Measuring Entanglement Entropy of a Generic Many-Body System with a Quantum Switch
Measuring Entanglement Entropy of a Generic Many-Body System with a Quantum Switch
Entanglement entropy has become an important theoretical concept in condensed matter physics because it provides a unique tool for characterizing quantum mechanical many-body phases and new kinds of quantum order. However, the experimental measurement of entanglement entropy in a many-body system is widely believed to be unfeasible, owing to the …
