Quantum X Labs shares rise 8.5% on LayerQake validation with IBM processors

Shares of Quantum X Labs rose 8.5% to $4.21 after the company experimentally validated its LayerQake quantum calibration methodology on three IBM quantum processors. The approach reduced measurement bias from hardware-induced noise to below 6%, from roughly 11-15% previously, and demonstrated a 15- to 21-fold reduction in maximum cumulative error. The company believes the experiment shows substantial improvements in computational accuracy and reductions in cumulative errors caused by quantum hardware noise.
