We present measurements of coherence and successive decay dynamics of higher energy levels of a superconducting transmon qubit. By applying consecutive π pulses for each sequential transition frequency, we excite the qubit from the ground state up to its fourth excited level and characterize the decay and coherence of each state. We find the decay to(More)
Nuclear Magnetic Resonance serves as an important technique in many fields, including medicine (where it is known as MRI), chemical spectroscopy, and even quantum computation research. At its most basic, NMR is about the coherent manipulation and observation of nuclear dipole moments. Our work here deals exclusively with the hydrogen nucleus, which, being(More)
