论文摘要
我们证明，某些量子传送方案在Sachdev-ye-Kitaev模型中表现出测量诱导的相变。也就是说，如果我们以较大的投影率或以较大的耦合速率应用它们，则Kitaev-Yoshida和Gao-Jo-jo-jo-jo-jo-joshida和Gao-jo-jo-jo-jo-jo-joshiss wall壁方案具有相变。众所周知，以较小的速度，他们只能在小时的窗口内进行传送。我们表明，以很大的速度，该系统进入了一个新的稳定状态，可以随时进行传送。在双重jackiw-teitelboim重力中，这些相变为对永恒的蠕虫孔的形成。在Kitaev-Yoshida案中，这种新型的虫洞类型得到了连续预测的支持。
We demonstrate that some quantum teleportation protocols exhibit measurement induced phase transitions in Sachdev-Ye-Kitaev model. Namely, Kitaev-Yoshida and Gao-Jafferis-Wall protocols have a phase transition if we apply them at a large projection rate or at a large coupling rate respectively. It is well-known that at small rates they allow teleportation to happen only within a small time-window. We show that at large rates, the system goes into a new steady state, where the teleportation can be performed at any moment. In dual Jackiw-Teitelboim gravity these phase transitions correspond to the formation of an eternal traversable wormhole. In the Kitaev-Yoshida case this novel type of wormhole is supported by continuous projections.
