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…
Wigner rotations, Bell states, and Lorentz invariance of entanglement and von Neumann entropy
Chopin Soo, Cyrus C. Y. Lin
We compute, for massive particles, the explicit Wigner rotations of one-particle states for arbitrary Lorentz transformations; and the explicit Hermitian generators of the infinite…
A note on 4-dimensional traversable wormholes and energy conditions in higher dimensions
W. F. Kao, Chopin Soo
We show explicitly that traversable wormholes requiring exotic matter in 4-dimensions nevertheless have acceptable stress-tensors obeying reasonable energy conditions in higher dim…
Massive torsion modes from Adler-Bell-Jackiw and scaling anomalies
Lay Nam Chang, Chopin Soo
Regularization of quantum field theories introduces a mass scale which breaks axial rotational and scaling invariances. We demonstrate from first principles that axial torsion and…
The Weyl Theory of Fundamental Interactions: Is CPT violated?
Chopin Soo, Lay Nam Chang
We compare the conventional description of the interaction of matter with the four known forces in the standard model with an alternative Weyl description in which the chiral coupl…
