A type-I fusion gate, boosted with four single-photon ancillas and passive linear optics, reaches 3/4 success probability via a distillation protocol.
Logically encoded 24-photon FBQC resource states can be deterministically produced from 3 quantum emitters and 11 CNOT gates by using symmetries to reduce the search over photon emission orderings.
Authors propose a low-optical-depth fusion-based photonic quantum computing architecture using quantum-dot emitters, adaptive repeat-until-success fusions, and time-bin qubits, with resource estimates and error-threshold simulations for fault tolerance.
Blueprint for a cavity-QED photon-atom platform that generates large-scale cluster states via atomic reuse and achieves a simulated 2.6% photon-loss threshold on the RHG lattice for fault-tolerant Clifford operations.
Time-optimal control produces Fock and Schrödinger cat states in light-matter systems at unit fidelity with lower energetic cost and noise robustness than adiabatic methods.
