The measurement of parameters that describe kinetic processes is important in the study molecular interactions. It enables a deeper understanding physical mechanisms underlying how different biological entities interact with each other, such as viruses cells, vaccines antibodies, or new drugs specific diseases. In this work, we theoretically use quantum sensing techniques for measuring sensor c...

One of the central tasks in quantum error-correction is to construct quantum codes that have good parameters. In this paper, we construct three new classes of quantum MDS codes from classical Hermitian self-orthogonal generalized Reed-Solomon codes. We also present some classes of quantum codes from matrix-product codes. It turns out that many of our quantum codes are new in the sense that the ...

Two types of room-temperature detectors of terahertz laser radiation have been developed which allow, in an all-electric manner, the determination of the plane of polarization of linearly polarized radiation and the Stokes parameters of elliptically polarized radiation, respectively. The operation of the detectors is based on photogalvanic effects in semiconductor quantum well structures of low...

A recent theory is reviewed for the sample-to-sample fluctuations in the critical current of a Josephson junction consisting of a disordered point contact or microbridge. The theory is based on a relation between the supercurrent and the scattering matrix in the normal state. The root-mean-square amplitude rms Ic of the critical current Ic at zero temperature is given by rms Ic ≃ e∆0/h̄, up to a...
