Optimal Purity Estimation with Incoherent Measurements

Junseo Lee, Chirag Wadhwa

In this work, we consider the fundamental task of estimating the purity of an unknown state to within error . When one can perform general co…

Distributed Quantum Property Testing with Quantum Carrier Pigeons

Kenny Chen, Mina Doosti, Ryan Sweke +1

We introduce a framework for distributed quantum inference under communication constraints. In our model, distributed nodes each receive one copy of an unknown -dimensional…

Spectrum Estimation is Almost as Hard as Tomography

Marco Fanizza, Ryan O'Donnell, Chirag Wadhwa

We study the sample complexity of estimating and testing fundamental unitarily invariant properties of unknown quantum states; namely, the tasks of spectrum estimation, von Neumann…

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 …

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…

Noise-tolerant learnability of shallow quantum circuits from statistics and the cost of quantum pseudorandomness

Chirag Wadhwa, Mina Doosti

In this work, we study the learnability of quantum circuits in the near term. We demonstrate the natural robustness of quantum statistical queries for learning quantum processes, m…

Quantum Lock: A Provable Quantum Communication Advantage

Kaushik Chakraborty, Mina Doosti, Yao Ma +3

Physical unclonable functions(PUFs) provide a unique fingerprint to a physical entity by exploiting the inherent physical randomness. Gao et al. discussed the vulnerability of most…
