Researchers have developed a new method to estimate quantum correlations without needing a full classical description of the quantum states involved. This approach, termed measured quantum umlaut information ($U^M$), utilizes a quantum generative adversarial framework to optimize reference states and measurements. The framework is designed to estimate $U^M$ from measurement statistics of unknown bipartite states and classical-quantum channels, and can also optimize input probabilities for channels. This estimation technique could be valuable for assessing the correlation preservation capabilities of quantum memories and understanding the impact of noise on quantum devices. AI
