In For A Penny [v0.37] Apr 2026

: New tools for debugging quantum algorithms were included to help developers catch errors more efficiently. Perspectives on PennyLane releases

: 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]

: 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. : New tools for debugging quantum algorithms were

: Integration with Catalyst was improved to accelerate classical processing on GPUs, including just-in-time (JIT) compilation for faster workflows. It supports both Tensor Network (TN) and Matrix

“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

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

“A new tensor network and matrix product state device. Wide circuits, meet default.tensor.” PennyLane.ai · 1 year ago
