DART-Q : A Deadline-Driven Framework for Real-Time QLDPC Decoding
Ameya S. Bhave, Navnil Choudhury, Kanad Basu
Real-time quantum error correction places the classical decoder inside the fault-tolerant control loop under strict timing and memory constraints. For quantum low-density parity-ch…
Loss Mechanisms in Cryogenic Microwave Epitaxial AlN Resonators
Hemant Gulupalli, Navnil Choudhury, Jiacheng Xie +6
Epitaxial aluminum nitride (AlN) thin-film bulk acoustic resonators (FBARs) enable low loss filtering for future 6G systems. They also provide a compact approach for qubit sensing…
EPAR: Electromagnetic Pathways to Architectural Reliability in Quantum Processors
Navnil Choudhury, Yizhuo Tan, Jiaqi Yu +2
