Follow-up expts from other groups (see Fig 4h of a recent Nature article) show results consistent with exploiting mobility-like effects in practice
Congrats to authors J Camps, O Crawford, G Gehér, A Gramolin, M Stafford, @marklt.bsky.social + thanks to Fujitsu!

This is, to our knowledge, the 1st paper to identify and characterise leakage mobility as an LRU. We compared mobility vs. other LRUs using fully quantum qutrit simulations on Fujitsu’s 39‑qubit simulator (Also: 🥈 in the Fujitsu Quantum Simulator Challenge!)
🧵3/4 www.fujitsu.com/global/about...
🪣Leakage moves qubits out of the computational space (|0⟩, |1⟩ → |2⟩). Long-lived leakage can destroy performance even with leakage-aware decoders. LRUs are needed to regularly remove leakage; mobility can serve that role.

👏We're excited to share our new paper showing that leakage mobility in superconducting qubits can itself act as a leakage-reduction unit (LRU) - i.e., moving leaked population so it can be flushed away: iopscience.iop.org/article/10.1...

Here’s why it matters…
🥳Excited to share our new paper: "Minimum Weight Decoding in the Colour Code is NP‑hard"
We prove there's no algorithm to find the best way to correct errors in reasonable time for the colour code
So, let’s focus on heuristic/approx algorithms: scirate.com/arxiv/2603.0... @marklt.bsky.social
This new feature tackles the challenge of "noisy" quantum data, providing robust, confident insights into your system's performance

💰Prioritise hardware improvements: identify the main error sources + understand how best to improve your hardware to reduce your error rates
💡Accelerate #QEC research: error budgeting offers a clear path to design more resilient codes + tailoring them to your specific hardware characteristics🧵3/4
Error budgeting transforms QEC optimisation from guesswork into a data-driven strategy, allowing you to:
🔬Identify primary error sources: you can pinpoint which physical error mechanisms (like gate errors, idle noise, or measurement errors) are holding back your #quantumcomputer 🧵2/4
🚀 Stop guessing, start optimising!
Improving #QEC performance can be like searching for a needle in a haystack, blindfolded! But what if you could ID your chip's performance bottlenecks?
Our OS Deltakit SDK does that with its NEW feature: Error budgeting in QEC! deltakit.riverlane.xn--com1-nf24c/4
🎉 It's publication day! 🎉
Congrats to the team for a new @prxquantum.bsky.social paper where their 'ghost protocol' speeds up QEC cycle speeds 10x for AMO qubits 👻

... instead of chasing “perfect” qubits in isolation, we should start building the MVP of fault-tolerant quantum computers now. These “first FTQC's” will help us test ideas, learn and scale faster. More info here: www.riverlane.com/first-ftqc-w...
Hi James, interesting post, thanks for sharing. Not wanting to throw another term at you, but our team wrote this whitepaper about 'First FTQCs' (not early! these are one step before) - the paper gives a full overview of what we mean, but, essentially...

And for @dulwichquantum.bsky.social, here's a meme to show how the LCD balances real-time speed, high accuracy and flexibility in hardware 🧪🐶
🧪🎉 Congrats to the team for their new Nature Comms paper on our Local Clustering Decoder (LCD)!
Until now, decoders have faced a hard trade-off:
⚡ fast but inaccurate
🎯 accurate but too slow
📈 or unable to scale
With LCD, they show this trade-off can be broken 💪

🔍 What if we said you could build a fault-tolerant #quantum computer with just 1,000 physical qubits? 🤔
It's not a trick question... it just requires a rethink on how we approach building #QuantumComputers – starting small with ‘the first FTQCs’ + scaling fast
