Measurement and Teleportation in the cSYK/JT Correspondence (2501.05905v2)
Published 10 Jan 2025 in hep-th, cond-mat.stat-mech, and quant-ph
Abstract: We consider two complex SYK models entangled in a thermofield double (TFD) state and investigate the effect of one-sided projective measurements. As measurement operator we choose single site charge operators. Performing a measurement results in a non-zero $U(1)$ charge. The entropy curve differs from the previously studied SYK model due to a thermodynamic phase transition that takes place after a certain charge is reached. We also match our results to a dual bulk description. Finally, a teleportation protocol is provided to support the notion of a traversable wormhole being formed.
