Its syntax resembles the syntax of the C programming language and its classical data types are similar to primitive data types in C. One can combine classical code and quantum code in the same program. (wikipedia.org)

which argues explicitly that linear (modal) logic is a good formalization of quantum compuation. (ncatlab.org)

Here, we propose a hardware-efficient scheme to perform fault-tolerant quantum computation with high-rate qLDPC codes on reconfigurable atom arrays, directly compatible with recently demonstrated experimental capabilities. (arxiv.org)
