Satoya Imai: An Invitation to Randomized Measurements

Tuesday 18 Feb 2025, 10:30 → 11:30 Europe/Stockholm

How can we extract meaningful information about quantum systems and characterize their properties when faced with limited quantum control? One effective way is to use Randomized Measurements, offering the analysis of quantum correlations and entanglement in an experimentally-friendly way. The goal of my talk is to encourage you, both theoreticians and experimentalists, to know and use randomized measurements as a useful tool in quantum information processing tasks. To this end, I will first give a brief introduction to quantum entanglement and explain the challenges associated with its detection. Next, I will introduce the basic concept of randomized measurements and show their usefulness in characterizing entanglement. Finally, I will describe the general framework for randomized measurements and discuss several open problems from fundamental and practical perspectives. This talk is based on our review [Phys. Rep. 1095, 1 (2024)].
