Unlike traditional computers that rely on bits of information that can be in one of two states (1 or 0), quantum computers manipulate qubits, or units of information tucked inside subatomic particles. That means, they follow the wacky laws of quantum mechanics and so can be in two states at once. This ability allows quantum computers to theoretically store exponentially more information than your everyday laptop. Live Science is here to dissect the latest achievements and discoveries in this bizarre quantum world of computing.
The new phase was made by firing lasers at 10 ytterbium ions inside a quantum computer.
Reference Quantum computing is millions of times faster than traditional computing. These computers are able to do in seconds what would take millennia for our most powerful supercomputers to pull off today.
Researchers say the new network will be unhackable and able to coordinate systems to unprecedented levels. Many of the deeper implications, however, cannot be foreseen.
A remarkably simple change in the codes used to correct errors in quantum computers could half the number of destabilizing mistakes in these systems.
"Jiuzhang" would be the most powerful quantum computer in the world, capable of performing some tasks 100 trillion times faster than the world's fastest supercomputers.
A new online training course introduces students to quantum concepts, including superposition, qubits, encryption and many others.
We're one step closer to having quantum internet, but wait, what is quantum internet?
Google claims quantum supremacy – IBM says not so fast. One researcher explains why he doesn't see quantum computers outpacing classical computers any time soon ... and maybe not ever.
