Infrastructure integration barrier
One of the natural barriers for companies looking to explore solutions with quantum computing is how to integrate them into their current operations. Depending on the case, the technology of real quantum hardware can be more or less prepared for real-time response and coexist with the current systems that the companies have deployed in the cloud. Particularly in the QML field, for classification challenges (credit scoring or fraud prediction), the instant response from a QC could be an issue to solve, since most of the machines have a queue system due to the small number of computers available. As a valid option, companies can use several types of simulators in the cloud to operate in a low range of qubits (most of the hybrid quantum-classical algorithms for QML operate quite well with a few tens of qubits) below the 40-qubit line.
The use of simulators can represent a good cost-efficient option, since the quantum algorithms can run faster (in...
