default.tensor

default.tensor is PennyLane’s simple simulator for performing tensor network and matrix product state simulations of quantum circuits using the quimb backend.

Recommended for:

• State vector simulations with many qubits.
• Tensor Network (TN) & Matrix Product State (MPS) backend support.
• Differentiability via the parameter-shift rule.
• All operating systems.
