The Dynamical Yang-Baxter Relation and the Minimal Representation of the Elliptic Quantum Group
Heng Fan, Bo-Yu Hou, Kang-Jie Shi +2
In this paper, we give the general forms of the minimal matrix (the elements of the -matrix are numbers) associated with the Boltzmann weights of the interac…
Optimal two-qubit quantum circuits using exchange interactions
Heng Fan, Vwani Roychowdhury, Thomas Szkopek
The Heisenberg exchange interaction is a natural method to implement non-local (i.e., multi-qubit) quantum gates in quantum information processing. We consider quantum circuits com…
Entanglement in a Valence-Bond-Solid State
Heng Fan, Vladimir Korepin, Vwani Roychowdhury
We study entanglement in Valence-Bond-Solid state. It describes the ground state of Affleck, Kennedy, Lieb and Tasaki quantum spin chain. The AKLT model has a gap and open boundary…
Entanglement of eta-pairing state with off-diagonal long-range order
Heng Fan, Seth Lloyd
Off-diagonal long-range order (ODLRO) is a quantum phenomenon not describable in classical mechanical terms. It is believed to be one characteristic of superconductivity. The quant…
