摘要： A random number generator according to one embodiment includes a write circuit, a read circuit, and a signal output circuit. The write circuit inverts magnetization of a magnetic layer of a magnetic tunnel junction element stochastically by supplying current to the magnetic layer. The read circuit reads the magnetization. The signal output circuit generates a random number on the basis of the magnetization read by the read circuit. The random number generator includes a sequence control circuit that controls the write circuit and the read circuit. The sequence control circuit regulates the write circuit to supply the current to the write circuit in a first period, and causes the read circuit to read the magnetization after the first period is finished and then a second period longer than the first period is elapsed.

摘要： An information processing apparatus according to an embodiment includes a processing circuit. The processing circuit acquires a measurement field corresponding to a spatial distribution of a predetermined physical quantity in a subject of measurement. The processing circuit calculates an unknown quantity in the subject of measurement based on a first equation between the measurement field and the unknown quantity having spatial dependence, and on the acquired measurement field. The first equation is one that is acquired based on a second equation expressing a dual field divergence of which can be expressed using the measurement field, by using the measurement field and the unknown quantity, and on the Helmholtz decomposition of the dual field.

摘要： According to one embodiment, a cell identification system includes an imaging device and an identification device. The imaging device includes a well plate, a rotation mechanism, and an imaging part. The well plate is provided with a plurality of wells capable of accommodating cells. The rotation mechanism rotates the cells. The imaging part images the cells. The identification device includes processing circuitry. The processing circuitry controls the rotation mechanism to rotate the cells, controls the imaging part to image the cells each time the cells are rotated by the rotation mechanism, and inputs an image for the cells captured by the imaging part to a learned model so as to identify a cell in a good state from among the cells.
