| dc.description.abstract | Transport in a quantum point contact (QPC) can be used to generate many-body entanglement of Fermi
seas in the leads. A universal relation is found between the generated entanglement entropy and the
fluctuations of electric current, which is valid for any protocol of driving the QPC. This relation offers a
basis for direct electric measurement of entanglement entropy. In particular, by utilizing space-time
duality of 1D systems, we relate electric noise generated by opening and closing the QPC periodically in
time with the seminal S=1/3 logL prediction of conformal field theory. | en |
