Within the research domain of process mining process discovery aims at constructing a process model as an abstract representation of an event log The goal is to build a model a Petri net that provides insight into the behavior captured in the log
There are many process mining algorithms and representations making it difficult to choose which algorithm to use or compare results Process mining is essentially a machine learning task but little work has been done on systematically analyzing algorithms to understand their fundamental properties such as how much data are needed for confidence in

A further challenge when preparing the data for process mining is the definition of the case ID which is necessary for process mining algorithms to extract process models from event logs The case notion might be ambiguous and thus selecting and assigning an appropriate case ID during correlation is challenging since no distinction of cases
Many academics in the field of data mining have focused on quantum computing as a solution to these problems Traditional algorithms have issues with computational efficiency but quantum computing offers a new solution [] Quantum computers use quantum bits or qubits which can exist in superposition states as opposed to classical computers which process data

Process mining algorithms utilize event logs as their input Event logs consist of a sequence of events with a name describing the observed action and its corresponding timestamp when the event occurred The temporally ordered sequence of such events is called a trace Commonly a trace contains only events that belong to the same context
