Project mention: Show HN: Generate high-width, near-ideal transverse field Ising model samples | news.ycombinator.com | 2025-07-24
Transverse field Ising model (TFIM) is the physical system at the core of most claimed cases of algorithmic "quantum advantage" (notably excluding Shor's integer factoring algorithm). It's easy to compare these results to Qiskit Aer Trotterization: see https://github.com/unitaryfoundation/qrack/blob/main/scripts....
