Machine Learning with Quantum Computers

Last Updated on June 17, 2019

I recently watched a Google Tech Talk with Eric Ladizinsky who visited the Quantum AI Lab at Google to talk about his D-Wave quantum computer. The talk is called Evolving Scalable Quantum Computers and is great, I highly recommend it.

I’ve had quantum computing on my mind and another tech talk went by titled Quantum Machine Learning and I had to jump on it. The talk is by Seth Lloyd from MIT.

The talk starts out with a quick overview of quantum mechanics. He gives a mind bending example of a CD that holds about 10 billion bits that can be turned into a quantum state with a single photon. The problem is it’s not in a form that you can readily manipulate. This problem of developing natural systems that can innately quantum compute is one area that interests him.

The heart of the talk is the description of how to perform classical linear algebra operations using a quantum computer in order to get an exponential (logarithmic) speedup. This is desirable
