  The black hole information paradox has been hotly debated for the last few
decades without a full resolution. This makes it desirable to find analogues of
this paradox in simple and experimentally accessible systems, whose resolutions
may shed light on this longstanding and fundamental problem. Here, we review
and resolve the apparent "information paradox" in two different interfaces
separating Abelian and non-Abelian quantum Hall states. In both cases, the
information carried by the pseudospin degree of freedom of the Abelian anyons
get scrambled when they cross the interface and enter the non-Abelian quantum
Hall liquid. Nevertheless, it is found that the scrambling mechanism depends on
the nature of the interface. The corresponding analogues of different concepts
in black hole physics such as event horizon, black hole interior, Hawking
radiation, and Page curve will also be discussed.
