Emerging Trends in Photonic Quantum Computing

Quantum computing has the potential to revolutionize information processing by leveraging the principles of superposition, entanglement, and quantum interference. Photonic quantum computing, in particular, is emerging as a promising platform due to its intrinsic scalability, robustness to decoherence, and ability to operate at room temperature. Recent advances in integrated photonic circuits, quantum light sources, quantum memory, and quantum error correction are rapidly shaping the future of this field, bringing practical quantum computing closer to reality. This special issue aims to provide a comprehensive overview of cutting-edge research in photonic quantum computing, highlighting breakthroughs in device physics, architectures, and quantum algorithms. We invite contributions that explore novel experimental and theoretical advancements in this rapidly evolving domain.

Topics of interest include, but are not limited to:

• Integrated photonic platforms for quantum information processing
• Quantum photonic gates and circuits
