Sample-Optimal Quantum Estimators for Pure-State Trace Distance and Fidelity via Samplizer

Qisheng Wang, Zhicheng Zhang

We settle the problem of estimating the trace distance and (square root) fidelity between -qubit pure quantum states to within additive error , given their independ…

Adaptive time Compressed QITE (ACQ) and its geometrical interpretation

Alberto Acevedo Meléndez, Carmen G. Almudéver, Miguel Angel Garcia-March +8

Imaginary time evolution (ITE) is a well-established method for ground-state preparation, a fundamental problem in many fields such as materials science, chemistry, and optimizatio…

A robust approach for time-bin encoded photonic quantum information protocols

Simon J. U. White, Emanuele Polino, Farzad Ghafari +6

Quantum states encoded in the time-bin degree of freedom of photons represent a fundamental resource for quantum information protocols. Traditional methods for generating and measu…

Strict Hierarchy for Quantum Channel Certification to Unitary

Kean Chen, Qisheng Wang, Zhicheng Zhang

We consider the problem of quantum channel certification to unitary, where one is given access to an unknown -dimensional channel , and wants to test whether $\math…

Counterfactual quantum measurements

Ingita Banerjee, Kiarn T. Laverick, Howard M. Wiseman

Counterfactual reasoning plays a crucial role in exploring hypothetical scenarios, by comparing some consequent under conditions identical except as results from a differing antece…
