A simplified and improved approach to tensor network operators in two dimensions
Matthew J. O'Rourke, Garnet Kin-Lic Chan
Matrix product states (MPS) and matrix product operators (MPOs) are one dimensional tensor networks that underlie the modern density matrix renormalization group (DMRG) algorithm.…
On the generalization of the exponential basis for tensor network representations of long-range interactions in two and three dimensions
Zhendong Li, Matthew J. O'Rourke, Garnet Kin-Lic Chan
In one dimension (1D), a general decaying long-range interaction can be fit to a sum of exponential interactions with varying exponents , each of which can be rep…
Conversion of projected entangled pair states into a canonical form
R. Haghshenas, Matthew J. O'Rourke, Garnet Kin-Lic Chan
We propose an algorithm to convert a projected entangled pair state (PEPS) into a canonical form, analogous to the well-known canonical form of a matrix product state. Our approach…
Hypermetallic Polar Molecules for Precision Measurements
Matthew J. O'Rourke, Nicholas R. Hutzler
Laser cooling is a powerful method to control molecules for applications in precision measurement, as well as quantum information, many-body physics, and fundamental chemistry. How…
Determining eigenstates and thermal states on a quantum computer using quantum imaginary time evolution
Mario Motta, Chong Sun, Adrian Teck Keng Tan +5
The accurate computation of Hamiltonian ground, excited, and thermal states on quantum computers stands to impact many problems in the physical and computer sciences, from quantum…
