Breakthroughs in Photonic Quantum Computing: Paving the Way for Fault-Tolerant Quantum Computers

Recent years have witnessed significant advancements in building fault-tolerant quantum computers using photons. Researchers have employed various techniques, such as generating Schrödinger cat states and grid states through superpositions of photon number states, and combining them with quantum error correction codes like Gottesman-Kitaev-Preskill (GKP) codes. This has led to the creation of more robust photonic qubits, laying a solid foundation for building scalable fault-tolerant quantum computers. These groundbreaking results, published in top journals such as Science and Nature, mark a new milestone for photonic quantum computing technology.
