Directionality of Time in Quantum Computing

Abstract

Special Relativity suggests that the "arrow of time" may not be unidirectional. In experiments with potential far-reaching consequences for quantum computing, quantum entanglement between photons has recently been proved to be created "a posteriori" after the entangled particles have been measured and may no longer exist. "Quantum steering into the past" may enable linking input and output of quantum computers, allowing a quantum computer to start calculating in the past a problem defined by an input that will only exist in the future. Breaking the directionality of causality and time opens immense perspectives for new computational mathematics and probability.
