Access to Dwave Solvers
Has DWave changed the way to access the quantum solvers?
My token disappeared from the dashboard and the previous way that worked failed. I did not see any update in related documentation.
Below is the code I've been using.
Thank you for any hint on this.
from dwave.system import DWaveSampler, LazyFixedEmbeddingComposite
sampler = LazyFixedEmbeddingComposite(DWaveSampler(token=Leap_API_token))

Hello,
On January 22, 2025, free-trial access to D-Wave quantum and hybrid solvers was replaced with a new initiative: the Leap™ Quantum LaunchPad™ program.
Release notes: https://docs.dwavesys.com/docs/latest/doc_release_notes.html#launchpad
To apply to the new Leap Quantum LaunchPad program, complete the following form: https://www.dwavesys.com/quantum-launchpad/
The Leap Quantum LaunchPad program is an exclusive trial, and not all submissions will be accepted.
It seems i choose bad day to test the api too file "C:\Users\Dwave\3d-bin-packing\venv\Lib\site-packages\dwave\cloud\client\base.py", line 1098, in get_solvers

Is Dwave not allowing for personal dwave accounts? I don't have any institutional email id, how can I do that then ?
Hi team,
I am testing my environment and encountered an authentication error when executing the following command:
(dwave) $ dwave pingI have installed the SDK, but I suspect an issue with my configuration. Could you help me troubleshoot this?
Best,
Hello,
The dwave ping command requires an API Token to as it communicates with the D-Wave Solver API.
I hope this was helpful.
Hi, David.
Many thanks for your message.
The result of what I have done:
Optionally install non-open-source packages and configure your environment.
All optional packages already installed.
Authorizing Leap access.
Valid token found, skipping authorization.
Creating the D-Wave configuration file.
Using the simplified configuration flow.
Try 'dwave config create --full' for more options.
Updating existing configuration file: /Users/parfait/Library/Application Support/dwave/dwave.conf
Available profiles: defaults
Updating existing profile: defaults
Failed to fetch SAPI token from Leap API (Solver API token not available for users with trial access to the Leap service).
Solver API token []: xxxxxxxxxxxxxx (I changed it to do not share it publically)
Configuration saved.
My question is, can we execute anything with the trial access? I understood that the Leap service is not available for trial access.
Many thanks
Hello,
That's correct. There is no API access with the trial access.
The dwave ping and dwave config create commands are designed to set up API token access.
It is still possible to use some Ocean Tools resources, such as the classical computing libraries like dimod.
Hopefully this was helpful.
Please feel free to reach out with more questions.
Many thanks, David!
How could I have a subscription to the Leap service? Is it pay-per-use?
Many thanks,
Parfait

Hi,
I am a researcher and applied to the LaunchPad program around two weeks ago. When can I expect a response?
The estimated response time is approximately 10 business days. However, actual response times will vary based on the number of applications submitted.
