Operational Metric for Quantum Chaos and the Corresponding Spatiotemporal-Entanglement Structure

N Dowling, K Modi - PRX Quantum, 2024 - APS
Chaotic systems are highly sensitive to a small perturbation and are ubiquitous throughout
the biological sciences, the physical sciences, and even the social sciences. Taking this as …

Unifying non-Markovian characterisation with an efficient and self-consistent framework

GAL White, P Jurcevic, CD Hill, K Modi - arxiv preprint arxiv:2312.08454, 2023 - arxiv.org
Noise on quantum devices is much more complex than it is commonly given credit. Far from
usual models of decoherence, nearly all quantum devices are plagued both by a continuum …

Conditional entropy and information of quantum processes

S Das, K Goswami, V Pandey - arxiv preprint arxiv:2410.01740, 2024 - arxiv.org
What would be a reasonable definition of the conditional entropy of bipartite quantum
processes, and what novel insight would it provide? We develop this notion using four …
