Google celebrates World Quantum Day with Doodle

April 14 (UPI) --Google celebrated World Quantum Day with a new Doodle Tuesday, April 14, which is a nod to Planck's constant, an equation that starts with the number 4.14.

"This Doodle features the Bloch Sphere, a visualization of how a qubit works," Google said on its website.

"While a classical computing bit is strictly 1 or 0, a qubit can exist in a blend of both, called a superposition," the description of the animated artwork noted. "By harnessing superposition, along with other quantum properties, quantum computers can solve specific, complex problems that are out of reach for today's supercomputers to solve."
