ETH Zurich has demonstrated a method to amplify imperfect randomness into certifiably perfect random numbers using entangled superconducting qubits and Bell-tests, addressing a fundamental bias in conventional generators. This breakthrough, achieved over a 30-meter link, provides a critical foundation for future secure encryption protocols by ensuring that encrypted data cannot be partially decrypted even if the original randomness was flawed. The technology represents a tangible step toward resolving inherent limitations in digital security through quantum mechanical principles rather than creating randomness from scratch.
ETH Zurich’s Qubits Yield First Certifiably Perfect Randomness
ETH Zurich researchers achieved certifiably perfect random numbers via a quantum experiment using entangled superconducting qubits.
Researchers at ETH Zurich have, for the first time, generated certifiably perfect random numbers using a quantum experiment that could underpin future secure encryption methods. The team achieved this feat not by creating randomness from scratch, but by amplifying existing imperfect randomness using entangled superconducting qubits and a sophisticated “Bell-test” across a 30-meter link connecting two quantum chips. “It may seem strange, but it is almost impossible to create a perfect coin or a perfect die,” explains Renato Renner, highlighting the challenge…
