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…

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…
