Entropy density benchmarking of near-term quantum circuits
Researchers have proposed using entropy density accumulation as a benchmark for tracking how noise affects quantum processing unit performance. The work is presented as a proof-of-principle for monitoring near-term quantum circuits.

If the proof-of-principle holds on current multi-qubit devices, entropy density could be adopted as a complementary noise metric in cloud QPU benchmarking dashboards within two years.
Entropy density accumulation may require only standard circuit measurements rather than full tomography, making it cheaper to track as qubit counts grow. Adoption would depend on open-source implementations and validation across hardware from major QPU vendors, but the path from a published benchmark to integration into existing toolchains is visible.
