Fran J H Heras @fjhheras.bsky.social · 13/10/2026Spacetime cost (qubits × runtime) is often what decides whether an algorithm can actually run on early fault-tolerant hardware. Reducing it for building blocks will enable higher-level quantum algorithms. 100 1
Fran J H Heras @fjhheras.bsky.social · 13/10/20262. We used Argon to discover a quantum arcsin subroutine that cuts spacetime cost by more than 100x compared to the published quantum CORDIC baseline. 100 1
Fran J H Heras @fjhheras.bsky.social · 13/10/20261. We used Argon to translate an internal version of our quantum error correction decoder, AlphaQubit, into a single, highly optimized hardware “megakernel,” nearly doubling inference throughput. Speeding up decoding is crucial, as QEC only works if the decoder keeps up with the quantum hardware. 100 1
