Limits RegistryPUBLIC RECORD
Limits RegistryChina's Micius satellite distributed entangled photon pairs to two ground stations 1,203 km apart (Delingha and Lijiang) in a landmark 2017 experiment published in Science, demonstrating satellite-based entanglement distribution far beyond the ~100 km limit of direct fiber-based entanglement distribution at the time. The result underpinned subsequent satellite-relayed intercontinental quantum key distribution demonstrations by the same team.
The question, scope, and sources behind this Registry record.
China's Micius satellite distributed entangled photon pairs to two ground stations 1,203 km apart (Delingha and Lijiang) in a landmark 2017 experiment published in Science, demonstrating satellite-based entanglement distribution far beyond the ~100 km limit of direct fiber-based entanglement distribution at the time. The result underpinned subsequent satellite-relayed intercontinental quantum key distribution demonstrations by the same team.
The greatest ground-station separation distance over which entangled photon pairs were distributed using China's Micius satellite, enabling loophole-free Bell tests and satellite-based quantum key distribution.
Change a parameter to stress-test whether a proposed result is still inside the published specification. This is an audit aid, not a proof checker.
This record has no editable parameters. Read the formal question and assumptions before challenging it.
Current frontiers derived from accepted Claims.
An observed or demonstrated result; no opposing bound is implied.
The frontier is not sacred
Most progress starts with a disagreement that survives contact with evidence. If you can push the known lower bound up or pull the upper bound down, show us the work.
≥ when you have shown that at least this value is achievable.≤ when you have shown that anything above this value is impossible.No vibes. State the value, define the scope, and link the paper, proof, code, or reproduction that lets another person check it. Editors review every challenge before the public record changes.
