Probing Decoherence with Electromagnetically Induced Transparency in Superconductive Quantum Circuits
K. V. R. M. Murali, D. S. Crankshaw, T. P. Orlando +2
Superconductive quantum circuits (SQCs) comprise quantized energy levels that may be coupled via microwave electromagnetic fields. Described in this way, one may draw a close analo…
DC measurements of macroscopic quantum levels in a superconducting qubit structure with a time-ordered meter
D. S. Crankshaw, K. Segall, D. Nakada +7
DC measurements are made in a superconducting, persistent current qubit structure with a time-ordered meter. The persistent-current qubit has a double-well potential, with the two…
Energy Relaxation Time between Macroscopic Quantum Levels in a Superconducting Persistent Current Qubit
Yang Yu, D. Nakada, Janice C. Lee +5
We measured the intrawell energy relaxation time τ_{d} between macroscopic quantum levels in the double well potential of a Nb persistent-current qubit. Interwell population transi…
Impact of time-ordered measurements of the two states in a niobium superconducting qubit structure
K. Segall, D. Crankshaw, D. Nakada +7
Measurements of thermal activation are made in a superconducting, niobium Persistent-Current (PC) qubit structure, which has two stable classical states of equal and opposite circu…
