Agenda:

0:45 Intro

Lee Barford's job is to help to guide Keysight into the quantum computing industry and enable quantum computing experts

2:00 Why is quantum computing/a quantum computer important?

Clock rates for digital processors stopped getting faster around 2006 because of excessive heat

The processor manufacturers realized they needed more processor parallelism

Graphics processor units (GPUs) can be used as vector and matrix computational machines

Bitcoin utilizes this method.

6:00 What does the development of quantum computing and quantum computers mean for the future?

Gates being made with feature size of the digital transistor that have an effective gate length of down to 7 nm

Now we're pushing below 5 nm, and there are not many unit cells of silicon left in the layer. (one unit cell of silicon is 0.5 nanometer)

The Heisenberg uncertainty principle comes into play at this point because there are few enough atoms that quantum mechanical effects will disturb electronics.

These quantum mechanical effects include a superposition of states (Schrodinger's cat) and low error tolerance.

10:20 When will Moore's law fail? 

Quantum computing and quantum computers are one way of moving the computing industry past this barrier by taking advantage of quantum effects - engineering with them - to build a quantum computer that will do certain tasks much faster than today's computers.

15:20 Questions for future episodes:

What sort of technology does it take to make a quantum computer?

Where are current experiments probing?

Why are people funding quantum computing research and the building of quantum computers?

What problems are quantum computing (and quantum computers) working to solve?

17:30 Using quantum effects

Quantum computers probably won't be used in consumer devices because it currently requires a very low temperature and/or a vacuum.

18:00 The quantum computer's fundamental storage unit is a qubit (quantum bit). It can be in states 1 or 0 with some finite probability

19:00 You can set up a quantum register to store multiple potential qubits, and when read out, have an identical probability to be either of thes ... https://www.youtube.com/watch?v=_AZ0IqgAs6k
