A Quantum Money Solution to the Blockchain Scalability Problem

Andrea Coladangelo, Or Sattath

We put forward the idea that classical blockchains and smart contracts are potentially useful primitives not only for classical cryptography, but for quantum cryptography as well.…

Non-interactive zero-knowledge arguments for QMA, with preprocessing

Andrea Coladangelo, Thomas Vidick, Tina Zhang

We initiate the study of non-interactive zero-knowledge (NIZK) arguments for languages in QMA. Our first main result is the following: if Learning With Errors (LWE) is hard for qua…

Additive entanglemement measures cannot be more than asymptotically continuous

Andrea Coladangelo, Debbie Leung

In this short note, we show that any non-constant quantity defined on density matrices that is additive on tensor products and invariant under permutations cannot be "more than asy…

A two-player dimension witness based on embezzlement, and an elementary proof of the non-closure of the set of quantum correlations

Andrea Coladangelo

We describe a two-player non-local game, with a fixed small number of questions and answers, such that an -close to optimal strategy requires an entangled state of dimension $2^…

Smart contracts meet quantum cryptography

We put forward the idea that classical blockchains and smart contracts are potentially useful primitives not only for classical cryptography, but for quantum cryptography as well.…

Unconditional separation of finite and infinite-dimensional quantum correlations

Andrea Coladangelo, Jalex Stark

Determining the relationship between quantum correlation sets is a long-standing open problem. The most well-studied part of the hierarchy is captured by the chain of inclusions $\…
