Quantum Randomness

Quantum Random Number Generator

True randomness derived from quantum vacuum fluctuations for cryptographic security

QRNG

Our Quantum Random Number Generator produces fundamentally unpredictable random numbers by measuring quantum vacuum fluctuations, delivering cryptographic-strength randomness at multi-Gbps speeds.

Quantum Vacuum Fluctuations

This QRNG exploits the fundamental unpredictability of quantum vacuum noise - the zero-point energy present even in empty space. By performing balanced homodyne detection on the vacuum state, we extract true randomness that is provably non-deterministic.

QRNG Technology

How our quantum random number generator works

Balanced Homodyne Detection

The QRNG uses balanced homodyne detection to measure the quadrature fluctuations of the quantum vacuum state. This approach provides several advantages over other quantum randomness extraction methods:

  • • High efficiency: Nearly all available quantum noise is converted to random bits
  • • Robustness: Insensitive to classical noise sources and environmental fluctuations
  • • Scalability: The same core technology supports from Mbps to Gbps generation

Quantum Advantage:

The vacuum state is the purest quantum state, with fluctuations that are fundamentally unpredictable according to quantum mechanics.
