On the cryptographic potential of single-qubit rotations
Alex B. Grilo, Lucas Hanouz, Anne Marin
In the domain of quantum communication, cryptographic protocols often require users to have access to trusted qubit sources or detectors. Recently, it was shown that on an architec…
The Complexity of Stoquastic Sparse Hamiltonians
Alex B. Grilo, Marios Rozos
Despite having an unnatural definition, plays a central role in Hamiltonian complexity, e.g., in the classification theorem of the complexity of Hamiltonians by C…
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…
Amplifying Randomized Encodings & Applications
Pouria Fallahpour, Alex B. Grilo, Garazi Muguruza +1
A randomized encoding for a promise problem is a randomized reduction whose outcome distribution on input can be simulated within some distance , called privacy, using only…
Security of a secret sharing protocol on the Qline
Alex B. Grilo, Lucas Hanouz, Anne Marin
Secret sharing is a fundamental primitive in cryptography, and it can be achieved even with perfect security. However, the distribution of shares requires computational assumptions…
Quantum pseudoresources imply cryptography
Alex B. Grilo, Álvaro Yángüez
While one-way functions (OWFs) serve as the minimal assumption for computational cryptography in the classical setting, in quantum cryptography, we have even weaker cryptographic a…
