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.

A fundamental limit on the performance of geometrically-tuned planar resonators [PDF]

, 2011
Geometric frequency tuning in planar electromagnetic resonators is common in many applications. It comes, however, at a penalty in the resonance quality, Q0. The literature traces the causes of such penalty often in terms of the shortcomings in the added

Reconfigurable Metamirrors Based on Compliant Mechanisms

Advanced Functional Materials, Volume 36, Issue 10, 2 February 2026.
Providing the basis for numerous practical applications, the reconfigurability of metadevices is of great importance. Through the integration of controlled mechanical deformation with chiral meta‐atoms, a compliant mechanism based metamirror is demonstrated for active control over the polarization of electromagnetic waves.
