Quantum Sensors and Metrology

Definition

Tensor network states are mathematical constructs used to represent quantum states efficiently, particularly in many-body quantum systems. These states utilize a network of interconnected tensors, which encode information about the relationships between different quantum subsystems, allowing for scalable and effective representation of complex quantum states. This approach connects to various applications, including signal processing and data analysis for quantum sensors, where understanding and manipulating quantum information is crucial.
