Self-testing quantum states via nonmaximal violation in Hardy's test of nonlocality
Ashutosh Rai, Matej Pivoluska, Souradeep Sasmal +3
Self-testing protocols enable certification of quantum devices without demanding full knowledge about their inner workings. A typical approach in designing such protocols is based…
Improvement in quantum communication using quantum switch
Arindam Mitra, Himanshu Badhani, Sibasish Ghosh
Applications of the quantum switch on quantum channels have recently become a topic of intense discussion. In the present work, we show that some useless (for communication) channe…
Extraction of Product and Higher Moment Weak Values: Applications in Quantum State Reconstruction and Entanglement Detection
Sahil, Sohail, Subhrajit Modak +2
Weak measurements introduced by Aharonov, Albert and Vaidman (AAV) can provide informations about the system with minimal back action. Weak values of product observables (commuting…
Robust entanglement detection in arbitrary two-mode Gaussian state: a Stokes-like operator-based approach
Arijit Dutta, Sibasish Ghosh, Jaewan Kim +1
Detection of entanglement in quantum states is one of the most important problems in quantum information processing. However, it is one of the most challenging tasks to find a univ…
Device-independent bounds from Cabello's nonlocality argument
Ashutosh Rai, Matej Pivoluska, Martin Plesch +3
Hardy-type arguments manifest Bell nonlocality in one of the simplest possible ways. Except for demonstrating nonclassical signature of entangled states in question, they can also…
Projective measurements under qubit quantum channels
Javid Naikoo, Subhashish Banerjee, A. K. Pan +1
The action of qubit channels on projective measurements on a qubit state is used to establish an equivalence between channels and properties of generalized measurements characteriz…
