Lattice-surgery scheduling is mapped to 3D path embedding and solved with look-ahead Dijkstra projection, yielding 3.8x lower execution time on quantum phase estimation benchmarks versus greedy scheduling.
Fusion failure sets a noise floor that blocks low-overhead subthreshold operation in all-linear-optics fusion-based quantum computers, but quantum-emitter-spin architectures lower this floor by orders of magnitude.
Quantum sieving for SVP in dimension 400 needs ~10^13 physical qubits and ~10^31 years under optimistic assumptions, offering no practical speedup over classical methods.
Synchronizable hybrid subsystem codes are built from classical cyclic codes C and D with C^perp subset C subset D via CSS construction to correct Pauli and synchronization errors, tolerate gauge errors, and carry both classical and quantum information, with explicit trade-offs.
A layered resource estimation framework applied to three quantum applications shows practical advantage requires 10^5-10^6 physical qubits, driven by size, speed, and controllability.
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.
