The kind of bagel that ruins lesser bagels for you.
Summary
Researchers at ETH Zurich, led by Anatoly Kulikov, have developed a method to generate certifiably random numbers using a quantum Bell test. This approach addresses the fundamental challenge of proving that random number sequences are genuinely unpredictable, which is critical for secure communications like online banking and encrypted messaging. The work amplifies randomness from weak sources into high-quality, verifiable random bits using quantum mechanical principles.
