Sounds like a crackpot to be honest. QC doesn't work yet because of practical limitations, but individual blocks have been shown to work separately and even small computers [1]. In looking at his wording he may be addressing a straw man, because QC has never aimed to be a general purpose general computer. The universe is usually thought of as not deterministic. The deterministic interpretations out there come with huge problems: non-locality. Basically, that all particles in the universe are connected with a wave of sorts that acts instantaneously no matter the distance. But this is a philosophical distinction at best. Quantum computers work just fine. [1]https://www.technologyreview.com/s/609451/ibm-raises-the-bar-with-a-50-qubit-quantum-computer/ https://www.technologyreview.com/s/609451/ibm-raises-the-bar...
