Abstract (in Japanese) (See Japanese page) 
(in English) Tomography of a general d-dimensional quantum process is vitally important for quantum information processing and quantum control. Here we take advantages of the correlation between two weak measurements pointers to present a quantum process tomography scheme, which is characterized by its directness that each single parameter of the quantum process is determined with only one input state and two successive weak measurements. Such directness makes our scheme efficient for partial tomography and robust against error accumulation. Additionally, we just need d mutually orthogonal single-body states as the input. Our scheme can also be implemented with strong measurements without losing the advantages on directness and the simplicity of state preparation.
