Ab initio simulation of spin-charge qubits based on bilayer graphene-WSe2 quantum dots

Published in npj 2D Materials and Applications 9 (1), 47, 2025

In this paper we investigated a WSe2 heterostructure and proposed a novel scheme two define hyperentanglement between charge and spin.

Dynamic rephasing in a telecom warm vapor quantum memory

Published in arXiv preprint, 2026

We introduce and experimentally demonstrate a dynamic rephasing protocol that counteracts Doppler dephasing in a telecom-band ORCA quantum memory, extending storage time by a factor of 50 while preserving GHz bandwidth and low noise.

Degree of tensor train varieties via integral geometry

Published in arXiv preprint, 2026

Using methods from integral geometry, we obtain a combinatorial expression for the degrees of tensor train varieties.
