|Superconducting Quantum Physics Group is a
research group in the NTT Basic Research Laboratories in the Division
of Physical Science Laboratory.
Our group studies quantum physics through artificially
designed superconducting circuits or ultracold neutral atoms including
Bose-Einstein condensate. The physics of macroscopic quantum phenomena
is really fascinating, and at sufficiently low temperatures, quantum
mechanical behavior (ODLRO: off-diagonal long range order) emerges
with macroscopic numbers of constituents over a scale of mm or
more, which we could never observe in the classical world. There,
a state of the electrical circuit can be described as a single
wavefunction, energy levels are quantized, just like in atoms and
molecules. Our research focuses on understanding and controlling
the quantum properties such as superconducting quantum circuits,
a microwave photon resonator, a nanomechanical resonator, and ultracold
neutral atoms in trapping potential, with possible applications
toward the quantum computation and novel electronic devices.
The permanent staff in our group are Kousuke Kakuyanagi,
Shin-ichi Karimoto, Yuichiro Matsuzaki, Hayato Nakano, Shiro Saito,
Kouichi Semba(group leader), and Hirotaka Tanaka.
