'supremacy' Achieved: Quantum Computer Notches Epic Milestone

For the first time, a quantum computer has solved a problem that a traditional computer, for all practical purposes, cannot, researchers reported today (Oct. 23) in the journal Nature . “A computation that would take 10,000 years on a classical supercomputer took 200 seconds on our quantum computer,” study co-author Brooks Foxen, a graduate student researcher in physics at Google AI Quantum in Mountain View and the University of California, Santa Barbara, said in a statement . “It is likely that the classical simulation time, currently estimated at 10,000 years, will be reduced by improved classical hardware and algorithms, but, since we are currently 1.5 trillion times faster, we feel comfortable laying claim to this achievement,” Foxen added. Related: How Fast Can Quantum Computers Get? Quantum computers store information using subatomic particles, which behave according to very different rules than the ones that govern our macro world. For example, quantum particles can exist in a “superposition” of two different states at the same time, and particles can be separated by light-years yet still be ” entangled ,” affecting each others’ properties. This weirdness is key to the incredible potential power of quantum computing . Because of the superposition phenomenon, quantum computers can store and manipulate far more information per unit …
