Efficiently Computable Strategies and Limits for Bosonic Channel Discrimination
Zixin Huang, Ludovico Lami, Vishal Singh +1
Discriminating between noisy quantum processes is a central primitive for quantum communication, metrology, and computing. While discrimination limits for finite-dimensional channe…
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.…
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…
Extendibility limits quantum-secured communication and key distillation
Vishal Singh, Mark M. Wilde
Secret-key distillation from quantum states and channels is a central task of interest in quantum information theory, as it facilitates private communication over a quantum network…
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…
Quantifying the performance of approximate teleportation and quantum error correction via symmetric two-PPT-extendibility
Tharon Holdsworth, Vishal Singh, Mark M. Wilde
The ideal realization of quantum teleportation relies on having access to a maximally entangled state; however, in practice, such an ideal state is typically not available and one…
