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…
