### Quantum Computing Video Lectures

Hey everyone, this month I have a ton of quantum computing video lectures, interviews and just short videos.

They include: Google's lectures on quantum computing. David Deutsch's lectures on quantum computing. Quantum games. Optimizations and search via quantum computers. Quantum cryptography. How do quantum computers work. Seth Lloyd's quantum computers.

Also my science friend Thomas from Belgium created these websites on famous scientists, take a look:

Google's Quantum Computing Video Lectures

Lecture description:
This tech talk series explores the enormous opportunities afforded by the emerging field of quantum computing. The exploitation of quantum phenomena not only offers tremendous speed-ups for important algorithms but may also prove key to achieving genuine synthetic intelligence. We argue that understanding higher brain function requires references to quantum mechanics as well. These talks look at the topic of quantum computing from mathematical, engineering and neurobiological perspectives, and we attempt to present the material so that the base concepts can be understood by listeners with no background in quantum physics.

David Deutsch Lectures on Quantum Computing

Video lecture topics:
The Qubit. Interference. Measurement. The Schroedinger Picture. A Quantum Algorithm. Grover's Search Algorithm.

Quantum Computing Games

Video description:
Imagine a game where two players go back and forth making moves and at the end of a fixed number of moves the position is either a win or a loss for the first player. In this case, if both players play best possible, it is determined at the first move who wins or loses. To figure out who will be the winner you need not look at all of the N final positions but only at N^0.753. I will show that with a quantum computer the exponent can be reduced to 0.5. The technique involves quantum scattering theory and illustrates how ideas from physics can be used to design quantum algorithms that outperform even best possible classical algorithms.

Revolutionizing optimization and search via Quantum Computers

Video description:
The presenter has built a system for solving hard optimization and search problems. The core of the system is a superconducting adiabatic quantum computer. Dr. Geordie Rose will review how the system works, and his company plans for deployment of a set of APIs for applications developers. His company is D-Wave.

Quantum Computing: Is the end near for the Silicon chip?

Short video description:
Dr. Dr Suzanne Gildert from Quantum Computer Institute of Physics explains quantum computing and death of silicon chips.

Practical Quantum Cryptography and Possible Attacks

Video description:
Quantum cryptography is actually about secure distribution of an encryption key between two parties. In this talk I give an introduction to practical quantum cryptography. I will describe the technical details of a few implementations, how the security of the distributed key might be compromised, and what steps can be taken to prevent this.

Scientific American Special: How Do Quantum Computers Work?

Video description:
Jargon is easy; metaphors are tough -- try describing quantum computers to folks who have never heard of them. One of our editors gives it his best shot in fifth episode of the Instant Egghead segment of Scientific American's new video podcast.

Seth Lloyd's Quantum Computer

Video description:
Professor Seth Lloyd talks about the world's smallest universe, quantum mechanics, quantum computers, and pushing Moore's Law beyond the capacity of the human brain.

Michio Kaku on Quantum Computing

Video description:
Short video of Michio Kaku explaining when quantum computers will be available.

Quantum Computers Explained By a Journalist

Video description:
This journalist tries to explain quantum computers in 2 minutes.

Quantum Computers and Parallel Universes

Video description:
Marcus Chown, author of Quantum Theory Cannot Hurt You: A Guide to the Universe, discusses the mechanics behind quantum computers, explaining that they function by having atoms exist in multiple places at once. He predicts that quantum computers will be produced within 20 years.

The Potential of Quantum Computing and Nanotechnology

Video description:
Malcolm Gillis, Ervin Kenneth Zingler Professor of Economics and past president of Rice University, explores the future of quantum computing and nanotechnology. James R. Von Ehr II, founder, chairman, and CEO of Zyvex Instruments, describes his vision of nanotechnology and what it can achieve.

Silicon Quantum Computer Research

Video description:
Researchers at the Kohei Itoh Group in Keio University are working to create the ultimate silicon computer, which does calculations using individual silicon atoms. The brain of a computer is made from silicon semiconductor integrated circuits, or silicon chips. In the semiconductor industry, to make silicon chips run faster and consume less power, people have worked to increase circuit integration. This trend is known as Moore's Law. However, if Moore's Law is pursued, by 2025, we will have reached the stage where a single silicon atom stores a one or a zero to do calculations in binary.

Have fun building a quantum computer!
