Enhancing quantum models of stochastic processes with error mitigation
Matthew Ho, Ryuji Takagi, Mile Gu
Error mitigation has been one of the recently sought after methods to reduce the effects of noise when computation is performed on a noisy near-term quantum computer. Interest in s…
Operational applications of the diamond norm and related measures in quantifying the non-physicality of quantum maps
Bartosz Regula, Ryuji Takagi, Mile Gu
Although quantum channels underlie the dynamics of quantum states, maps which are not physical channels -- that is, not completely positive -- can often be encountered in settings…
One-Shot Manipulation of Dynamical Quantum Resources
Bartosz Regula, Ryuji Takagi
We develop a unified framework to characterize one-shot transformations of dynamical quantum resources in terms of resource quantifiers, establishing universal conditions for exact…
Fundamental limitations on distillation of quantum channel resources
Bartosz Regula, Ryuji Takagi
Quantum channels underlie the dynamics of quantum systems, but in many practical settings it is the channels themselves that require processing. We establish universal limitations…
Framework for resource quantification in infinite-dimensional general probabilistic theories
Ludovico Lami, Bartosz Regula, Ryuji Takagi +1
Resource theories provide a general framework for the characterization of properties of physical systems in quantum mechanics and beyond. Here, we introduce methods for the quantif…
Operational quantification of continuous-variable quantum resources
Bartosz Regula, Ludovico Lami, Giovanni Ferrari +1
The diverse range of resources which underlie the utility of quantum states in practical tasks motivates the development of universally applicable methods to measure and compare re…
