechanisms such as anapole states and bound states in the continuum (BICs). This review surveys theoretical foundations and recent implementations of large, wavelength‐scale qubits that confine electromagnetic energy while maintaining coherence.
