Quantum simulation of the spin-boson model with a microwave circuit

Understand

We consider superconducting circuits for the purpose of simulating the spin-boson model.

• The spin-boson model consists of a single two-level system coupled to bosonic modes.
• In most cases, the model is considered in a limit where the bosonic modes are sufficiently dense to form a continuous spectral bath.
• A very well known case is the ohmic bath, where the density of states grows linearly with the frequency.
