Gate Based Implementation of the Laplacian with BRGC Code for Universal Quantum Computers
Ermal Rrapaj, Kenneth S. McElvain, Chia Cheng Chang +2
We study the gate-based implementation of the binary reflected Gray code (BRGC) and binary code of the unitary time evolution operator due to the Laplacian discretized on a lattice…
Lossy compression of statistical data using quantum annealer
Boram Yoon, Nga T. T. Nguyen, Chia Cheng Chang +1
We present a new lossy compression algorithm for statistical floating-point data through a representation learning with binary variables. The algorithm finds a set of basis vectors…
Improving Schrödinger Equation Implementations with Gray Code for Adiabatic Quantum Computers
Chia Cheng Chang, Kenneth S. McElvain, Ermal Rrapaj +1
We reformulate the continuous space Schrödinger equation in terms of spin Hamiltonians. For the kinetic energy operator, the critical concept facilitating the reduction in model co…
Integer Programming from Quantum Annealing and Open Quantum Systems
Chia Cheng Chang, Chih-Chieh Chen, Christopher Koerber +2
While quantum computing proposes promising solutions to computational problems not accessible with classical approaches, due to current hardware constraints, most quantum algorithm…
Quantum annealing for systems of polynomial equations
Chia Cheng Chang, Arjun Gambhir, Travis S. Humble +1
Numerous scientific and engineering applications require numerically solving systems of equations. Classically solving a general set of polynomial equations requires iterative solv…
