Here’s how to generate a truly random number with quantum physics
- True randomness is hard to achieve in daily life due to predictable variables affecting traditional methods like coin flips, dice rolls, and cryptographic algorithms.
- Quantum physics offers a solution for true randomness that is unpredictable by any means in the universe.
- The Colorado University Randomness Beacon (CURBy) offers a unique way of generating truly random numbers using quantum mechanics concepts.
- CURBy leverages Bell test entangled photons to provide verified randomness at a quantum level.
- NIST developed true randomness generators based on Bell tests and quantum mechanics, aiming to offer a public service.
- The initial experiment produced 512 bits of true randomness, but researchers improved and automated the process.
- CURBy recorded a success rate of generating random numbers at 99.7% in its first 40 days.
- The generation process involves using a nonlinear crystal to create entangled photon pairs that are measured for polarizations to yield random bits.
- NIST processes the data from quantum measurements through a computer program to output 512 random bits for public use.
- CURBy allows users to access its randomness generation service on its website by inputting a list for shuffling based on quantum randomness.
- The utilization of quantum physics for random number generation simplifies the process compared to traditional methods, showcasing the power and utility of quantum concepts.
