Quantum Computing Just Beat the Best Classical Computer — Here Is the Engineering That Made It Happen
On May 6, 2026, Q-CTRL ran a materials science simulation on an IBM quantum computer in 2 minutes. The best classical supercomputer needed over 100 hours to reach the same accuracy — and then gave up. The day before, IBM's quantum computers simulated a 12,635-atom protein with Cleveland Clinic and RIKEN, 40 times larger than anything attempted six months prior. After 30 years of promises, quantum advantage arrived. Here is what actually changed.
