Geometry of Generalized Coherent States : Some Calculations of Chern Characters
Kazuyuki Fujii
This is a continuation of the preceding paper (hep-ph/0108219). First of all we make a brief review of generalized coherent states based on Lie algebra su(1,1) and prove that the r…
Geometry of Coherent States : Some Examples of Calculations of Chern-Characters
Kazuyuki Fujii
First we make a brief review of coherent states and prove that the resolution of unity can be obtained by the 1-st Chern character of some bundle. Next we define a Grassmann manifo…
Generalized Bell States and Quantum Teleportation
Kazuyuki Fujii
We make a brief comment on measurement of quantum operators with degenerate eigenstates and apply to quantum teleportation. We also try extending the quantum teleportation by Benne…
A Relation between Coherent States and Generalized Bell States
Kazuyuki Fujii
In the first half we show an interesting relation between coherent states and the Bell states in the case of spin 1/2, which was suggested by Fivel. In the latter half we treat gen…
Mathematical Foundations of Holonomic Quantum Computer II
Kazuyuki Fujii
This is a sequel to the papers (quant-ph/9910063) and (quant-ph/0004102). The aim of this paper is to give mathematical foundations to Holonomic Quantum Computation (Computer) prop…
A Lecture on Quantum Logic Gates
Kazuyuki Fujii
In this note we make a short review of constructions of n-repeated controlled unitary gates in quantum logic gates.
