An experiment claims to have invalidated a decades-old criticism against pilot-wave theory, an alternative formulation of quantum mechanics that eliminates the most baffling features of the subatomic universe.
Google’s 49-qubit chip will allow them to develop a 49-qubit quantum system that can solve problems that are far beyond the capacity of ordinary computers: Google calls this goal quantum supremacy. The 20-qubit system that the Google quantum computing team is now working on currently boasts a “two-qubit fidelity” of 99.5 percent. The higher the rating, …
