: We first talk about indefiniteness of causal order and how it can be exploited in quantum information processing tasks. We then introduce the task of random-receiver quantum communication, in…
In this talk, I will try to elucidate the rapport of work and information in the context of a minimal quantum mechanical setup: A converter of heat input to work…
In this talk, I will be discussing two classes of Bell diagonal indecomposable entanglement witnesses in C^4 ⊗ C^4. The first class is a generalization of the well-known Choi witness…
Incompatibility of quantum devices is a useful resource in various quantum information theoretical tasks, and it is at the heart of some fundamental features of quantum theory. In the work…
Quantum dense coding (DC), first introduced by Bennett and Weisner for qubit systems, was generalized to the continuous variable (CV) paradigm by Braunstein and van Look for a single sender…
Non-Hermitian rotation-time reversal (RT)-symmetric spin models possess two distinct phases, the unbroken phase in which the entire spectrum is real and the broken phase which contains complex eigenspectral, thereby indicating…
In the classical RAM, we have the following useful property. If we have an algorithm that uses M memory cells throughout its execution, and in addition is sparse, in the…
Metamaterials are artificial materials consisting of micro or nano composites which exhibit properties different from their components in sub-wavelength regime. These materials are finding applications in several areas such as…
We give a comprehensive characterization of the computational power of shallow quantum circuits combined with classical computation. Specifically, for classes of search problems, we show that the following statements hold,…
From quantum computation to communication, design of quantum devices and peripheral technology relies strongly on the interaction of light with matter. This requires not only modelling these interactions at the…
