# Generate a random UUID
python -m qrngtools --type uuid

# Generate a 3x3 matrix of random floats
python -m qrngtools --type matrix --rows 3 --cols 3

# Generate a random permutation of a sequence
python -m qrngtools --type permutation --seq A B C D

# Generate a list of 10 random bits
python -m qrngtools --type bit_array --length 10

# Generate a list of 10 random floats

qrngtools

Quantum random number generation using IBM Quantum (Qiskit) and AerSimulator.

1. Environment Setup (Recommended)

Create and activate a clean Python environment:

Windows PowerShell:

python -m venv .venv
.\.venv\Scripts\Activate.ps1

Windows Command Prompt:

python -m venv .venv
.\.venv\Scripts\activate.bat

Linux/macOS:

python3 -m venv .venv
source .venv/bin/activate

2. Install the Package

Install from PyPI:

pip install qrngtools

3. (Optional) Set Up IBM Quantum Cloud Backend

Set your IBM Quantum API token as an environment variable:

Windows PowerShell:

$env:IBM_QUANTUM_TOKEN="your_token_here"

Windows Command Prompt:

set IBM_QUANTUM_TOKEN=your_token_here

If the token is set and the IBM provider is available, the package will use the IBM Quantum cloud backend. Otherwise, it defaults to AerSimulator (local quantum simulation).

4. Usage

Import and use the API functions:

from qrngtools import get_random_bit, get_random_bits, get_random_int, get_random_float, get_random_string

# By default, functions return only the random value
print(get_random_bit())      # 0 or 1
print(get_random_bits(8))    # e.g. '01101001'
print(get_random_int(100))   # random int in [0, 100)
print(get_random_float())    # random float in [0, 1)
print(get_random_string(10)) # e.g. 'aB3kLmP9Qz'

# To get the randomness source as well, pass with_source=True
bit, source = get_random_bit(with_source=True)
print(bit, source)           # e.g. 1, 'quantum' or 'system'

5. CLI Usage

Generate a quantum random integer from the command line:

python -m qrngtools

6. Fallback

If Qiskit or AerSimulator is unavailable, the package automatically falls back to system randomness.
