In For A Penny [v0.37] -

: A new default.tensor device was added to simulate "wide" quantum circuits that have a large number of qubits. It supports both Tensor Network (TN) and Matrix Product State (MPS) simulations using the quimb backend.

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

“Suzuki-Trotter product formula allows for the ability to express higher-order approximations to the matrix exponential of a Hamiltonian.” PennyLane.ai PennyLane v0.37 and Catalyst v0.7 released “Suzuki-Trotter product formula allows for the ability to

: Users can now add noise models directly to their quantum circuits, allowing for more realistic simulations of hardware-level errors.
