Abstract: This disclosure describes techniques for providing diagnosis and treatment recommendations using quantum computing. For example, a quantum computing device encodes diagnosis-relevant information of a patient as one or more patient diagnosis qubits. The quantum computing device implements a first quantum search algorithm using the patient diagnosis qubits to determine a diagnosis likelihood for each condition of a plurality of conditions. The quantum computing device further encodes the diagnosis data and treatment-relevant information of the patient as one or more patient treatment qubits. The quantum computing device implements a second quantum search algorithm using the treatment-relevant information of the patient to determine one or more treatment recommendations for the patient.
