ChangeLog

Suzuki-Trotter-Evolver Change Log

Release 1.1.2

• Fixed bug where version checks would fail to accept Eigen version 3.4

Release 1.1.1

• Expanded support for Eigen versions to >=3.4 and <6
• Changed sparse matrices to row major to enable parallelization sparse–dense matrix products
• Fixed typo in the documentation

Release 1.1.0

• Added UnitaryEvolver::get_evolution() to generate the unitary describing the system’s evolution.

• Added unitary_gate_infidelity() to calculate gate infidelities.

• Added UnitaryEvolver::evolved_gate_infidelity() to calculate the gate infidelity of a unitary generated by a system Hamiltonian.

• Added UnitaryEvolver::gate_switching_function() to calculate the switching function with respect to the gate infidelity.

• Added UnitaryEvolver::evolved_inner_product() to calculate the inner product of an evolved state vector with some fixed vector.

• Added UnitaryEvolver::evolved_inner_product_all() to calculate the inner products of a state vector at each timestep during its evolution with some fixed vector.

• Updated the arXiv reference to:
