Have you signed up for this year’s #unitaryHACK? Our challenge focuses on Deltakit, our open-source toolkit for #QuantumErrorCorrection, with 4 issues for hackers to tackle (and some cash bounties! 💰) Find out more about the hack from @unitary.foundation here: unitaryhack.dev #quantumcomputing

We’re thrilled to announce that our collaborative research with @rigetti.bsky.social on real-time, low-latency quantum error correction (QEC) has been published in Nature Communications. 🚀 Huge congratulations to the researchers and engineers at Riverlane and Rigetti who made this possible! 🧪🧵1/3

This research marked the world’s 1st low-latency QEC expt on hardware, showing evidence that we can decode errors fast enough to keep up with the rapid cycle times of superconducting qubits Why was this important for the industry? 🧪🧩 In this experiment, we solved a vital piece of the puzzle...🧵2/3

... demonstrating a physical operation conditional on an error-corrected logical measurement. This allowed us to measure the full decoding response time, accounting for everything from data movement and syndrome conversion to the final feedback loop. 📖 www.nature.com/articles/s41... 🧪🧵3/3

Simulating non-computational errors just got faster⚡️ Noncomputational errors pose a significant challenge for quantum error correction, are hard to simulate and account for during decoding. We’ve released Deltakit-Stim to fix this. Deltakit-Stim... 🧵1/2

😔 Missed the #APSMarch Meeting last month? We've got you covered!

 Our team gave their insights into the event, including: 🟢 The industry's first end-to-end real-time #QEC demo 🟢 Why latency is now the defining bottleneck 🟢 Our partner integrations and plans

 🔗 www.riverlane.com/news/aps-mar...

On #WorldQuantumDay, Joan explained why the decoder is the beating heart of #QuantumErrorCorrection 💓 The blog post explores why real-time decoding matters, Riverlane’s approach to adaptive decoding, and NVIDIA’s latest "Ising" model (announced yesterday) 🧪🔗 www.riverlane.com/blog/why-the... #QEC

🎉 Happy #WorldQuantumDay! Today, we celebrate the science driving the next computing revolution and reflect on our highlights from an incredible year at Riverlane👇 If you want to help make utility-scale #quantumcomputing possible, we’re hiring: www.riverlane.com/jobs

New results! We ran the #Google Willow dataset (1M rounds of continuous QEC) through our #QEC stack & hit: ⚡Mean latency 16.32 µs (🎯 20 µs) ⚡Up to 10× faster processing v Google's published numbers ⚡Consistent, stable performance across every round 🧪 More info: www.riverlane.com/news/riverla...

#QuantumErrorCorrection is hard, but a softer approach can help! Instead of relying on 0/1 outcomes, soft decoders use rich analogue readout data to better judge when a qubit measurement is uncertain, leading to stronger error suppression with fewer qubits 🔗 iopscience.iop.org/article/10.1...

🪣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. Read our non-tech summary: www.riverlane.com/press-releas... 🧵2/4
