In For A Penny [v0.37] Apr 2026

The v0.37 release introduced several major technical improvements for quantum circuit simulation:

: Users can now add noise models directly to their quantum circuits, allowing for more realistic simulations of hardware-level errors. In for a Penny [v0.37]

: Integration with Catalyst was improved to accelerate classical processing on GPUs, including just-in-time (JIT) compilation for faster workflows. The v0
