Hi, blueqat has developed and distributed the blueqat SDK, a kit for developing software for quantum computers, for free.
https://github.com/Blueqat/Blueqat
Based on the desire to make more use of the blueqat SDK, we have developed a blueqat cloud that can be used immediately without installing or updating the SDK by simply logging in from your web browser and providing it for free. It's free to use and you get a cloud jupyter notebook environment with the blueqat SDK installed. Please use it by all means.
There is also a paid version for businesses that has enhanced security and allows you to share files with multiple accounts. You can use it from 100,000 yen (excluding tax) per month, so if you are interested, please consider the paid version. You can apply from the following.

The blueqat cloud service now comes under the blueqat quantum suite. You can visit the given blog for the details.
