Thought I'd compile this here so others can take advantage of it.

As of 2026-03-02, the state of the art in quantum decryption has cracked a:
- 22-bit RSA key
- 6-bit elliptic curve key
The IBM QC that cracked the 6-bit key uses 133 qubits.
Some new research suggests that RSA-2048 could be cracked with as "few" as 100,000 qubits.
Breaking encryption with a quantum computer just got 10 times easier
The commonly used RSA encryption algorithm can now be cracked by a quantum computer with only 100,000 qubits, but the technical challenges to building such a machine remain numerous

Such a machine...is not feasible to build any time soon.
So when your CISO or a vendor starts going off about "post-quantum" security, feel free to use this to remind them that we still have SMB1 in some places and Telnet in others. Plenty of work to do around the house.

22 bit RSA I think most people’s phones could fart and crack that too

@mttaggart it's crazy that this is the controversial, minority opinion in cybersec....

@mttaggart Note also the "expensive pre- and postprocessing" for the RSA "break". So far, each and every quantum factorisation has used massive trickery, which ensures that these "results" won't generalise. I haven't yet had a look at this one, but given that quantum annealing has had no demonstrable benefit over conventional computers, I think the chances are high.

@hweimer These weren't strictly Shor's, but I take your point.
