Efficient algorithms for quantum information bottleneck

Blog Article

The ability to extract relevant information is critical to learning.An ingenious approach as such is the information bottleneck, an invertatop squeeze bottle optimisation problem whose solution corresponds to a faithful and memory-efficient representation of relevant information from a large system.The advent of the age of quantum computing calls for efficient methods that work on information regarding quantum systems.Here we address this by proposing a new and general algorithm for the quantum generalisation of information bottleneck.Our algorithm excels in the speed and the definiteness of convergence compared with prior results.

It also works for a much broader range of problems, including the quantum extension of deterministic information bottleneck, an important variant of the original information bottleneck problem.Notably, we discover that a quantum system can achieve strictly silver lining herbs kidney support better performance than a classical system of the same size regarding quantum information bottleneck, providing new vision on justifying the advantage of quantum machine learning.
