David Elieser Deutsch, FRS is a British physicist at the University of Oxford. He is a Visiting Professor in the Department of Atomic and Laser Physics at the Centre for Quantum Computation (CQC) in the Clarendon Laboratory of the University of Oxford.
A new way to explain explanation
www.ted.com For tens of thousands of years our ancestors understood the world through myths, and the pace of change was glacial. The rise of scientific understanding transformed the world within a few centuries. Why? Physicist David Deutsch proposes a subtle answer.
On the infinite reach of knowledge | The TED Interview
It can be easy to believe that humans are insignificant. We’re specks of dust on a random planet in a vast universe. Less powerful than elephants. Fewer than ants. But David Deutsch believes that’s all beside the point, because humans possess one unique skill: attaining knowledge. David Deutsch – Oxford professor, father of quantum computing, recluse – convinced Chris years ago to take over leadership of TED with his ideas about knowledge. In this mind-bending conversation, the two dive into his theory that the potential reach of knowledge is infinite. They explore how knowledge first developed, why it sets us apart and what all of these heady concepts really mean for our present and future.

Many Worlds of Quantum Theory
Quantum theory is very strange. No act is wholly sure. Everything works by probabilities, described by a wave function. But what is a wavefunction? One theory is that every possibility is in fact a real world of sorts. This is the Many Worlds interpretation of Hugh Everett and what it claims boggles the brain. You can’t imagine how many worlds there would be.

Addendum
Deutsch gate
A single-gate set of universal quantum gates can also be formulated using the parametrised three-qubit Deutsch gate , named after physicist David Deutsch. It is a general case of CC-U, or controlled-controlled-unitary gate, and is defined as:
Unfortunately, a working Deutsch gate has remained out of reach, due to lack of a protocol. There are some proposals to realise a Deutsch gate with dipole–dipole interaction in neutral atoms.
I think that’s quite clear.
