v0.8.0

PiccoloQuantumObjects v0.8.0

Diff since v0.7.5

Changes

• updated direct sum tests to validate Hermitian properties of resulting matrices.
• consolidated operator lifting logic by replacing lift_ion_op and lift_mode_op with a single lift_operator function.
• update control name default to support vector type for detuning in IonChainMSSystem

Added

• QuantumTrajectories module and reexport in PiccoloQuantumObjects
• quantum system templates and optimization constraints (to removed from QuantumCollocation.jl)
• time_dependent field to OpenQuantumSystem and QuantumSystem structs
• QuantumSystemTemplates module with templates for Transmon, MultiTransmon, Rydberg, and Cat systems.
• coherent_ket and get_cat_controls functions for Cat systems.
• leakage and fidelity constraints in QuantumConstraints module for trajectory optimization.
• integrators for various quantum systems in QuantumIntegrators module.
• objective functions in QuantumObjectives module to include infidelity and leakage objectives.
• IonChainSystem and MolmerSorensenCoupling for trapped ion simulations
• Add EnsembleTrajectory and SamplingTrajectory types for ensemble optimization
• get_initial_controls function for uniform control initialization in quantum systems

Removed

• obsolete quantum optimization modules and update trajectory accessors

Breaking changes

• Removal and refactoring of obselete quantum optimization modules and trajectory accessors
• Removal of former concrete type with new abstract type, sub-typed with ket-trajectory, unitary-trajectory, and density-trajectory
