Abstract: Equivariant quantum graph neural networks (EQGNNs) offer a potentially powerful method to process graph data. However, existing EQGNN models only consider the permutation symmetry of graphs, ...
Microsoft’s ambitious plan to build a commercial quantum supercomputer by 2029 is facing renewed scientific scrutiny after a new peer-reviewed critique challenged the company’s earlier Majorana-based ...
Abstract: The absence of real single-photon sources is a significant limitation to the experimental implementation of the BB84 quantum key distribution (QKD) protocol. When substantially attenuated ...
