Abstract
Described herein is a simulation of an input quantum circuit, comprising a machine-readable specification of a quantum circuit. Aspects include partitioning the input quantum circuit into a group of sub-circuits based on at least two groups of qubits identified for tensor slicing, wherein the resulting sub-circuits have associated sets of qubits to be used for tensor slicing. The simulating can occur in stages, one stage per sub-circuit. A set of qubits associated with a sub-circuit can be used to partition the simulated quantum state tensor for the input quantum state circuit into quantum state tensor slices, and the quantum gates in that sub-circuit can used to update the quantum state tensor slices into updated quantum state tensor slices. The updated quantum state tensor slices are stored to secondary storage as micro slices.
