Breaking RSA-2048 With 20M Noisy Qubit
An interesting paper was published on arXiv, the preprint server. Titled “How to factor 2048 bit RSA integers in 8 hours using 20 million noisy qubits,” the paper by Craig Gidney and Martin Ekerå combines previous techniques from Shor (1994), Griffiths-Niu (1996), Zalka (2006), Fowler (2012), Ekerå-Håstad (2017), Ekerå (2017, 2018), Gidney-Fowler (2019), and Gidney (2019) to significantly reduce the…
