Logical Encoding Raised an Optical Bell Measurement's Success Rate Above 50 Percent

A four-photon experiment identified logical Bell states with 70.8 percent average success. The gain could help photonic networks and computers, but it was postselected and did not provide full error correction.

A four-panel technical illustration shows a rack-scale photonic system, space-time multiplexing concepts and an integrated optical processor with delay loops.

A Chip-Scale Boson Sampler Recorded 11,059 Clicks in One Millisecond

A lithium-niobate processor combines spatial and time-bin mixing at 4 gigahertz. Its scale is substantial, but its quantum-advantage and AI results remain author-reported benchmarks.
