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…
Topologically noise robust network steering without inputs
Dhruv Baheti, Shubhayan Sarkar
Quantum networks with independent sources allow observing quantum nonlocality or steering with just a single measurement per node of the network, or without any inputs. Inspired by…
Detecting entanglement in any measurement using quantum networks
Shubhayan Sarkar
Entanglement is a key resource to demonstrate quantum advantage over classical strategies. Entanglement in quantum states is one of the most well-explored areas in quantum physics.…
Using quantum nonlocality for device-independent confirmation of relativistic effects
Shubhayan Sarkar
Synchronizing clocks to measure time is a fundamental process underpinning every practical communication task from GPS to parallel computation. However, as the current protocols ar…
