The invention of quantum mechanics essentially modified how we perceive the pure world. In 1981, physicist Richard Feynman famously noticed that as a result of nature is quantum, we might ultimately must construct computer systems that function on those self same rules to really perceive it. Constructing these computer systems stays one of many biggest engineering challenges of our period.
At Google Quantum AI, our mission is to develop quantum computing for these complicated, at the moment unsolvable issues. We consider large-scale, error-corrected quantum computer systems would be the key to unlocking sure options for real-world issues — from discovering extra sustainable supplies to accelerating drug discovery — which can be past the attain of classical computer systems at this time.
Our focus stays on the long-term journey: transferring from experimental physics to the dependable, secure methods mandatory to supply these breakthroughs for everybody.
Visualizing the state of the qubit
At this time’s Google Doodle marks World Quantum Day by incorporating the Bloch Sphere into our brand. In quantum mechanics, the Bloch Sphere is a geometrical illustration of the state house of a two-level quantum system, or qubit.
Not like a classical bit, which is restricted to a binary state of 0 or 1, a qubit can exist in a mix of each. That is represented as a degree on the Bloch Sphere, permitting for a a lot bigger computational state house than conventional computing.
A significant hurdle at this time is sustaining these delicate states. Interplay with the setting causes “decoherence,” the place quantum info is misplaced to noise. Our present work is centered on constructing methods that may shield this info lengthy sufficient to carry out significant computations.
