Reliable quantum certification of photonic state preparations

2015 · Nature Communications

Quantum technologies promise a variety of exciting applications. Even though impressive progress has been achieved recently, a major bottleneck currently is the lack of practical certification techniques. The challenge consists of ensuring that classically intractable …

Closed-form analytic expressions for shadow estimation with brickwork circuits

2022 · arXiv (Cornell University)

Properties of quantum systems can be estimated using classical shadows, which implement measurements based on random ensembles of unitaries. Originally derived for global Clifford unitaries and products of single-qubit Clifford gates, practical implementations are limited …
