One-shot entanglement generation and distillation via Petz recovery and binary hypothesis testing
Matthew Can, Mark M. Wilde
How much entanglement can two distant laboratories share when their connection is noisy? We relate this question to deciding which of two quantum hypotheses is present. Our one-sho…
Quantum simultaneous decoding via pretty-good measurements of tilted states
Mark M. Wilde
A multiple-access channel transmits messages from several senders to one receiver. For quantum outputs, the receiver must distinguish states depending on all messages, while tests…
Efficiently computable bounds on the energy-constrained quantum reading capacity
Vishal Singh, Zixin Huang, Mark M. Wilde
In quantum reading, classical messages are encoded in sequences of quantum channels and recovered by probing the channels and processing their outputs. We study the reading capacit…
Conditional contraction coefficients and their applications to quantum networks
Christoph Hirche, Ian George, Theshani Nuradha +1
Contraction coefficients quantify the loss of distinguishability induced by a channel and provide a strong form of the data-processing inequality. While standard contraction coeffi…
Limiting one-way distillable secret key via privacy testing of extendible states
Vishal Singh, Karol Horodecki, Aby Philip +1
The notions of privacy tests and -extendible states have both been instrumental in quantum information theory, particularly in understanding the limits of secure communication.…
Query complexities of quantum channel discrimination and estimation: A unified approach
Zixin Huang, Johannes Jakob Meyer, Theshani Nuradha +1
The goal of quantum channel discrimination and estimation is to determine the identity of an unknown channel from a discrete or continuous set, respectively. The query complexity o…
Query Complexity of Classical and Quantum Channel Discrimination
Theshani Nuradha, Mark M. Wilde
Quantum channel discrimination has been studied from an information-theoretic perspective, wherein one is interested in the optimal decay rate of error probabilities as a function…
Quantum Doeblin Coefficients: Interpretations and Applications
Ian George, Christoph Hirche, Theshani Nuradha +1
In classical information theory, the Doeblin coefficient of a classical channel provides an efficiently computable upper bound on the total-variation contraction coefficient of the…
Measured Hockey-Stick Divergence and its Applications to Quantum Pufferfish Privacy
Theshani Nuradha, Vishal Singh, Mark M. Wilde
The hockey-stick divergence is a fundamental quantity characterizing several statistical privacy frameworks that ensure privacy for classical and quantum data. In such quantum priv…
Extendible quantum measurements and limitations on classical communication
Vishal Singh, Theshani Nuradha, Mark M. Wilde
Unextendibility of quantum states and channels is inextricably linked to the no-cloning theorem of quantum mechanics, it has played an important role in understanding and quantifyi…
Device-Independent Certification of Multipartite Distillable Entanglement
Aby Philip, Mark M. Wilde
Quantum networks consist of various quantum technologies, spread across vast distances, and involve various users at the same time. Certifying the functioning and efficiency of the…
Unextendible entanglement of quantum channels
Vishal Singh, Mark M. Wilde
Quantum communication relies on the existence of high quality quantum channels to exchange information. In practice, however, all communication links are affected by noise from the…
No-go theorem for heralded exact one-way key distillation
Vishal Singh, Mark M. Wilde
The heralded exact one-way distillable secret key is equal to the largest expected rate at which perfect secret key bits can be probabilistically distilled from a bipartite state b…
