Nonlocality alone doesn’t always secure DIQKD. With full context revealed, some Werner correlations give zero key; with one-sided disclosure, secrecy can be recovered.

We believe the next revolution in security will be grounded not in computational assumptions, but in the laws of physics. Just as encryption enabled the explosion of the digital economy, physics driven security will enable the rise of the cyber physical economy. To achieve this, the infrastructure of trust must evolve: it must span bits and atoms, software and hardware, the digital and the physical. This is not an abstract aspiration; it is a decisive shift in how security must be conceived if we want innovation to flourish in the decades ahead.

At ESSLLI 2025 in Bochum, NeverLocal joined leading researchers to explore the power of sheaf theory across logic, language, and quantum mechanics. This is a short conceptual introduction on why sheaves can be used to model quantum phenomena.

At NapulETH 2025, NeverLocal stole the show by showcasing the first ever quantum experiment applied to the Ethereum blockchain.

We participated in the workshop on the island of Helgoland, marking the 100th anniversary of Werner Heisenberg's visit. Here is a brief account of our experience.

This blog post dives into how the GHZ state’s ‘spooky’ correlations enable quantum secret sharing, where a secret can only be revealed through collaborative decoding by all parties. Unlike classical methods, the protocol’s security stems from quantum nonlocality: the impossibility of explaining its correlations with hidden variables. We dissect how measuring the GHZ state produces outcomes that defy classical intuition, exposing a fundamental rift between quantum and classical physics.
