A new paper shows how the possibility of
wormholes linking quantum - entangled black holes could be tested in the laboratory.
The idea is the same as that of
a wormhole linking two distant points in spacetime, hence the nickname.

In fact, Susskind contends, Alice and Bob could prove ER = EPR simply by jumping into two entangled black holes,
linked by a
wormhole.
Applying this to event horizons, they say that individual particles of Hawking radiation are
linked via
wormhole to the inside of the black hole.
One suggested way of achieving this involves the construction of tunnels called
wormholes that
link different parts of space at different times.
The quantum
link forces particles near the
wormhole's horizon into a particular quantum state, «freezing» them and giving away the horizon's location.
Since
wormholes are contortions of spacetime geometry — described by Einstein's gravitational equations — identifying them with quantum entanglement would forge a
link between gravity and quantum mechanics.
Wormholes may forge that
link.
If ER = EPR is right, a
wormhole will
link those black holes; entanglement, therefore, can be described using the geometry of
wormholes.
In high school, American students encounter a kind of
wormhole connecting geometry and algebra: Geometric objects like circles and ellipses are
linked to algebraic equations like y2 = x3 — x + 1.
