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.

In this post, we present the first practical milestone in implementing our research around TEEs and quantum cryptography.

In this blog post, we explore the development of cryptography, particularly in light of the paradigmatic changes brought about by quantum theory.

In this post, we build on our previous TEE research, and how to improve on the root-of-trust problem.

A note on the amount of non-locality that can be extracted using bipartite quantum resources, with an introduction to the important problem of quantifying non-locality.

In this post, we investigate how just a sparkle of quantum resources can greatly contribute to making TEEs secure.
