A Rabi Oscillation in Four and Five Level Systems
Kazuyuki Fujii, Kyoko Higashida, Ryosuke Kato +1
In this paper we consider a general model of an atom with n energy levels interacting with n-1 external (laser) fields which is a natural extension in the two and three level syste…
Quantum Optical Construction of Generalized Pauli and Walsh-Hadamard Matrices in Three Level Systems
Kazuyuki Fujii
A set of generators of generalized Pauli matrices play a crucial role in quantum computation based on n level systems of an atom. In this paper we show how to construct them by mak…
Cavity QED and Quantum Computation in the Strong Coupling Regime II : Two Atoms Case
Kazuyuki Fujii
In this paper we study the behavior of (laser--cooled) m--atoms trapped in a cavity interacting with a photon Cavity QED and attempt to solve the Schr{ö}dinger equation…
N Level System with RWA and Analytical Solutions Revisited
Kazuyuki Fujii, Kyoko Higashida, Ryosuke Kato +1
In this paper we consider a model of an atom with n energy levels interacting with n(n-1)/2 external (laser) fields which is a natural extension of two level system, and assume the…
Cavity QED and Quantum Computation in the Strong Coupling Regime
Kazuyuki Fujii
In this paper we propose a Hamiltonian generalizing the interaction of the two--level atom and both the single radiation mode and external field a kind of cavity QED. We solv…
A Generalized Hamiltonian Characterizing the Interaction of the Two-Level Atom and both the Single Radiation Mode and External Field
Kazuyuki Fujii
In this paper we propose some Hamiltonian characterizing the interaction of the two-level atom and both the single radiation mode and external field, which might be a generalizatio…
