We're not finished with Quantum Computing for Computer Scientists and algorithms. However today we'll start seeing IBM's role in quantum computing.

2 Videos about IBM

3 IBM quantum computing

1. They have several quantum computers.

2. The older ones are freely available on the web.

3. Those have 5 and 15 qbits; see https://quantum-computing.ibm.com/

4. Note that you can put gates between only adjacent qbits.

5. You submit a batch job and get emailed when it runs.

6. IBM github site: https://github.com/Qiskit with

   1. a free simulator.

      It doesn't match all the physical complexity of the real computer, but it's a good start.

   2. and tutorials and presentations.

7. and a SW development framework. https://qiskit.org/

8. You can create a quantum computation program either by

   1. designing a circuit, or

   2. using a programming language.

4 Sites

1. https://qiskit.org/

   1. Install it on your machine.

   2. Create and run the demo program.

   3. Try the Getting Started tutorial.

      Since I'm still learning, I have to say circ.draw() not circ.draw('mpl')

2. https://www.ibm.com/quantum-computing/

   1. Browse around the website.

   2. Look at the topologies of some machines.

   3. Create an account for yourself.

   4. Play with the graphical composer.

   5. Submit a job.

   6. Look at the output.
