Descripción
Quantum process tomography is a useful tool for characterizing quantum processes. This task isessential for the development of different areas, such as quantum information processing. In thiswork, we present a protocol for selective continuous-variable quantum process tomography. Ourproposal allows one to selectively estimate any element of an unknown continuous-variable quantumprocess in the position representation, without requiring the complete reconstruction of the process.By resorting to controlled squeezing and translation operations, and adaptatively discretizing theprocess, a direct measure of an estimate of any process element can be obtained. Furthermore, weshow, supported by numerical simulations, how the protocol can be used to partially reconstruct ona region a continuous-variable quantum process.
