‘Arrow of time reversal’ on an IBM quantum computer
🎓 Academic research
MIPT · Argonne National Lab (Scientific Reports 2019) · Russia · USA · 2019
Designed an algorithm to send a two-qubit system’s state ‘back in time’, succeeding 85% of the time; at three qubits it dropped to 50%.
VerdictA local, microscopic ‘rewind’ needing external intervention.

Yamanaka factors & retinal ‘age reset’
🔬 Achieved by science
Kyoto Univ, Shinya Yamanaka (2006) · Harvard, Sinclair lab (Nature 2020) · Japan · USA · 2006–2020
In 2020, three factors (OSK) made old-mouse retinal ganglion cells epigenetically ‘younger’ and restored vision.
VerdictTime can be partly rewound at the cellular level.
