Black hole-inspired quantum teleportation works without quantum magic
Physicists Sudhanva Joshi and Sunil Kumar Mishra at the Indian Institute of Technology (Banaras Hindu University) studied a quantum teleportation method inspired by black holes.
The idea comes from a theory in which information scrambled by one black hole could, under the right conditions, emerge from another through a wormhole.
Their simulation-based protocol achieved high fidelity without quantum magic, a special resource that can help quantum computers perform some calculations beyond efficient simulation by ordinary computers.
Quantum teleportation transfers a particle’s quantum state to another particle using entanglement and classical communication; it does not move matter or send information faster than light.
The result suggests this kind of teleportation does not need quantum magic to work remarkably well.
The study used quantum circuits to mimic information scrambling, rather than actual black holes, and the researchers’ findings do not mean that information has been teleported through a real wormhole.
Physicists found that a black hole-inspired quantum teleportation protocol can achieve high fidelity without quantum magic.
Sudhanva Joshi and Sunil Kumar Mishra of the Indian Institute of Technology (Banaras Hindu University) investigated how much computational power the protocol needs.
Their work used mathematical analysis of quantum circuits that mimic information scrambling in black holes.
Quantum teleportation transfers a particle’s quantum state to another particle using entanglement and classical communication.
The protocol is inspired by a theoretical idea in which information scrambled by one black hole could emerge from another connected by a wormhole.

What people are saying
Quantum teleportation doesn't work quite like the teleportation of science fiction.
The process doesn't allow information to travel faster than light, and the original quantum state is destroyed in the process.
How much quantum computational power does that scrambling really need?
