Quantum electromechanics: Quantum tunneling near resonance and qubits from buckling nanobars
Sergey Savel'ev, Xuedong Hu, A. Kasumov +1
Analyzing recent experimental results, we find similar behaviors and a deep analogy between three-junction superconducting qubits and suspended carbon nanotubes. When these differe…
Alteration of superconductivity of suspended carbon nanotubes by deposition of organic molecules
M. Ferrier, A. Yu. Kasumov, V. Agache +9
We have altered the superconductivity of a suspended rope of single walled carbon nanotubes, by coating it with organic polymers. Upon coating, the normal state resistance of the r…
Proximity Effect in a Superconductor-Metallofullerene-Superconductor Molecular Junction
A. Yu. Kasumov, K. Tsukagoshi, M. Kawamura +12
We report low-temperature transport measurements through molecules of Gd metallofullerenes between superconducting suspended electrodes. The presence and number of molecules in the…
Quantum transport through carbon nanotubes: proximity induced and intrinsic superconductivity
A. Kasumov, M. Kociak, M. Ferrier +6
We report low temperature transport measurements on suspended single walled carbon nanotubes (both individual tubes and ropes). The technique we have developed, where tubes are sol…
