Exponentially decreasing critical detection efficiency for any Bell inequality
Nikolai Miklin, Anubhav Chaturvedi, Mohamed Bourennane +2
We address the problem of closing the detection efficiency loophole in Bell experiments, which is crucial for real-world applications. Every Bell inequality has a critical detectio…

How to avoid (apparent) signaling in Bell tests
Massimiliano Smania, Matthias Kleinmann, Adán Cabello +1
Bell tests have become a powerful tool for quantifying security, randomness, entanglement, and many other properties, as well as for investigating fundamental physical limits. In a…
