Quantum computer is one of the technologies that are always 10 years away. But 2017 can be the year when quantum computers will change the world.
IT giants like Google and Microsoft have hired a host of leading lights, and have set challenging goals for this year. Their ambition reflects a broader transition taking place at start ups and academic research labs alike: to move from pure science to engineering.
“People are really building things,” says Christopher Monroe, a physicist at the University of Maryland in College Park who co-founded the start-up IonQ in 2015. “I’ve never seen anything like that. It’s no longer just research.”
How quantum computer are so powerful compared to normal computers
Quantum computers use quantum bits, also called qubits, to encode information as 0s, 1s, or both at the same time, rather than storing information using bits 0s and 1s as a normal computer do. A qubit can be 0 and 1 at same time which is known as superposition. This superposition of states—along with the other quantum mechanical phenomena of entanglement and tunneling—enables quantum computers to manipulate enormous combinations of states at once which makes a quantum computer 3,600 times more powerful than a super computer.
