quantum computer and quantum computing (5), other quantum computer players

 There are some other players in quantum computing. I am going to write this section little by little. 

There are a few big quantum computer players from China and they are showing great progress too. 

quantum computer and quantum computing (4), google quantum comptuer

 One hype of quantum computing definitely came from Google quantum computer since it once claimed the supremacy of quantum computing.  See this article:

https://techcrunch.com/2022/08/05/googles-quantum-supremacy-usurped-by-researchers-using-ordinary-supercomputer/

However, I did not have hands-on experience with google quantum computer at all. 

quantum computer and quantum computing (3), Amazon quantum computing

 The third quantum computer is the Amazon quantum computer.  Here it is the link:

https://aws.amazon.com/braket/

It is a little different from IBM quantum computer and it comes a little later than IBM quantum computer. However, because of the widely used AWS service, AWS quantum computing  is spreading fast and widely. 

It is easy to get an hands-on experience too.

quantum computer and quantum computing (2), IBM quantum computer

 The second quantum computer I encountered is the IBM quantum computer. It is a more generalized quantum computer and it is one of the mainstream quantum computers.

You can create a personal account https://www.ibm.com/quantum and build some toy quantum computing problem there.

quantum computer and quantum computing (1), D-Wave

I worked with quantum computing and quantum computers for a long while before. I always keep an eye in this area too. I am not researcher, instead a quantum computing users. So I am not going deep into this area, instead focusing on application and some hands-on experience with quantum computing. 

I will take a quick first route to write a few sections and gradually add more contents here. 

 My first contact with quantum computing is D-Wave, which is a specialized quantum computing-quantum annealing approach. I did some simulation on D-Wave quantum computer (it is really cool) and some research on the quantum annealing process too. 

Some people would say D-Wave is not really a quantum computer. However, thinking of quantum computers are not general purpose computers, so I don't agree with such assessment. 

Here is the link to D-Wave system.

In order to understand quantum computing, we need to know the basic qubit, which is the counterpart of bit of the conventional/classical computer. Bit has only two values 1 or 0 or on/off. Qubit could take infinite values in a 2D dimension, a.k, it has strength and direction.

There are three key ideas for qubit: superposition, entanglement, and interference.
