  It is suggested that quantum entanglement emerges from the holographic
principle stating that all of the information of a region (bulk bits) can be
described by the bits on its boundary surface. There are redundancy and
information loss in the bulk bits that lead to the nonlocal correlation among
the bulk bits. Quantum field theory overestimates the independent degrees of
freedom in the bulk. The maximum entanglement in the universe increases as the
size of the cosmic horizon and this could be related with the arrow of time and
dark energy.
