11. Ising model tutorial for
beginners on ipython

12. To create quantum computing community for
industry
Community and eco system is the most important to improve the whole system.
We need some components to maintain the community and industry.
SDK
Software development Kit
Tutorials on SDK Communication tools and place to disscuss
Hardware
Middleware to handle
the hardware
Application and Software based on the SDK
Cloudsystem to deliver the
service
Simulators
libraries

13. For national project we don’t need full component
If we just accomplish the research project we don’t need a lot.

14. QC
SDK is a userside python based software stack
Installing SDK into the user’s PC handling the process to the qc machine.
And basically it contains basic simulator of quantum computer inside it.
Application is working on this SDK

15. Simulator?
Usually users using simulator to develop the application before send
the data to the actual quantum computing machine. The simulator
simulate the quantum computing effect efficiently for a small size of
qubits.

16. The process to develop applications
Applications developed with simulator first and sent to the qc at last.

17. QC
Quantum Classical hybrid algorithm
SDK handle the Quantum-Classical hybrid algorithm using inside/outside simulator
and quantum computer.

There are many types hybrid algorithms for quantum computer.

Hybrid algorithm reduce the error of the existing quantum computer for NISQ era.

19. The QC service is provided through cloud.
Basically quantum computer is placed inside labs and the calculation provided
through cloud system which controlling user auth and job schedules. Users and
system communicate each other through API interface.

HPC simulator and Quantum computer need

Inside the lab near Quantum computer or HPC simulator, need some basic PC
systems to handle job.

21. Graphic based user interface built on API
Graphic based user interface like a quantum circuit to control with mouse or touch
panels is located on internet built on the API specification. The GUI interface is not
installed on the user’s PC, we just use it through basic browser.

The robustness guaranteed by some job schedulers, hpc simulator and userside

23. User tend to use qc with a lot users and tutorials.
Basically SDK is written in english language because the english user is the most
over the world. If you want to gather domestic users like inside Japan, you need to
write the basic documents on Japanese language.

24. Basic SDK located on pip and github
Usually users acquire software from github and quick installing package system
installed inside their computer like “pip” based on python.
Install
git clone https://github.com/Blueqat/Blueqat
cd Blueqat
pip3 install -e .
or
pip3 install blueqat

25. The hardware and software partners
Startups usually contract partnership with hardware providers. Software startups
have a lot of clients on quantum computing projects.

26. Summary : The whole economy
The hardware company provides hardware. The software company is using it
providing solution for their clients. The hardware and software service providers
have their own community to get feedback from the community and improving the
service. SDK is provided for free and application and hardware is usually provided
with prices.
