A Unified Framework for Operator Backpropagation and Observable Measurement in Quantum Computing
Kevin Dougherty, Ji Liu
Decoherence imposes severe limits on quantum circuit depth, motivating methods to reduce circuit depth. Operator backpropagation has recently been proposed as a way to lower circui…
Distributed Variational Quantum Linear Solver
Tong Shen, Zeru Zhu, Ji Liu
This paper develops a distributed variational quantum algorithm for solving large-scale linear equations. For a linear system of the form , the large square matrix is par…
State Dependent Optimization with Quantum Circuit Cutting
Xinpeng Li, Ji Liu, Jeffrey M. Larson +4
Quantum circuits can be reduced through optimization to better fit the constraints of quantum hardware. One such method, initial-state dependent optimization (ISDO), reduces gate c…
Hardware-Software Co-design for Distributed Quantum Computing
Ji Liu, Allen Zang, Martin Suchara +2
Distributed quantum computing (DQC) offers a pathway for scaling up quantum computing architectures beyond the confines of a single chip. Entanglement is a crucial resource for imp…
