Go watch the latest @VenturaLabs pod with @BeyondNISQ!

Careful though-- physical qubits ≠ progress. Actual progress is 🔥 The QPU industry's actual failure isn't the trajectory it's the access model. Research can't get QPU time without piles of money. (That's what @QuantumSN48 fixes on @bittensor). For the geeks-- a few important notes: → Dec 2023, IBM Condor hit 1,121 qubits. Missing from your chart. Same summit, IBM also announced Heron at 156 qubits with way better fidelity. Condor was a feasibility milestone, not a production target. Translation: industry decided quality is the new game. The whole industry pivoted that quarter. Charting physical qubits after that is charting a metric the field deliberately abandoned. IBM → Dec 2024, Google Willow crossed below-threshold error correction. First time in the field's 30-year history. A 101-qubit distance-7 code with logical error suppressed by Λ = 2.14 per code-distance increase, exceeding the best physical qubit's lifetime by 2.4x. Translation: Adding qubits now makes errors better, not worse. This is a key inflection. → Microsoft + Quantinuum: 12 logical qubits running with circuit error rate of 0.0011 vs. 0.024 for physical — 22x improvement. Translation: Logical isn't theoretical anymore. → Oxford Ionics: 99.99% two-qubit gate fidelity in 2025. Quantinuum: 99.9%+. Why is this important: Its squarely in the regime where error correction actually works. → RSA factoring requirement: dropped from 20 million qubits to ~1 million in 2025. Goalpost moved 20x closer in a single paper. → Quantinuum Helios shipped commercially Nov 2025 — 98 fully-connected trapped-ion qubits, >99.9% fidelity, with a new real-time control engine. This is production hardware, today. Right metrics to watch are logical qubits and gate fidelity. Both are on a tear. Charting physical qubit count past 2023 is like charting CPU GHz past 2005 (measuring the metric the industry deliberately stopped optimizing)







📢 Subnet Summer TAO X Spaces – May 1, 2026 | 10:00 AM CST Topic: TAO 2026 Ecosystem Developments, Conviction Mechanism & Subnet Opportunities We’re excited to announce the full speaker lineup for the first edition of our bi-weekly X Spaces series! Following the huge success of our previous session (over 1,000 live listeners), we’re back with an even stronger lineup of voices shaping the Bittensor ecosystem. Main Speakers & Topics 1. Gordon Frayne (@gordonfrayne ) Topic: Ecosystem updates and what’s coming next for TAO in the upcoming years. Gordon will kick things off with a comprehensive overview of the current state of Bittensor and his forward-looking thoughts on where the network is headed. 2. Mikecontango (@mikecontango ) Topic: Where is TAO going from here? A deep dive into the future trajectory of TAO, covering key developments, challenges, and opportunities on the horizon. 3. Macrozack (@macrozack ) Topic: The Conviction Mechanism Detailed explanation of this important upcoming feature and its implications for the network. 4. Gavin Zaentz (@gavinzaentz ) Topic: The Conviction Mechanism Continuing the discussion with additional insights, technical details, and real-world applications of the Conviction Mechanism. Subnet Owners Speaking: (Each subnet owner will present their subnet, current progress, use cases, and opportunities for miners and developers) Speaking Order: ▫️SN79 – @mvtrx_79 ▫️SN21 – @adtao_ppcrebel ▫️SN32 – @ai_detection ▫️TaoDx - @TaoDX_Official ▫️SN4 – @TargonCompute ▫️SN112 – @minotaursubnet ▫️SN63 & SN48 – @qBitTensorLabs This is your chance to hear directly from the builders and operators driving innovation across Bittensor’s subnets. Whether you’re a miner looking for new opportunities, a developer exploring collaborations, or an investor following the ecosystem, this session will deliver high-signal insights. Mark your calendars and see you in the Spaces!





Treasury Wallets are finally here. With @opentensor's latest update, the final barriers are gone and we’ve deployed the first-ever Treasury Contract on mainnet. Wallet: 5GvJQCF5nmnp9y8E6pGKaXqner8LPq7NjDJAgZbPrGaETnun This is a huge step for both Enigma and the #Bittensor ecosystem in building truly permissionless infrastructure. While we work with validators to test our subnet code, we’re dropping a live challenge with ~$5k on the line. Breaking Treasury Wallets Treasury Wallets enable zero-trust, winner-take-all incentive mechanisms—emission can safely be pooled in a single wallet, since it can only be removed when validator consensus is reached. This completely removes the ability for owners to run off with pooled miner emission. These wallets are powerful… but largely untested. Which makes them vulnerable. That’s where Enigma comes in -- a subnet designed to solve exactly this kind of problem. Your Challenge Break the Treasury Wallet. By any means necessary. If you can find a way to access it, the 2500 #SN63 alphas (~$5k) in the wallet are yours. You can find the full challenge details here: qbittensorlabs.com/enigma/challen…

Welcome to our live show! x.com/i/broadcasts/1…

qBitTensor Labs Live #13 We're excited to be back this week with another action-packed live for QBTLL #13 this Thursday 4/23! We have some major development updates for both @EnigmaSN63 and @QuantumSN48 and will take a deeper look into what's changing with the socials and our marketing strategy. We'll also have some discussion around recent events in the broader Bittensor ecosystem and of course, check in with the community! Make sure to tune in, you won't want to miss it. Please leave any questions for our Q&A in the comments or on Discord. We hope to see you on Thursday! 🩵
