Retreiving Data From A Black Hole

Quantum information could be retrieved from a black hole, according to new calculations by a theoretical physicist in the US. Seth Lloyd of the Massachusetts Institute of Technology has found that only a tiny amount of information — just half a quantum bit, or “qubit” — is lost from the black hole regardless of how many bits are in the hole to begin with. The unexpected discovery means that a black hole could behave as a good quantum computer and be used to perform useful calculations — if only we knew how to program it.
