Back to the Future on a Quantum Computer: Demystifying Time Loops | Paradoxes Ep. 09

Imagine you could go back in time and meet your past self. Time-travel can lead to all kinds of paradoxes - but what happens when we try and model time-travel using quantum mechanics? In this video, Oxford PhD researcher Maria Violaris, together with her past self, explain how to resolve the famous Grandfather Paradox in quantum mechanics, by simulating a time-loop with a quantum computer. Maria shows how these "closed-timelike-curves", if they exist, would give quantum computers a huge boost in computational power. She also explains some open problems with time-loops that are yet to be resolved. Learn more at the Qiskit Blog: Blog post coming soon to   / qiskit  !
