    "abstract": "Quantum information refers to the distinctive information-processing\nproperties of quantum systems, which arise when information is stored in or\nretrieved from nonorthogonal quantum states. More information is required to\nprepare an ensemble of nonorthogonal quantum states than can be recovered from\nthe ensemble by measurements. Nonorthogonal quantum states cannot be\ndistinguished reliably, cannot be copied or cloned, and do not lead to exact\npredictions for the results of measurements. These properties contrast sharply\nwith those of information stored in the microstates of a classical system.",
