On the Cover: On-chip path encoded photonic quantum Toffoli gate

The image on the cover for Photonics Research Volume 10, Issue 7, demonstrates an on-chip path encoded photonic quantum Toffoli gate enabled by the 3D capability of the femtosecond laser direct writing (FLDW) for the first time, whose truth-table fidelity is higher than 85.5%. The image is based on original research by Meng Li et al. presented in their paper "On-chip path encoded photonic quantum Toffoli gate", Photonics Research 10 (7), 1533 (2022).
