Seth Lloyd: Quantum Machine Learning

Показать описание

Seth Lloyd visited the Quantum AI Lab at Google LA to give a tech talk on "Quantum Machine Learning." This talk took place on January 29, 2014.

Speaker Info:

Seth Lloyd is one of pioneers in the quantum information science with several seminal contributions to quantum computing, quantum communication, and quantum control. He developed the first quantum algorithms for efficient simulation of many-body systems at the quantum scale. He has also introduced the first realizable model for quantum computation and is working with a variety of groups to construct and operate quantum computers and quantum communication systems. Dr. Lloyd is the author of over a hundred and fifty scientific papers, and of `Programming the Universe,' (Knopf, 2004). He is currently professor of quantum-mechanical engineering at MIT.

Abstract:

Machine learning algorithms find patterns in big data sets. This talk presents quantum machine learning algorithms that give exponential speed-ups over their best existing classical counterparts. The algorithms work by mapping the data set into a quantum state (big quantum data) that contains the data in quantum superposition. Quantum coherence is then used to reveal patterns in the data. The quantum algorithms scale as the logarithm of the size of the database.

"I hope everybody is hearing these questions. These are all extreamly important questions."

I am crying inside right now.

These silent question-pauses are making me nutts.. Wish Google would bother with microphones or at least texting the questions into their videos.

- He considers himself a quantum mechanic.
- Your quanta are broken, we fix them.

The guy is fantastic :)

After Seth mentions the footnote from the 1929 paper, about alpha²+beta² = 1, thinking about complex numbers, it comes to mind that he is actually talking about the unit circle. As the total probability is always 1 or 100%, the radius of the complex number representing the total probability of the qubit being 0 or 1 needs to be 1, hence the unit circle, hence the quadratic members.

Very very lucid talk by legendary Seth Llyod! Unfortunately the queries by audiences are not audible.

I wonder what the microphone in the middle is for.... :p

thank you :) thanks for teaching!

That whiteboard looks like the Moses Tablets.

RafaelRodrigues-rxry

You'd hope Google, of all companies, would bring an electronic whiteboard for the guy to use, so that it can be projected overhead and shown clearly in the video. But nope.

It would seem we have moved to mapping interference patterns
as Quantum Symphonies. representing Complex Systems.

What a pity that we can not hear the questions.

Very interesting talk, too bad you couldn't hear the questions.

jnxmaster

Pretty sure at 58:35 and 58:37 he is saying "Graphene" not "Graphing"

"Seth Lloyd visited the Quantum AI Lab at Google LA" //Quantum AI labs are so trendy these days.

A lot of misinformation on this one... Prime example, the James Brown quote isn't from a concert, it's the intro to "Make It Funky":

(Bobby:)
What you gonna play now?
(James:)
Bobby, I don't know. But whatever I play, its got to be funky!
(Bobby:)
Yeah
