Short answer

Not a single study

No clear answer.

The article covers a research area rather than reporting a specific new paper, so there is no single study to check it against.

Checked against the study summary. The full text wasn't available, so some details couldn't be settled either way.

Claim by claim

What the story asserts. With no source study, there is nothing to check these against.

Claim 1 of 6Not checkedPhysicists Sudhanva Joshi and Sunil Kumar Mishra of the Indian Institute of Technology (Banaras Hindu University) reportedly found that a black hole-inspired teleportation protocol can achieve high fidelity without requiring quantum magic.View evidenceHide evidence

As statedhigh fidelity

Not checked

NewsLink could not identify one source study, so this claim was not compared against a paper.

Claim 2 of 6Not checkedThe story says the researchers mathematically compared two scrambling methods in the protocol: Clifford circuits, which do not require quantum magic, and Haar-random scramblers, which typically possess substantial quantum magic.View evidenceHide evidence

Not checked

NewsLink could not identify one source study, so this claim was not compared against a paper.

Claim 3 of 6Not checkedAccording to the article, both methods achieved the same average teleportation fidelity, but the Haar-random approach was much more consistent than the Clifford approach.View evidenceHide evidence

As statedaround 40,000 times greater variance in one eight-qubit comparison

Not checked

NewsLink could not identify one source study, so this claim was not compared against a paper.

Claim 4 of 6Not checkedThe article says that in larger modeled quantum systems, the Clifford approach became increasingly successful and its teleportation fidelity approached perfection even without quantum magic.View evidenceHide evidence

As statedapproaching perfection

Not checked

NewsLink could not identify one source study, so this claim was not compared against a paper.

Claim 5 of 6Not checkedThe story says adding quantum magic alone was not enough to improve results, and that the decoding procedure had to be matched to the scrambling method.View evidenceHide evidence

Not checked

NewsLink could not identify one source study, so this claim was not compared against a paper.

Claim 6 of 6Not checkedThe article describes the work as theoretical, based on mathematical models of idealized quantum systems, and says it was posted as a preprint on arXiv and not yet peer-reviewed.View evidenceHide evidence

Not checked

NewsLink could not identify one source study, so this claim was not compared against a paper.
