The Centre for Quantum Computer Performance and Integration aims to solve the scientific challenges that hinder the development of useful quantum computers. The Centre will synergistically develop high-performance quantum hardware, operate it in a resource-efficient way, and integrate diverse physical platforms across solid-state, optical and atom-based devices.

The final Optics CQC2T Workshop held on 17-20 November 2025 brought our community together once again, blending fresh scientific progress with a heartfelt sense of legacy, nostalgia, and appreciation for the many years of collaboration that brought us to this moment.

We provide a comprehensive overview of heralded entanglement generation with photons—covering theory, experiments, and its wide-ranging applications in quantum computation, communication, and metrology—while also pointing toward new frontiers for the field. A huge thanks to our co-authors from Bristol—this really was a team effort from start to finish.
