Briefings

An IBM patent application proposes a scheduler to optimize quantum job sharing by grouping compatible circuits and reusing stored noise models to reduce error mitigation work. Filed May 5, 2025 and approved Nov 5, 2026, the system aims to increase hardware utilization by minimizing redundant measurements. The filing identifies key inventors including Ana Paula Appel, Daniel Josef Egger, and Sanjay Kumar Lalta Prasad Vishwakarma, though it does not report measured improvements in throughput, costs, or waiting times.

Key points

• The proposed system groups compatible quantum circuits to reuse stored noise models, reducing the need for repeated error mitigation measurements.
• The filing lists five inventors including Ana Paula Appel, Daniel Josef Egger, Sanjay Kumar Lalta Prasad Vishwakarma, and Razvan Paul Sebastian Brandhofer.

Context

IBM is seeking patent protection for a method that would let multiple users share a quantum processor while reducing some of the work needed to compensate for errors, potentially allowing providers to get more useful computation from their hardware.

Limitations

The evidence is limited to the patent application text; no experimental results, user feedback, or operational data are provided. The filing does not report measured improvements in throughput, waiting times, or costs, and the specific 127-qubit processor configuration is illustrative rather than a general specification.
