Introduction to Softquantus QCOS

Softquantus QCOS (Quantum Circuit Optimization Service) is a professional-grade platform for executing and optimizing quantum circuits at scale. Built by Softquantus for researchers, developers, and enterprises who need reliable, high-performance quantum computing infrastructure.

What is QCOS?

QCOS provides three ways to interact with our quantum execution infrastructure:

Interface	Best For	Features
Python SDK	Application development	Async support, Qiskit/Cirq integration, type hints
CLI	Scripting & automation	Batch processing, CI/CD, shell integration
REST API	Custom integrations	Language-agnostic, webhooks, enterprise features

Key Features

⚡ GPU-Accelerated Execution

Execute quantum circuits on NVIDIA A100 GPUs through the LUMI supercomputer, one of the world's most powerful HPC systems.

• Up to 100 qubits for state vector simulation
• 10-100x faster than CPU-based simulators
• cuStateVec backend for optimal GPU utilization

🔐 Enterprise Security

• API key authentication with role-based access
• Encryption in transit (TLS 1.3) and at rest
• SOC2-ready infrastructure
• Audit logging for compliance

📊 Transparent Pricing

Tier	Jobs/Day	Max Qubits	Max Shots	Price
Free	10	20	10,000	$0
Pro	100	50	100,000	$49/mo
Enterprise	Unlimited	100	1,000,000	Custom

Quick Start

Option 1: Python SDK

from qcos import QCOSClient

# Initialize client
client = QCOSClient(api_key="your-api-key")

# Execute a Bell state circuit
result = client.execute(
    qasm="""
    OPENQASM 2.0;
    include "qelib1.inc";
    qreg q[2];
    creg c[2];
    h q[0];
    cx q[0],q[1];
    measure q -> c;
    """,
    shots=1024
)

print(result.counts)
# {'00': 512, '11': 512}

Option 2: Command Line

# Install CLI
pip install qcos-cli

# Configure credentials
qcos configure --api-key your-api-key

# Execute circuit from file
qcos execute circuit.qasm --shots 1024

# View results
qcos status <job-id>

Option 3: REST API

curl -X POST https://api.softquantus.com/execute \
  -H "Content-Type: application/json" \
  -H "X-API-Key: your-api-key" \
  -d '{
    "qasm": "OPENQASM 2.0; ...",
    "shots": 1024
  }'
