Generalized Quantum Assisted Simulator
Tobias Haug, Kishor Bharti
We provide a noisy intermediate-scale quantum framework for simulating the dynamics of open quantum systems, generalized time evolution, non-linear differential equations and Gibbs…
Quantum Assisted Simulator
Kishor Bharti, Tobias Haug
Quantum simulation can help us study poorly understood topics such as high-temperature superconductivity and drug design. However, existing quantum simulation algorithms for curren…
Optimal Probes for Global Quantum Thermometry
Wai-Keong Mok, Kishor Bharti, Leong-Chuan Kwek +1
Quantum thermodynamics has emerged as a separate sub-discipline, revising the concepts and laws of thermodynamics, at the quantum scale. In particular, there has been a disruptive…
Quantum Assisted Eigensolver
Kishor Bharti
We propose a hybrid quantum-classical algorithm for approximating the ground state and ground state energy of a Hamiltonian. Once the Ansatz has been decided, the quantum part of t…
Iterative Quantum Assisted Eigensolver
Kishor Bharti, Tobias Haug
The task of estimating the ground state of Hamiltonians is an important problem in physics with numerous applications ranging from solid-state physics to combinatorial optimization…
Graph-theoretic approach to dimension witnessing
Maharshi Ray, Naresh Goud Boddu, Kishor Bharti +2
A fundamental problem in quantum computation and quantum information is finding the minimum quantum dimension needed for a task. For tasks involving state preparation and measureme…
Robust Semi-Device Independent Certification of All Pure Bipartite Maximally Entangled States via Quantum Steering
Harshank Shrotriya, Kishor Bharti, Leong-Chuan Kwek
The idea of self-testing is to render guarantees concerning the inner workings of a device based on the measurement statistics. It is one of the most formidable quantum certificati…
Machine Learning meets Quantum Foundations: A Brief Survey
Kishor Bharti, Tobias Haug, Vlatko Vedral +1
The goal of machine learning is to facilitate a computer to execute a specific task without explicit instruction by an external party. Quantum foundations seeks to explain the conc…
