RESUMO
Nonpairwise multiqubit interactions present a useful resource for quantum information processors. Their implementation would facilitate more efficient quantum simulations of molecules and combinatorial optimization problems, and they could simplify error suppression and error correction schemes. Here, we present a superconducting circuit architecture in which a coupling module mediates two-local and three-local interactions between three flux qubits by design. The system Hamiltonian is estimated via multiqubit pulse sequences that implement Ramsey-type interferometry between all neighboring excitation manifolds in the system. The three-local interaction is coherently tunable over several MHz via the coupler flux biases and can be turned off, which is important for applications in quantum annealing, analog quantum simulation, and gate-model quantum computation.

BACKGROUND: Cancer prevention and the early detection can affect morbidity and mortality. Through educational programs, recommendations for beneficial lifestyle changes and cancer screening may be introduced to the public. The purpose of this study was to determine whether a videotaped lecture concerning cancer prevention and early detection is of educational value. METHOD: College students in a health science class participated in the study. The students' comprehension of the subject matter was assessed immediately before and a week after they viewed the lecture. RESULT: The students' scores on the second test were significantly better as measured by a paired-difference experiment. CONCLUSION: This videotaped lecture has merit as an educational program.
