In 1984, Bennett and Brassard came up with the revolutionary idea of quantum key distribution that we now know as the BB84 protocol. Rigorous proofs of correctness and tolerable error…
In this work, we present a novel quantum algorithm for edge detection in digital grayscale images. The proposed algorithm relies on the quantum advantage obtained by performing a Quantum Walsh-Hadamard…
Quantum simulation with optical lattices provides a powerful platform for quantum computation. It enables the engineering and study of strongly correlated quantum phases that can serve as building blocks for…
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…
