Optimal Quantum State Testing Even with Limited Entanglement
Chirag Wadhwa, Sitan Chen
In this work, we consider the fundamental task of quantum state certification: given copies of an unknown quantum state , test whether it matches some target state or is …
Distributed Quantum Property Testing with Communication Constraints
Mina Doosti, Ryan Sweke, Chirag Wadhwa
We introduce a framework for distributed quantum inference under communication constraints. In our model, distributed nodes each receive one copy of an unknown -dimensional…
Instance-Optimal Quantum State Certification with Entangled Measurements
Ryan O'Donnell, Chirag Wadhwa
We consider the task of quantum state certification: given a description of a hypothesis state and multiple copies of an unknown state , a tester aims to determine whether t…
Agnostic Process Tomography
Chirag Wadhwa, Laura Lewis, Elham Kashefi +1
Characterizing a quantum system by learning its state or evolution is a fundamental problem in quantum physics and learning theory with a myriad of applications. Recently, as a new…
