I could not find the sign-up button.
Anyone can help me solve this problem.
Thank you!
Hey @YangLiu , do you already have an account for Xanadu Cloud? You should be able to sign in using this prompt.
If you don’t have an account yet and you need access to some of the hardware available via Xanadu Cloud, you can get in touch here. 
Are you looking to do something specific on quantum hardware?
