Quantum Time Travel Paradox Solved: Study

If a person travels back in time and kills her own mother, well that’s pretty sinister—but it also creates for her an existential paradox. How does she exist if her mother doesn’t give birth to her?

Quantum computing theory was plagued by a similar paradox. It could be used to solve very complex mathematical problems, but to do so could seriously mess with time. An international team of scientists has developed a way, however, for quantum computing to use time travel without breaking causality...read more>>>...
