Abstract
A quantum oracle, configured to implement a discrete-variable representation (DVR) matrix, operates by: loading a first column of the DVR matrix via a quantum random access memory oracle; recursively loading an additional N−1 columns of the DVR matrix via an alternating sequence of unitary circuits operating on a first set of qubits and a second set of qubits controlled via a column index; and transferring states of the first set of qubits and the second set of qubits to a quantum register controlled by a parity of the column index.
