Disentangling the black hole vacuum

We study the question of whether disentanglement of Hawking radiation can be achieved with any local operation. We assume that the operation we look for is unitary, from which follow restrictions on its action on basis vectors. This allows us to formulate requirements on the operation of disentanglement. We then show that these requirements can be fulfilled by a timelike boundary condition in the near-horizon area and that the local observer does not notice the presence of the boundary and does not encounter a firewall.
