Good time at NTT
It is more than a week I am back from NTT. It was a very good visit, both productive and informative. Here are some highlights.
With Yasuhiro Tokura, we have started collaboration on nuclear punping effects on transport in quantum dots. With Toshihiro Kubo, we have started collaboration on mesoscopic interference effects in two quantum dots. I hope very much we can bring these challenging and interesting projects to the end.
Makoto Yamashita has explained me his research in cold atoms, in particular, his studies of Bose shells. Tetsuya Mukai has shared his ideas of atom chip where several atoms are trapped above the surface of a superconductor with magnetic field of superconducting currents.
I listened to the talk of Fumiki Yoshihara from NEC Tsukuba: he presented a long-awaited experimental charactetization of flux noise in superconducting qubits. The noise seems to come from the surface. Hayato Nakano gave a detailed review of his work on “practical” measurement, theoretical research on details of collective quantum mechanics of a qubit and a detector.
Hiroshi Yamaguchi has open me new horizons in nanomechanics: he has original thoughts and plans that differ from those I accustom to. How about a computer solely based on non-linearities of nanomechanical resonators?
Many if not most discussions have been with Koji Muraki, the head of quantum dot group, his students and postdocs. I have learned about the gap at nu=2/5, was updated on charge qubits, charge measurement, exotic Kondo and, of course, on nuclear pumping effects. Here, I guess, Tokura and me were able to contribute to understanding of the experiment
