strangeworks-matlab
The strangeworks-matlab package allows MATLAB users to communicate with the Strangeworks platform.
This allows users to submit jobs to gate based quantum hardware as well as a wide range of alternative compute providers, see full catalog.
Installation
A user must go through the following steps to be able to run jobs
- Download and authenticate Matlab, free trials available. Skip this if you already have a license.
- Download and install the quantum computing package
- Download Strangeworks.mltbx from File Exchange. Double click to install with Matlab package manager
- Sign up for free to our platform
- Add the free IBM runtime resource. For other resources, please visit the Strangeworks catalog
- Put in your apiKey from the homepage and resource id from the resource page and run the example script
example_ibm.m

Usage
IBM
Here's a simple example of creating a Bell state with IBM.
Before running follow the installation steps above:
apiKey = '';
resource_slug = "";
sw = strangeworks().authenticate(apiKey);
sw = sw.get_resource(resource_slug);
fprintf("Product %s \n", sw.product_slug)
backends = sw.backends();
for i = 1:length(backends)
fprintf("name=%s: remoteStatus=%s: id=%s \n",backends(i).name,backends(i).remoteStatus,backends(i).remoteBackendId)
end
gates = [hGate(1); cxGate(1,2)];
qc = quantumCircuit(gates);
shots = 100;
backend = "ibmq_qasm_simulator";
sw_job = sw.run(backend,qc,shots)
job_slug = sw_job.slug;
status = sw.status(job_slug);
fprintf("Job %s status %s \n", job_slug,status)
results = sw.result(job_slug);
sw.plot_histogram(results.hist)
