Abstract: Entanglement plays a crucial role in questions pertaining to the emergence and dynamics of bulk spacetime. The proposal of Ryu and Takayanagi, which relates the entanglement entropy of a boundary region to the area of a codimension-two bulk surface, has been crucial to this effort. However, holographic entanglement can also be formulated using `bit threads', i.e., divergenceless, norm-bounded vector fields. In this talk, I will review recent work that studies how Einstein’s equations are encoded in bit threads and how to understand bulk metric reconstruction in this language. Time permitting, I'll also comment on the Lorentzian analog of this problem, which is formulated in the context of the "complexity=volume" proposal. This talk will be based on 2007.07907, 2105.08063, 2105.12735 and work in progress.
