Backends
A simulator lets you test a quantum experiment without real quantum hardware. Local simulators are free and ready to use.
Backend Availability
Runs in your browser or on the local server. Always free.
The AWS Braket SDK is not installed. Install @aws-sdk/client-braket and set QUANTUM_AWS_* environment variables.
Physical quantum processors are not available. Safety gates prevent all QPU access.
Cloud simulator not configured
Missing environment variables: QUANTUM_AWS_REGION, QUANTUM_AWS_ACCESS_KEY_ID, QUANTUM_AWS_SECRET_ACCESS_KEY, QUANTUM_AWS_BRAKET_S3_BUCKET. Set these in your server environment to enable AWS Braket integration.
Also requires the package @aws-sdk/client-braket to be installed.
Real hardware blocked
Safety gates are active: cost-safe mode, disable-real-hardware, and require-simulator-first are all enabled. No paid QPU execution is possible. Real hardware will remain disabled until these gates are explicitly removed.
