Gravitational radiation from known astrophysical sources is conventionally treated classically. This treatment corresponds, implicitly, to the hypothesis that a particular class of quantum-mechanical states — the so-called coherent states —…
Noise presents a significant challenge to quantum computing hardware, limiting the complexity of problems that can be tackled beyond just a few qubits. Quantum error correction (QEC) offers a theoretical…
: 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…
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…
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…
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…
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…
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…
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…
