The Grothendieck Game and Self-Testing Continuous Groups
Alexander Kulpe, Giulio Malavolta, Simon Schmidt +1
Self-testing certifies quantum states and measurements from observed correlations alone, without requiring a description of the devices that produce them. In this work we establish…
Computational Monogamy of Entanglement and Non-Interactive Quantum Key Distribution
Alex B. Grilo, Giulio Malavolta, Michael Walter +1
Quantum key distribution (QKD) enables Alice and Bob to exchange a secret key over a public, untrusted quantum channel. Compared to classical key exchange, QKD achieves everlasting…
A bound on the quantum value of all compiled nonlocal games
Alexander Kulpe, Giulio Malavolta, Connor Paddock +2
A cryptographic compiler introduced by Kalai et al. (STOC'23) converts any nonlocal game into an interactive protocol with a single computationally bounded prover. Although the com…
Permutation Superposition Oracles for Quantum Query Lower Bounds
Christian Majenz, Giulio Malavolta, Michael Walter
We propose a generalization of Zhandry's compressed oracle method to random permutations, where an algorithm can query both the permutation and its inverse. We show how to use the…
Exponential Quantum One-Wayness and EFI Pairs
Giulio Malavolta, Tomoyuki Morimae, Michael Walter +1
In classical cryptography, one-way functions are widely considered to be the minimal computational assumption. However, when taking quantum information into account, the situation…
A Computational Tsirelson's Theorem for the Value of Compiled XOR Games
David Cui, Giulio Malavolta, Arthur Mehta +5
Nonlocal games are a foundational tool for understanding entanglement and constructing quantum protocols in settings with multiple spatially separated quantum devices. In this work…
