QuantumCollocation v0.10.0

Diff since v0.9.0

Breaking changes

• update_global_params!() now raises an error for function-based QuantumSystem instances (from PiccoloQuantumObjects.jl update)

New Features

• Global parameter optimization support via updated PiccoloQuantumObjects.jl dependency - optimize system-level parameters (detunings, couplings, etc.) alongside control pulses
• SmoothPulseProblem and SplinePulseProblem automatically handle global parameters from QuantumSystem

Improvements

• Enhanced QuantumSystem compatibility with global parameter storage and optimization workflows
• Seamless integration between quantum trajectories and optimized global parameters via extract_globals() and update_global_params!()

Documentation

• Updated examples to demonstrate global parameter optimization patterns

QuantumCollocation v0.9.0

Diff since v0.8.2

changes

• instances of named trajectories .T field renamed to appropriate .N
• instances of default controls, or variables/coefficients referencing default controls changed from :a to :u (e.g. R_u, R_du, R_ddu), u_bounds, etc.)

breaking changes

For problem templates:

• a_bound, and a_bounds parameters across all problem templates have been removed (now supposed to be provided in drive_bounds for QuantumSystem struct)
• a_guess has been renamed to u_guess
• da_bound has been renamed to du_bound
• da_boundshas been renamed todu_bounds`
• dda_bound has been renamed to ddu_bound
• dda_bounds has been renamed to ddu_bounds
• R_a has been renamed to R_u
• R_da has been renamed to R_du
• R_dda has been renamed to R_ddu
• control_name default internal control variable symbol has been changed from :a to :u
• T param has been renamed to N

For quantum systems:

• params field internal to quantum systems constructed by transmons.jl, and cats.jl have been removed
• get_cat_controls function now should be user defined instead of provided by our library

For trajectory initialization (trajectory_initialization.jl)

• a_guess has been renamed to u_guess
• control_name default internal control variable symbol has been changed from :a to :u
• T param has been renamed to N
