- Josephson Ring Modulator Coupler Measurement
- Adiabatic Quantum Computation aims at finding the solution for optimization problems by adiabatic Hamiltonian evolution. Physically, the problems are encoded in the so-called Ising Hamiltonian and the task is to find the state of lowest energy, the ground state. As can be seen in the Ising Hamiltonian, all spins have to interact with all other spins to be able to deal with general optimization problems. In practice, achieving this all-to-all connectivity is a hard task. A particularly promising approach is the so-called Lechner-Hauke-Zoller architecture, which we want to implement with superconducting circuits. There, one of the fundamental building block is a Josephson ring modulator coupler featuring the strong ZZ interaction. Your task will be the experimental characterization of the JRM coupler. You will analyze the ZZ interaction strength in the on-state and the parasitic cross-talk between the qubits in the off-state of the coupler. Ultimately, you will realize a simple quantum annealing protocol.
