Fundamental limitations on the device-independent quantum conference key agreement
Karol Horodecki, Marek Winczewski, Siddhartha Das
We provide several general upper bounds on the rate of a key secure against a quantum adversary in the device-independent conference key agreement (DI-CKA) scenario. They include b…
Quantum speed limits for information and coherence
Brij Mohan, Siddhartha Das, Arun Kumar Pati
The quantum speed limit indicates the maximal evolution speed of the quantum system. In this work, we determine speed limits on the informational measures, namely the von Neumann e…
Extendibility limits the performance of quantum processors
Eneet Kaur, Siddhartha Das, Mark M. Wilde +1
Resource theories in quantum information science are helpful for the study and quantification of the performance of information-processing tasks that involve quantum systems. These…
Upper bounds on device-independent quantum key distribution rates in static and dynamic scenarios
Eneet Kaur, Karol Horodecki, Siddhartha Das
In this work, we develop upper bounds for key rates for device-independent quantum key distribution (DI-QKD) protocols and devices. We study the reduced cc-squashed entanglement an…
