Sometimes Quantum computers do not need to distinguish between cause and effect at all | NextBigFuture.com

Researchers have shown that a quantum computer does not need the arrow of time like a classical computer. In some cases, it’s as if the quantum computer doesn’t need to distinguish between cause and effect at all. The new work is inspired by an influential discovery made almost ten years ago by complexity scientists James Crutchfield and John Mahoney at the University of California, Davis. They showed that many statistical data sequences will have a built-in arrow of time. An observer who sees the data played from beginning to end, like the frames of a movie, can model what comes
