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...

We should also thank the team for this exceptional #quantum cake! More details in the blog post below 👇🍰😋
