LESS is Even More: Optimizing Digital Signatures from Code Equivalence Open
LESS is a signature scheme based on the code equivalence problem that has advanced to the second round of the NIST PQC standardization process. While promising, the scheme suffers from relatively large signatures and moderate to slow signi…

Simulating open quantum systems with molecular spin qudits Open
Molecular nanomagnets represent a natural playground to implement qudits, i.e. logical quantum processing units with d > 2 states. These can provide a remarkable advantage to simulate open quantum systems compared to standard qubit approac…

A new path to code-based signatures via identification schemes with restricted errors Open
In this paper, we introduce a new variant of the syndrome decoding problem (SDP), called restricted SDP (R-SDP), in which the entries of the solution vector live in a fixed subset of the underlying finite field. We prove the NP-completenes…

Qudit-based quantum simulation of fermionic systems Open
Model Hamiltonians described by fermionic operators are ubiquitous in physics and chemistry, but the quantum simulation of their properties is challenging on near-term quantum computers. Indeed, for any problem with more than two connected…
