Network steering with arbitrarily low detection efficiency of any entangled measurement
Shubhayan Sarkar
Quantum nonlocality and its asymmetric counterpart, quantum steering, are among the most intriguing manifestations of quantum mechanics. From a theoretical perspective, they are no…
Polytopic Quantum Resource Theories: Geometry and Structures
Moein Naseri, Chirag Srivastava, Chandan Datta +2
Quantum resource theories provide a unifying framework to quantify, compare, and manipulate quantum resources under well-defined operational constraints. Here, we consider any reso…
Predictive supremacy of informationally-restricted quantum perceptron
Shubhayan Sarkar
In the current world, the use of artificial intelligence is penetrating every aspect of human life. The basic element of any artificial intelligence is a digital neuron, called a p…
Entanglement is not sufficient for most practical entanglement-based QKD protocols
Shubhayan Sarkar, Tushita Prasad, Karol Horodecki
Quantum key distribution (QKD) is the most explored application of quantum information theory. A central problem in entanglement-based QKD (EB-QKD), is whether every entangled stat…
Classifying the simplest Bell inequalities beyond qubits and their applications towards self-testing
Palash Pandya, Shubhayan Sarkar, Remigiusz Augusiak
Bell inequalities reveal the fundamentally nonlocal character of quantum mechanics. In this regard, one of the interesting problems is to explore all possible Bell inequalities tha…
