SUMMARY:NIAQ: Adaptive Non-Ideality-Aware Qubit Readout for Long-Term Accu
 racy
DESCRIPTION:Yuyang Du (Nanyang Technological University); Yi Sheng Chong (
 Institute of Microelectronics, Agency for Science, Technology and Research
 ); Wang Ling Goh (Nanyang Technological University); Benjamin Lienhard (Te
 chnical University of Munich); and Anh Tuan Do (Institute of Microelectron
 ics, Agency for Science, Technology and Research)\n\nHigh-accuracy qubit-s
 tate readout is critical for quantum computation. While existing hardware-
 based qubit-state discriminators assume stable readout statistics across m
 easurement shots, realistic long-running tasks like chemistry simulation s
 uffer from slow noise fluctuations and drift that severely degrade fidelit
 y over time. We present NIAQ, an adaptive software–hardware co-design comb
 ining Kalman filtering for drift tracking with MLP discriminators for robu
 stness against noise, together with degradation rate (%/hour) as a novel m
 etric to quantify long-term stability. NIAQ achieves 88% qubit-state-reado
 ut accuracy in multi-qubit dataset that is equivalent to 1-day runtime, co
 mpared to the 61% baseline qubit-state discriminator, and yields 19× lower
  degradation rate. Optimized for low-power real-time operation on ASIC, po
 st-synthesis results in 28-nm CMOS show 148mW power and 5ns delay, achievi
 ng 7.7× power and 6.4× latency improvements compared to the state-of-the-a
 rt.\n\nTopics: Quantum\n\nTrack: DES6. Quantum Computing, Systems\n\nSessi
