•Researchers at KRISS have identified that coherent photons, interacting via a resonator, directly cause dephasing in superconducting qubits.
•The dephasing profile was found to closely mirror the resonator's spectral characteristics, highlighting a precise relationship between these quantum components.
•Dynamical decoupling demonstrated robust capabilities in mitigating this coherence decay, offering a vital tool for quantum error control strategies.
•Xanadu Quantum Technologies has established a new industry benchmark for edge-coupling loss in photonic chips, critical for practical quantum computers.
•This achievement signifies a major step towards reducing optical signal degradation, enabling more efficient and scalable photonic quantum computing architectures.
•Lower loss in photonic packaging is essential for improving qubit fidelity and overall system performance in quantum hardware development.
