Bell Test

Definition ∞ A Bell Test is a specific experimental setup designed to verify the predictions of quantum mechanics concerning entanglement. It is used to confirm that particles are indeed correlated in ways that cannot be explained by classical physics. The test involves measuring entangled particles at spatially separated locations, with the measurement settings chosen randomly and rapidly after the particles have separated. This process is crucial for establishing the non-classical nature of quantum correlations, a foundational concept underpinning many advanced cryptographic protocols and distributed ledger technologies.
Context ∞ Discussions surrounding Bell Tests in the context of crypto news often arise when new research or applications in quantum cryptography are announced. The ability to demonstrate genuine quantum non-locality, as confirmed by Bell tests, is essential for developing provably secure cryptographic systems, which are critical for the long-term security of digital assets and blockchain infrastructure. Advances in experimental quantum physics, validated by these tests, directly inform the development of next-generation security paradigms in the digital asset space.
