1/ One of the most common misconceptions about quantum computing is that Bitcoin won't be a prime target. People think, "If quantum computers can break Bitcoin, we have much bigger issues."

Let me explain why that's dangerously mistaken and why Bitcoin is truly the low hanging fruit for quantum computers. A thread…🧵

In our latest research, now available on ArXiv, we demonstrate #quantum error-detection at the individual qubit level through the encoding of an error-detected logical qubit in a fixed-frequency multimode transmon qubit, using dual-rail encoding. 🔗 https://t.co/2jqrrNewWv 1/4 🧵

NORAD was down for 18.5 hours over Y2K according to the people who had to fix it. Several banks crashed but they had staff on hand to fix and a lot of work done in advance.
There was a problem with the Year 2038 bug (see wiki) in Jan 18, 2008 and mortgages were recorded as being paid off in the early 1900s as soon as they were created. "buffer overflows" are still a common attack vector in hacking today, despite multiple layers of defenses.
That said to clarify two common misconceptions - some bugs are given a lot of noise and then we keep it quiet. Some bugs are not given enough noise and then the responsible parties avoid accountability. Quantum Computing vs Bitcoin is clearly the latter, and the devs may be sued for $2 trillion in Bitcoin losses by criminal negligence.
Sufficiently large quantum computers turn a known public key into the private key. 6 million BTC have known public keys. 6 million BTC could be taken and then sold, regardless of the wallet type or ledger or hardware since the info needed is already recorded in the Blockchain.

The people making the hardware are declaring they will have the attacker machines ready in 2027, so we should be completely migrated before then to have some safety.
I estimate that programming and migration, even rushed, would still take 2-4 years. To be safe with a margin of time, the code should have been decided, agreed and written in 2023. Miners may need to replace their hardware, depending on what part does the tx verification. (Software upgrade to the mining pool, with support from existing code already written is more likely, but we should estimate both until every decision is mapped out.)
The code has not been agreed. It has not been written. It has not even been discussed well. BIP360 is the best candidate for a discussion about cryptography, as a soft fork. I support all legitimate paths to quantum safety, I support #BIP360 despite reservations. Some choices of cryptography would prevent transactions being performed because the signatures are 50kb of data each.
I am happy to explain some details, but this is probably already too long to introduce the topic.

Title: Multipartite entanglement distribution in Bell-pair networks without Steiner trees and with reduced gate cost

Siddardha Chelluri, PhD student in Johannes Gutenberg University in Mainz

Abstract: GHZ states are useful for quantum key distribution (QKD) and other secure communication tasks. We focus on generating these states from networks of Bell pairs. Although an existing protocol achieves this optimally in terms of time and resource use, it requires up to quadratic gate operations and solving a NP hard computational problem. Since gate operations are noisy, reducing their number is important, we introduce a protocol uses only a linear number of gates, works on any network structure, and avoids NP-hard challenges. We also performed numerical simulations on several network models, showing that our method significantly lowers gate costs in practice. (The finer details are in: arXiv:2412.04252)
