Local stabilizer

Recently, Nik Weaver proved a quantum analogue of the Ramsey theorem. Weaver&#x2019;s theorem states that for every positive integer k, there exists a positive integer <inline-formula> <tex-math notation="LaTeX">${n}_{{k}}$ </tex-math></inline-formula> ...

Efficient generation of spatially delocalised entangledstates is at the heart of quantum information science. Generally,flying qubits are proposed for long range entangling interactions,however here we introduce a bus-mediated alternative for this ...

Using pre-shared entangled states between the encoder and the decoder, we provide a previously unreported coding-theoretic framework for constructing entanglement-assisted stabilizer codes over qudits of dimension $p^k$ from first principles, where p ...${\mathbb{}}^{}$${}^{}$${\mathbb{}}_{{}^{}}$${}^{}$
