Properties and Backgrounds
When creating a new registers, you can specify what type of physical system it will contain in each slot, e.g. a Qubit
or a qudit or a harmonic oscillator or a propagating wave packet.
For each subsystem (slot in the register), you also specify what background processes and noise parameters describe it. For instance, it could be a T1Decay
or T2Dephasing
process, or a coherent error, or a non-Markovian bath.
