“…We further apply our method to a general noise model and obtain universal bounds applicable for any noise given in a certain form. Our work provides a useful systematic way of evaluating ultimate resource cost for error mitigation crucial for running useful algorithms, as well as presents another application of resource theories as useful theoretical tools to address concrete problems [17,[28][29][30][31][32].…”

We provide a general methodology for evaluating the optimal resource cost for an error mitigation employing methods developed in resource theories. We consider the probabilistic error cancellation as an error mitigation technique and show that the optimal sampling cost realizable using the full expressibility of near-term devices is related to a resource quantifier equipped with a framework in which noisy implementable operations are considered as the free resource, allowing us to obtain its universal bounds. As applications, we show that the cost for mitigating the depolarizing noise presented in [Temme, Bravyi, and Gambetta, Phys. Rev. Lett. 119, 180509 (2017)] is optimal, and extend the analysis to several other classes of noise model, as well as provide generic bounds applicable to general noise channels given in a certain form. Our results not only provide insights into the potential and limitations on feasible error mitigation on near-term devices but also display an application of resource theories as a useful theoretical toolkit.

“…When reactions are driven through photoexcitation and large energies must be dissipated in complex environments, nonequilibrium and nonadiabatic effects must be described on the same footing. Advances in the molecular theory of open quantum systems can provide guidance − for what quantities encode molecular dynamics most transparently. Further, far from equilibrium conditions occur ubiquitously in confined systems where driving forces and relaxation times can be large.…”

The properties of bulk water and aqueous solutions are known to change in the vicinity of an interface and/or in a confined environment, including the thermodynamics of ion selectivity at interfaces, transition states and pathways of chemical reactions, and nucleation events and phase growth. Here we describe joint progress in identifying unifying concepts about how air, liquid, and solid interfaces can alter molecular properties and chemical reactivity compared to bulk water and multicomponent solutions. We also discuss progress made in interfacial chemistry through advancements in new theory, molecular simulation, and experiments.

“…Lastly, measures capturing nuclear and electronic subsystems 28,29 with clear links to compass operation should be developed to assist in the interpretation of experiments 60 , such as those utilising quantum control 61 , alongside protocols for their implementation 62 . Other resources [63][64][65][66] such as entanglement 67 may also/still be of interest for systems. However, it has been shown that entanglement is unlikely to be of direct relevance to avian magnetoreception 22,30 .…”
