Compressing integer lists with Contextual Arithmetic Trits

Yann Barsamian, André Chailloux

Inverted indexes allow to query large databases without needing to search in the database at each query. An important line of research is to construct the most efficient inverted i…

Towards local testability for quantum coding

Anthony Leverrier, Vivien Londe, Gilles Zémor

We introduce the hemicubic codes, a family of quantum codes obtained by associating qubits with the $p$ -faces of the $n$ -cube (for $n > p$ ) and stabilizer constraints with faces of d…

Characterization of equivariant maps and application to entanglement detection

Ivan Bardet, Benoît Collins, Gunjan Sapra

We study equivariant linear maps between finite-dimensional matrix algebras, as introduced by Bhat. These maps satisfy an algebraic property which makes it easy to study their posi…

Composable security of two-way continuous-variable quantum key distribution without active symmetrization

Shouvik Ghorai, Eleni Diamanti, Anthony Leverrier

We present a general framework encompassing a number of continuous-variable quantum key distribution protocols, including standard one-way protocols, measurement-device-independent…

The BMM symmetrising trace conjecture for groups $G_{4}, G_{5}, G_{6}, G_{7}, G_{8}$

Christina Boura, Eirini Chavli, Maria Chlouveraki +1

We prove the BMM symmetrising trace conjecture for the exceptional complex reflection groups $G_{4}, G_{5}, G_{6}, G_{7}, G_{8}$ using a combination of algorithms programmed in different…

Golden codes: quantum LDPC codes built from regular tessellations of hyperbolic 4-manifolds

Vivien Londe, Anthony Leverrier

We adapt a construction of Guth and Lubotzky [arXiv:1310.5555] to obtain a family of quantum LDPC codes with non-vanishing rate and minimum distance scaling like $n^{0.1}$ where $n…
