Abstract

Entanglement distillation is an essential building block in quantum communication protocols. Here, we study the class of near-term implementable distillation protocols that use bilocal Clifford operations followed by a single round of communication. We introduce tools to enumerate and optimise over all protocols for up to $n=5$ (not necessarily equal) Bell-diagonal states using a commodity desktop computer. Furthermore, by exploiting the symmetries of the input states, we find all protocols for up to $n=8$ copies of a Werner state. For the latter case, we present circuits that achieve the highest fidelity with perfect operations and no decoherence. These circuits have modest depth and number of two-qubit gates. Our results are based on a correspondence between distillation protocols and double cosets of the symplectic group, and improve on previously known protocols.

Entanglement forms a key component for quantum networks, but is usually left imperfect by noise in experimental setups. By performing distillation on the noisy entanglement, one can compensate for this. Distillation trades off quantity with quality — it transforms noisy entanglement into a smaller amount of entanglement, but which is less noisy. Understanding how to perform such distillation is crucial for future networks. We use group theoretic tools to exponentially reduce the number of protocols, allowing us to find new and improved such protocols, that can be implemented in the near-term.
