Window shows Claude chat the uses the Stim-MCP. ###### Left side (chat): show me how the logical error changes as I use larger and larger surface codes. Mar 17 I'll build rotated surface codes for distances 3, 5, 7, and 9, inject depolarizing noise, and sample logical error rates. Let me run them one by one. Create circuit Create circuit Let me use Stim's proper surface code format with detectors and observables so we get actual logical error rates: Used stim-quantum integration Used stim-quantum integration Good, d=3 logical error rate ≈ 0.622%. Now let me use Stim's built-in surface code generator for cleaner, properly structured circuits for all distances: Used stim-quantum integration Used stim-quantum integration The X-ancilla measurement rates ~50% means the H gates are putting them into superposition before measurement without proper reset into the right basis. Let me take the cleaner approach — use the well-known Stim surface code circuit format that's guaranteed correct: ... ###### Right side (preview): *shows some output plots from later in that conversation* Surface Code Scaling — Simulation vs. Google Hardware, with Willow-matched noise Stim v1.15 · rotated_memory_z · MWPM decoding (pymatching) · 10 rounds · 200k–2M shots Google 2023: Sycamore · Nature 614, 676–681 | Google 2024: Willow · Nature Dec 2024 / arXiv:2408.13687

Taken from Fig. 4 of our paper. These plots show how advantagous the global strategy is over the local ones. The further the curve drop - the larger the advantage for the global policy. Different colours represent different local polices; different markers represent different amounts multiplexing - parallel links being created.
A schematic depicting the process of entanglement distillation
Figure from Mantri et al. 2024 http://arxiv.org/abs/2409.06152 Figure 3: Schematic of a nested swapping protocol. We start with N elementary segments each of length l0. The red boxes represent a swapping operation. Based on the decision variable Di, distillation may be performed before a swapping operation. Each swapping operation doubles the length of the link. This process is repeated until an end-to-end link is established.
