SUMMARY
The discussion centers on the current limitations of storing single qubits, specifically in the context of the BB84 quantum key distribution protocol. It is established that storing unentangled qubits presents the same challenges as storing entangled qubits, with current technology unable to maintain a single qubit for more than a fraction of a second. Experts predict that significant advancements in this area may take another one to five years.
