Summary

Quantum computers obtain superpowers by tapping into parallel universes, says Hartmut Neven, the founder and lead of Google Quantum AI. He explains how this emerging tech can far surpass traditional computers by relying on quantum physics rather than binary logic, and shares a roadmap to build the ultimate quantum computer. Learn how this fascinating and powerful tech can help humanity take on seemingly unsolvable problems in medicine, sustainable energy, AI, neuroscience and more.

0:02.0	Audio Collective.
0:04.0	You're listening to Ted Talks Daily where we bring you new ideas to spark your curiosity every day.
0:14.8	I'm your host, Elise Hugh.
0:16.8	You probably have heard of quantum computing already, but to really understand its promise.
0:23.0	The founder and lead at Google Quantum AI, Hartmut Nevin,
0:27.0	took the TED stage to break down how it works in practice.
0:31.0	After the break, better understand this revolution in computing by hearing it in action.
0:37.0	And now our TED Talk of the day.
0:42.0	I'm Hadmud. I lead Google Quantum AI. I have been working on quantum computing since 2012 and let me tell you why it is so intriguing.
0:53.0	Today's computers like your laptop or a server at the Google Data Center
0:59.0	operate on the binary logic of zeros and ones.
1:02.0	A quantum computer replaces the binary logic with the laws of
1:06.3	quantum physics. That gives it more powerful operations, allowing it to perform certain computations with way fewer steps.
1:15.0	So where does this superpower come from?
1:18.0	Quantum computing is the first technology that takes the idea serious
1:23.2	is that we live in the multiverse.
1:25.4	It can be seen as farming out computations
1:29.4	to parallel universes.
1:30.9	Let me explain.
1:32.1	In quantum physics, the key mathematical object to describe
1:37.1	many worlds is called superposition. You just need three bits to describe it.
