MUMBAI, India, July 30 -- Intellectual Property India has published a patent application (202641088391 A) filed by Vellore Institute Of Technology on July 20, 2026, for Cryogenic Coherence-Aware Quantum Circuit Restructuring Apparatus For Superconducting Qubit Processors.
Inventors include Santhi Krishnan; and Divy Kumar Agarwal.
The application for the patent was published on July 24, 2026, under issue no. 30/2026.
Abstract: The present invention discloses a cryogenic coherence-aware quantum circuit restructuring apparatus for suppressing decoherence-induced failures in superconducting quantum processors. The apparatus comprises a Transmon Qubit Array (200), Coherence Monitoring Unit (300), Coherence Topology Map generator (301), Hardware- Gated Circuit Buffer (302), FPGA-based Gate Reorder Scheduler (502), Commutativity Engine (501), and Dynamical Decoupling Pulse Injection Module (500). The apparatus continuously acquires per-qubit T1 and T2 coherence telemetry through microwave readout electronics and dynamically restructures quantum circuits based on real-time coherence conditions. The system performs adaptive qubit remapping, gate sequence reordering, and coherence-preserving pulse injection within a cryogenic control stack. By integrating physical qubit-state feedback with hardware-level circuit scheduling, the invention enables decoherence-aware quantum execution, improves circuit fidelity, and reduces computational failures in superconducting quantum processors operating at cryogenic temperatures.
