    "abstract": "A quantum processor is a device with a data register and a program register.\nThe input to the program register determines the operation, which is a\ncompletely positive linear map, that will be performed on the state in the data\nregister. We develop a mathematical description for these devices, and apply it\nto several different examples of processors. The problem of finding a processor\nthat will be able to implement a given set of mappings is also examined, and it\nis shown that while it is possible to design a finite processor to realize the\nphase-damping channel, it is not possible to do so for the amplitude-damping\nchannel.",
