Gluon Field Digitization via Group Space Decimation for Quantum Computers
Yao Ji, Henry Lamm, Shuchen Zhu
Efficient digitization is required for quantum simulations of gauge theories. Schemes based on discrete subgroups use fewer qubits at the cost of systematic errors. We systematize…

A Theory of Trotter Error
Andrew M. Childs, Yuan Su, Minh C. Tran +2
The Lie-Trotter formula, together with its higher-order generalizations, provides a direct approach to decomposing the exponential of a sum of operators. Despite significant effort…
