Upper bounds for the clock speeds of fault-tolerant distributed quantum computation using satellites to supply entangled photon pairs

Upper bounds for the clock speeds of fault-tolerant distributed quantum computation using satellites to supply entangled photon pairs

Despite recent advances in quantum repeater networks, entanglement distribution on a continental scale remains prohibitively difficult and resource intensive. Using satellites to distribute maximally entangled photons (Bell pairs) between distant stations is an intriguing alternative. Quantum satellite networks are known to be viable for quantum key distribution, but the question …
