Classical computers keep matching quantum advantage claims
Physicists periodically claim a quantum computer has solved a problem beyond any classical machine's reach, and other researchers keep testing those claims against improved classical methods like tensor networks. The arc tracks whether classical hardware keeps closing the gap or whether some future claim finally holds.
The story so far

Joseph Tindall and Miles Stoudenmire of the Simons Foundation's Flatiron Institute used tensor networks, a technique for compressing complex quantum wave functions, to reproduce on classical hardware, including a personal laptop, results a team had claimed required a quantum computer to model hundreds of entangled qubits, matching both the theoretical predictions and the quantum computer's own output.
