IBM Hardware Preserves Quantum Kernel Geometry to 98.9%

A recent study published on Quantum Zeitgeist has demonstrated that a four-qubit quantum kernel can preserve geometry to an impressive 98.9% on IBM's ibm_fez hardware.

The research, conducted by Rostyslav Sipakov of Kyiv National University of Construction and Architecture, used indoor air quality sensors as a testbed for evaluating the performance of quantum kernels in real-world scenarios.

While dynamical decoupling alone was not found to improve geometry preservation, gate twirling demonstrated significant improvements across multiple diagnostic metrics.
