Quantum Information and Quantum Optics with Superconducting Circuits - Exercise Solutions (Chapter 4)
4.1 For the thermal state : For the pure state : 4.2 By mathematical induction, you can prove: Hence: 4.4 Current conservation: Branch currents: Hence: Without the register: With the register: 4.5 4.6 This is very rough apporximation. I'm not sure if this is really an intended answer. 4.7 In the te…
