## Abstract

Techniques for resolving qubit usage conflicts arising from different versions of a quantum file are disclosed. A first qubit having original data associated with a first version of a quantum file may be modified to store first modified data associated with a second version of the quantum file. In response to receiving a request to modify the first qubit with second modified data associated with a proposed third version of the quantum file, a set of auxiliary qubits is allocated. The original data, the first modified data and the second modified data are stored in respective auxiliary qubits and a version conflict file referencing the respective auxiliary qubits is generated. When a request to access a current version of the quantum file is received, the version conflict file is returned allowing for creation of any of the first, second or third versions of the quantum file on an ad-hoc basis.
