The researchers whose trusted networks rank it highest, strongest advocate first. Every researcher gets a different order.

Unconditional room-temperature quantum memory (2011, background): “The natural bound that a quantum memory must overcome is the classical limi”
Quantum interface between light and atomic ensembles (2008, background): “In particular, Grosshans and Grangier (2001) emphasize the importance of a benchmark F1→2 given by the maximal fidelity achievable in a 1 to 2 cloning machine.”
Advances in quantum cryptography (2019, unknown): “A realistic case is the so-called entangling cloner [374] where Eve prepares a TMSV state with variance ω = n̄+1 and mixes one of its modes with the signal mode via a beam-splitter with transmissivity η, therefore resulting in a thermal-loss channel.”
Quantum teleportation on a photonic chip (2014, background): “The non-ideal beam-splitting ratios reduce the quality of the entanglement in the circuit and immediately reduce the achievable fidelity to around 90% - a figure which still exceeds the cloning limit of F = 5/6 required for secure communication [26, 27] but is still below the fidelity of 99% thought”
