"How to factor 2048 bit RSA integers in 8 hours" ... in 2019 ... scirate.com/arxiv/1905.09749

We need stronger .

Let me clarify. This is a demonstration of the math behind the factorization problem. Approaches have dropped the requirement from billions of qubits to ~20million to factor 2048-bit RSA in 8 hours.

To be clear, the current leader in quantum computing has a 72 qubit machine. We've got a ways to go before things are truly broken, but advances that drop the requirement this many orders of magnitude just bring us closer a future where ":crypto is fatally broken."
