General rules for design

• Design for interface.
• Make it most insensitive to human-error
• Keep scalability in mind
• Make it modular
• Make it easy for scripting
• Make it easy to extend
• Obey SOLID principle as much as possible
  • Single responsibility principle
  • Open-closed principle: open for extension, close for modification
  • Liskov substitution principle
  • Interface segregation principle
  • Dependency inversion principle
• Obey PEP8
• Make a good documentation

krissq_QM: kriss quantum Quantum Machine package

Conventions for setting up config

• For qubit elements, use q0, q1, q2, ...
• For resonator elements, use r0, r1, r2, ...
• For CR elements, use cr01, where 0 is the index of control qubit, and 1 is the index of target qubit.

How qm configuration is generated:

• qm_config_params.json is used to build qm_config dictionary, which is passed to the open_qm function. One needs to modify qm_config_params.json only.
• qm_config_params.json file is stored in the designated config folder, which is defined in configuration.py.

File handling

• FileHandler class takes care of saving experimental parameters, qm_config_params, qm_config, data, and figure.
• The class is currently defined in configuration.py.

Modules:`

• configuration : FileHandler, build_qm_config(), ...
• instrument: Collection of instrument drivers
• plotter
• utility:load_data, plotting, ...
• analysis
