Free spin quantum computation with semiconductor nanostructures
Wei-Min Zhang, Yin-Zhong Wu, Chopin Soo
Taking the excess electron spin in a unit cell of semiconductor multiple quantum-dot structure as a qubit, we can implement scalable quantum computation without resorting to spin-s…
Universal quantum computation with electron spins in quantum dots based on superpositions of spacetime paths and Coulomb blockade
Cyrus C. Y. Lin, Chopin Soo, Yin-Zhong Wu +1
Using electrostatic gates to control the electron positions, we present a new controlled-NOT gate based on quantum dots. The qubit states are chosen to be the spin states of an exc…
Quantum Heisenberg Antiferromagnets versus Nonlinear Model Without the Large S Limit
Wei-Min Zhang
In this letter, I develop a new topologically invariant coherent state path integral for spin systems, and apply it to the quantum Heisenberg model on a square lattice. As a result…
Underlying Pairing States of High Superconductivity
Wei-Min Zhang
I present a microscopic theory I proposed recently to describe high-T_c superconductivity in cuprates. I show that coherent pairing states consisting of extended singlet Cooper pai…
Coherent States in Field Theory
Wei-Min Zhang
Coherent states have three main properties: coherence, overcompleteness and intrinsic geometrization. These unique properties play fundamental roles in field theory, especially, in…
Light-Front QCD and Heavy Quark Systems
Wei-Min Zhang
In this series of lectures, I shall begin with the current investigations on phenomenology of hadron dynamics to demonstrate the importance of solving hadronic bound states within…
