Black holes are believed to be the most efficient quantum computers naturally existing in our universe. Standard computers do not have the capabilities to quickly solve some of the problems and unanswered questions facing researchers, but black holes may be able to provide insight into how quantum computers work and facilitate their development.

In this talk, discover how a quantum computer makes use of the quantum states of subatomic particles to both store and process information and explore the longstanding question of what happens if you fall into a black hole, from a new quantum perspective.
