Entropy Bounds via Hypothesis Testing and Its Applications to Two-Way Key Distillation in Quantum Cryptography
Rutvij Bhavsar, Junguk Moon, Joonwoo Bae
Quantum key distribution (QKD) achieves information-theoretic security, without relying on computational assumptions, by distributing quantum states. To establish secret bits, two…
POVM generated quantum trajectories without stochastic differential equations
Rutvij Bhavsar, N. D. Hari Dass
In this paper we examine the issue of quantum trajectories generated by QND-POVM's on {\it single} copies of unknown states. After an introduction to various aspects of quantum mea…
Composable framework for device-independent state certification
Rutvij Bhavsar, Lewis Wooltorton, Joonwoo Bae
Certifying a quantum state in a device-independent (DI) manner, in which no trust is placed on the internal workings of any physical components, is a fundamental task bearing vario…
Improvements on Device Independent and Semi-Device Independent Protocols of Randomness Expansion
Rutvij Bhavsar
To generate genuine random numbers, random number generators based on quantum theory are essential. However, ensuring that the process used to produce randomness meets desired secu…
Machine Learning Modeling of Wigner Intracule Functionals for Two Electrons in One Dimension
Rutvij Vihang Bhavsar, Raghunathan Ramakrishnan
In principle, many-electron correlation energy can be precisely computed from a reduced Wigner distribution function () thanks to a universal functional transformation…
