Limits RegistryPUBLIC RECORD
Limits RegistryXanadu Quantum Technologies' Borealis photonic quantum computer used 216 squeezed-light modes to perform a Gaussian boson sampling task that the team calculated would take a classical supercomputer far longer to replicate, published in Nature in June 2022. Unlike superconducting or trapped-ion qubits, photonic systems can in principle operate at room temperature and be networked over optical fiber, though they solve a narrower, sampling-specific class of problems.

The number of squeezed-state optical modes used by Xanadu's Borealis photonic quantum processor in its published Gaussian boson sampling quantum-advantage experiment.
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.
