Suspicious behavior when decoding d=21 surface codes

This is a plot that intermingles logical error rates from pymatching and from an internal MWPM decoder. They're pretty close up to d19 or so but then things get kinda...

- Change TICK convention so that first TICK is index 1 instead of index 0 - Fix circuit timeline svg diagrams using width/height instead of viewbox property - Add stim._DiagramHelper...

This is basically what the detector error model extraction does, except I want to record where the detector went instead of only which errors it touched. This will probably require...

cirq.X**"text" half works

To my surprise, if you write `cirq.X**"text"` instead of `cirq.X**sympy.Symbol("text")`, thing mostly work. For example, you can run a sweep over the circuit with a dictionary mapping `"text"` to a...

### Describe the issue Recently I started noticing my github CI builds hanging. They were getting into an infinite loop of printing out `AddressSanitizer:DEADLYSIGNAL`. Initially I assumed this was my...

Sometimes you want to work with pauli products directly, without having to decompose them. ``` + add_gate( + failed, + Gate{ + .name = "CPP", + .id = GateType::CPP, +...

For example, this circuit diagram should somehow show qubit 0 moving from one place to another. ``` QUBIT_COORDS(80, 90) 0 H 0 TICK QUBIT_COORDS(100, 90) 0 TICK S 0 TICK...
