IEEE Quantum Week
Sandia will be participating in a Photonic Quantum Computing workshop at the 2025 IEEE International Conference on Quantum Computing and Engineering (QCE25).

Photonic Quantum Computing (PQC) Workshop
Photonic quantum computing (PQC) is emerging as a transformative technology with the potential to revolutionize utility-scale quantum computing, particularly in addressing critical national security challenges. Recent advancements in photonic quantum architectures position PQC as a leading contender in the field. However, pivotal scientific questions remain, particularly regarding the optimal methods for encoding quantum information or qubits in photons. This workshop will delve into various encoding strategies, including polarization, spatial-mode, time-bin, and frequency encodings, explore strategies for fault tolerance and error correction, and discuss recent breakthroughs and challenges in quantum photonic devices. Participants will engage in discussions about the advantages of leveraging multiple photonic quantum degrees of freedom and explore the implications of these advancements for the future of quantum computing.
Objectives
The goal of this workshop is to bring together the quantum computing, quantum error correction, and quantum photonics communities to participate in a discussion of the unique challenges and opportunities of photonic quantum computing. Research challenges ranging from fault tolerant resource state generation to novel quantum photonic devices will be discussed and explored.
