The Connes embedding conjecture (1976), via the equivalent Tsirelson problem.

Status is community- and machine-tracked and may lag. Verify independently before investing effort.

Assessment

Renown 4/5

A 44-year-old operator-algebra conjecture with connections across quantum information.

Attackability 0/5

No finite witness exists in any sense; refuted through complexity theory (MIP* = RE).
