SoftQCOS™ CLI - Command-Line Interface for Quantum Circuit Optimization Service

CLI-QCOS - QCOS™ Command Line Interface

QCOS™ CLI — Command-line interface for the Quantum Circuit Optimization Service by SoftQuantus.

📦 Installation

pip install softqcos

This will automatically install the softqcos-sdk dependency.

🚀 Quick Start

# Configure API access once. No shell export required.
softqcos login

# Verify local config and API connectivity
softqcos doctor

# Show the SoftQuantus product welcome screen
softqcos welcome

# Show help
softqcos --help

# Run GHZ state optimization
softqcosrun ghz --qubits 20 --max-iters 100

# Run benchmark
softqcosbenchmark --qubits 5,10,20,50 --backend aer

# Show version
softqcos --version

# Show system info
softqcos info

The CLI stores credentials in ~/.softqcos/config.json with file mode 0600. QCOS_API_KEY and QCOS_API_URL still work and override the saved config for CI/CD jobs.

📋 Commands

softqcosrun

Run quantum circuit optimization.

softqcosrun ghz --qubits 50 --max-iters 100 --backend aer
softqcosrun vqe --qubits 4 --cost energy

Options:

• --qubits, -q: Number of qubits (default: 10)
• --max-iters, -i: Maximum iterations (default: 100)
• --backend, -b: Backend (aer, cirq, pennylane, braket)
• --method, -m: Backend method (automatic, statevector, matrix_product_state)
• --cost, -c: Cost function (correlation, bitstring, hybrid)
• --output, -o: Save results to JSON file

softqcosbenchmark

Run benchmarks across multiple qubit counts.

softqcosbenchmark --qubits 5,10,20,50 --backend aer --output results.json

softqcosinfo

Show system and environment information.

softqcosinfo

softqcos login

Configure the production API URL and API key interactively:

softqcos login

Non-interactive setup:

softqcos login \
  --api-url https://platform.softquantus.com \
  --api-key sq-live-...

Show config:

softqcos config

Reset config:

softqcos config --reset

Run diagnostics:

softqcos doctor

softqcos api

Stable JSON-first commands for agents, MCP bridges, Cursor, Copilot, and scripts:

softqcos api workspace init --json
softqcos api workspace discover --json
softqcos api job validate --input jobs/bell.qcos.json --json
softqcos api job plan --input jobs/bell.qcos.json --json
softqcos api run local --input jobs/bell.qcos.json --json
softqcos api result summary --input results/<run_id>/summary.json --json

These commands return structured payloads with status, capability, artifacts, metrics, and next_actions so AI agents can continue workflows reliably.
