Phase transitions in random circuit sampling.

Undesired coupling to the surrounding environment destroys long-range correlations in quantum processors and hinders coherent evolution in the nominally available computational space. This noise is an outstanding challenge when leveraging the computation power of near-term quantum processors. It has been shown that benchmarking random circuit sampling with cross-entropy benchmarking can provide an estimate of the effective size of the Hilbert space coherently available.

Ergonomic risk assessment with DesignCheck to evaluate assembly work in different phases of the vehicle development process.

Occupational hazards exist, if the design of the work situation is not in accordance with ergonomic design principles. At assembly lines ergonomics is applied to the design of work equipment and tasks and to work organisation. The ignoring of ergonomic principles in planning and design of assembly work leads to unfavourable working posture, action force and material handling.

Musculoskeletal disorders are a challenge for the occupational physician as they can occur in a work-related situation., They must, however, be separated from occupational diseases. At first glance, the change in a worker's capability can be taken to indicate lower efficiency.
