Quantum Computational Method of Finding the Ground State Energy and Expectation Values
Sangchul Oh
We propose a new quantum computational way of obtaining a ground-state energy and expectation values of observables of interacting Hamiltonians. It is based on the combination of t…

Entanglement and Quantum Phase Transitions via Adiabatic Quantum Computation
Sangchul Oh
For a finite XY chain and a finite two-dimensional Ising lattice, it is shown that the paramagnetic ground state is adiabatically transformed to the GHZ state in the ferromagnetic…
