  We construct a new toy model of the holographic principle, named as
holographic qubit threads model, which is an enlightening step towards the
issue of spacetime emergence ("it from qubit"). More specifically, we propose
for the first time that each bit thread in a locking bit thread configuration
is in a "qubit" state, i.e., the quantum superposition state of two orthogonal
states. Using this thread/state correspondence, we can construct the explicit
expressions for the SS states corresponding to a set of bulk extremal surfaces
in the surface/state correspondence, and nicely characterize their entanglement
structure. Then we use the locking bit thread configurations to construct the
holographic qubit threads model, and we show that it is closely related to the
holographic tensor networks, kinematic space, and the connectivity of
spacetime.
