Abstract: Techniques and a system for visualization or interaction with a quantum processor are provided. In one example, a system includes a quantum programming component and a visualization component. The quantum programming component manages a quantum programming process to generate topology data for a quantum processor that is indicative of a physical topology of a set of qubits associated with the quantum processor. The visualization component generates visualization data for the topology data that comprises a set of planar slice elements arranged to correspond to the physical topology of the set of qubits. The set of planar slice elements indicate one or more operations performed at a time step associated with the quantum programming process.

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.
