Justin Drake@drakefjustin·
Today is a monumentous day for quantum computing and cryptography. Two breakthrough papers just landed (links in next tweet). Both papers improve Shor's algorithm, infamous for cracking RSA and elliptic curve cryptography. The two results compound, optimising separate layers of the quantum stack. The results are shocking. I expect a narrative shift and a further R&D boost toward post-quantum cryptography. The first paper is by Google Quantum AI. They tackle the (logical) Shor algorithm, tailoring it to crack Bitcoin and Ethereum signatures. The algorithm runs on ~1K logical qubits for the 256-bit elliptic curve secp256k1. Due to the low circuit depth, a fast superconducting computer would recover private keys in minutes. I'm grateful to have joined as a late paper co-author, in large part for the chance to interact with experts and the alpha gleaned from internal discussions. The second paper is by a stealthy startup called Oratomic, with ex-Google and prominent Caltech faculty. Their starting point is Google's improvements to the logical quantum circuit. They then apply improvements at the physical layer, with tricks specific to neutral atom quantum computers. The result estimates that 26,000 atomic qubits are sufficient to break 256-bit elliptic curve signatures. This would be roughly a 40x improvement in physical qubit count over previous state-of-the-art. On the flip side, a single Shor run would take ~10 days due to the relatively slow speed of neutral atoms. Below are my key takeaways. As a disclaimer, I am not a quantum expert. Time is needed for the results to be properly vetted. Based on my interactions with the team, I have faith the Google Quantum AI results are conservative. The Oratomic paper is much harder for me to assess, especially because of the use of more exotic qLDPC codes. I will take it with a grain of salt until the dust settles. → q-day: My confidence in q-day by 2032 has shot up significantly. IMO there's at least a 10% chance that by 2032 a quantum computer recovers a secp256k1 ECDSA private key from an exposed public key. While a cryptographically-relevant quantum computer (CRQC) before 2030 still feels unlikely, now is undoubtedly the time to start preparing. → censorship: The Google paper uses a zero-knowledge (ZK) proof to demonstrate the algorithm's existence without leaking actual optimisations. From now on, assume state-of-the-art algorithms will be censored. There may be self-censorship for moral or commercial reasons, or because of government pressure. A blackout in academic publications would be a tell-tale sign. → cracking time: A superconducting quantum computer, the type Google is building, could crack keys in minutes. This is because the optimised quantum circuit is just 100M Toffoli gates, which is surprisingly shallow. (Toffoli gates are hard because they require production of so-called "magic states".) Toffoli gates would consume ~10 microseconds on a superconducting platform, totalling ~1,000 sec of Shor runtime. → latency optimisations: Two latency optimisations bring key cracking time to single-digit minutes. The first parallelises computation across quantum devices. The second involves feeding the pubkey to the quantum computer mid-flight, after a generic setup phase. → fast- and slow-clock: At first approximation there are two families of quantum computers. The fast-clock flavour, which includes superconducting and photonic architectures, runs at roughly 100 kHz. The slow-clock flavour, which includes trapped ion and neutral atom architectures, runs roughly 1,000x slower (~100 Hz, or ~1 week to crack a single key). → qubit count: The size-optimised variant of the algorithm runs on 1,200 logical qubits. On a superconducting computer with surface code error correction that's roughly 500K physical qubits, a 400:1 physical-to-logical ratio. The surface code is conservative, assuming only four-way nearest-neighbour grid connectivity. It was demonstrated last year by Google on a real quantum computer. → future gains: Low-hanging fruit is still being picked, with at least one of the Google optimisations resulting from a surprisingly simple observation. Interestingly, AI was not (yet!) tasked to find optimisations. This was also the first time authors such as Craig Gidney attacked elliptic curves (as opposed to RSA). Shor logical qubit count could plausibly go under 1K soonish. → error correction: The physical-to-logical ratio for superconducting computers could go under 100:1. For superconducting computers that would be mean ~100K physical qubits for a CRQC, two orders of magnitude away from state of the art. Neutral atoms quantum computers are amenable to error correcting codes other than the surface code. While much slower to run, they can bring down the physical to logical qubit ratio closer to 10:1. → Bitcoin PoW: Commercially-viable Bitcoin PoW via Grover's algorithm is not happening any time soon. We're talking decades, possibly centuries away. This observation should help focus the discussion on ECDSA and Schnorr. (Side note: as unofficial Bitcoin security researcher, I still believe Bitcoin PoW is cooked due to the dwindling security budget.) → team quality: The folks at Google Quantum AI are the real deal. Craig Gidney (@CraigGidney) is arguably the world's top quantum circuit optimisooor. Just last year he squeezed 10x out of Shor for RSA, bringing the physical qubit count down from 10M to 1M. Special thanks to the Google team for patiently answering all my newb questions with detailed, fact-based answers. I was expecting some hype, but found none.

And after voting that out too... 🇪🇺 ChatControl is back with a vengeance The Conservatives (EPP) are attempting to force a new vote TODAY (March 26) seeking to reverse the European Parliament's NO on indiscriminate scanning of ALL your private messages, emails and photos This is a direct attack on democracy and blatant disregard for your right to privacy If you're European contact your representatives now, with this handy form: #contact-tool" target="_blank" rel="nofollow noopener">fightchatcontrol.eu/?foo=bar#conta… If not, please share this tweet so more people see it and we can block the vote It's crazy they keep just bringing back whatever they want until it's passed! Obviously now we see the European Commission is controlled by powerful evil lobbying groups 👺

Just a month later and... 🇪🇺 ChatControl is back! Now they're trying to pass an even more far reaching ChatControl law through the back door, in a form even more intrusive than the originally rejected plan, without needing any of the EU countries votes The new proposal: - total mandatory surveillance of ALL text chats, emails and social media in the EU - obligatory registration of your ID/passport to your chat, email or social media account - minimum age requirement for chat, email and social media apps of 16 (!) The only way to stop this law is if EU countries veto it Read more here by @echo_pbreyer: patrick-breyer.de/en/chat-contro…

The previous frontend swap on Aave had a small dick energy hard limit of 30% slippage or the swap was reverted. Fortunately, for the low price of 8 figures of fees diverted, -60% on the token and a killed DAO. Users can now enjoy the big DeFi energy of 99% slippage. #L35" target="_blank" rel="nofollow noopener">github.com/aave/aave-v3-p…

Mass surveillance and censorship are escalating in many countries right now. There is a global attack on secure encrypted communication. Often, authorities, politicians, and tech companies work together to push for new laws. One example: when Ashton Kutcher (yes, the actor), through his tech company Thorn, tried to introduce total surveillance of all EU citizens through undemocratic and corrupt methods. First, Ashton Kutcher convinced the EU Commission that they could scan everything on an EU citizen’s phone or computer (messages, photos, emails, phone calls, all of it) for child sexual abuse material without, at the same time, looking at the content of other types of communication. And then? And then EU Commissioner Ylva Johansson presented the legislative proposal called Chat Control, which aimed to scan everything on all EU citizens' phones and computers (including conversations in end-to-end-encrypted messaging services). The message from the Commission was: we will only search for child sexual abuse material (CSAM). And then? And then experts from all over the world explained to her that the kind of scanning she was talking about (as Ylva described it: a drug-sniffing dog that can detect illegal content in a message without reading the message) simply cannot be done safely, and that Chat Control would mean the end of privacy and pose a security threat to all Europeans. Ylva responded with: “what about the children?” And then? And then it was revealed that Thorn, the organization founded by Ashton Kutcher and which had been lobbying for Chat Control from the beginning, was selling the kind of scanning technology that could be used for Chat Control – despite being registered as a charity organization in the EU’s lobbying registry. And then? And then it was revealed that Thorn, together with the EU Commission, had also started and funded “children’s rights organizations” that had supported the proposal. What appeared publicly to be charitable organizations were in fact lobby groups. And then? And then it was revealed that Europol wanted unlimited access and wanted to use the scanning for more than just child abuse crimes, saying that all data – also unfiltered and innocent material – should be stored because it “could at some point be useful to law enforcement”. And then? And then it was revealed that employees at Europol had joined Thorn, to lobby their old colleagues. And then? And then politicians in Brussels wanted to exempt themselves from the scanning. And then? And then the European Parliament, in an almost historic consensus, voted against the proposal and called Chat Control nothing but mass surveillance. As one of the members of the parliament said: “The Commission wasn’t focusing on protecting children but wanted mass surveillance.” And then? And then The Council of the EU (law proposals must go through both the Parliament and the Council), after three years of negotiation, finally reached a common position on Chat Control. The requirement for mandatory scanning (including end-to-end encrypted messaging services) was removed, which is a major victory, but several problematic elements remain in the Council's position. For instance, the Council wants to demand ID Control to use messaging services (including end-to-end encrypted). And then? And then, in 2026 the final negotiations began, between the European Commission, the European Parliament, and the Council of the EU. At the same time, the European Commission is working on a Plan B, through the initiative Going Dark/ProtectEU, where they once again try to force total surveillance (this time organized crime is the excuse) on the citizens of the EU.
