Rabi oscillations, Ramsey fringes and spin echoes in an electrical circuit

Abstract

We present a superconducting tunnel junction circuit which behaves as a controllable atom, and whose ground and first excited state form an effective spin 1/2. By applying microwave pulses, we have performed on this circuit experiments demonstrating the controlled manipulation of the spin : Rabi precession, Ramsey interferences, and spin echoes.

To be published in the proceedings of the conference "Quantum Interferometry IV" (Trieste, March 2002) in a special issue of Fortschritte der Physik
