Photonic qubits, which utilize photons to represent quantum information, are emerging as a promising solution to the challenges faced by traditional quantum computing methods. Unlike superconducting qubits, photonic qubits are less susceptible to environmental disturbances, potentially leading to more stable and scalable quantum systems. Companies like Photonic Inc. are at the forefront of this innovation, demonstrating significant progress in integrating photonic qubits into quantum computing architectures. In May 2024, Photonic Inc. achieved a milestone by demonstrating entanglement between remote T centre spins using telecom photons, addressing one of the primary challenges in scaling quantum systems. photonic.com
Further advancements include the development of a manufacturable platform for photonic quantum computing. In April 2024, researchers introduced a chipset designed and fabricated on full-size silicon wafers, incorporating components like high-performance single-photon sources and superconducting single-photon detectors. This approach aims to bridge the gap between laboratory research and practical, large-scale quantum computing applications. arxiv.org
