Complete characterization of quantum-optical processes

The technologies of quantum information and quantum control are rapidly improving, but full exploitation of their capabilities requires complete characterization and assessment of processes that occur within quantum devices. We present a method for characterizing, with arbitrarily high accuracy, any quantum optical process. Our protocol recovers complete knowledge of the process by studying, via homodyne tomography, its effect on a set of coherent states, that is, classical fields produced by common laser sources. We demonstrate the capability of our protocol by evaluating and experimentally verifying the effect of a test process on squeezed vacuum.  相似文献

Abstract.— The accumulation of ultraviolet (UV)‐screen substances, mycosporine‐like amino acids (MAAs), in the tetrasporophytic phase of the red alga Asparagopsis armata grown in fishpond effluents of gilthead sea bream, Sparus aurata, is analyzed. Both the effects of total ammonium nitrogen (TAN) fluxes and the algal densities on MAA accumulation were investigated. MAAs increased with the TAN flux, but only until values lower than 100 μM/h. Above this flux, the MAA content decreased, whereas algal yield increased. The content of individual MAAs was related to nitrogen (N) status, that is, shinorine percentage slightly decreased and palythine increased with increasing N fluxes. The decrease of MAAs at high flux of N (up to 100 μM/h) is related to the decrease of water residence time and the decrease of the biofiltration efficiency. Under different TAN fluxes and algal densities, MAA content was negatively related to algal yield indicating that MAAs were accumulated only under a high ammonium‐N availability. Thus, an energy allocation between growth (primary metabolism) and MAA accumulation (secondary metabolism) is regulated by the absorption capacity of inorganic N. In conclusion, A. armata, in addition to its high biofiltration capacity of nutrients, is a good source of MAAs as potential UV screen photoprotectors.  相似文献

Influence of Low Molecular Weight Glutenins on Viscoelastic Properties of Intact Wheat Kernels and Their Relation to Functional Properties of Wheat Dough

The mechanical and viscoelastic properties of intact wheat kernels of 36 wheat cultivars differing in low molecular weight glutenin subunit (LMW‐GS) composition (loci Glu‐A3, Glu‐B3, and Glu‐D3) were evaluated using load‐compression tests. Comparison among genotypic groups representing Glu‐3 allelic variants showed that groups representing the alleles Glu‐A3 b, c, and d; Glu‐B3 d, g, and h; and Glu‐D3 a, b, and d, had harder kernel texture, higher kernel elastic work and larger gluten strength‐related parameters than those possessing alleles Glu‐A3 e; Glu‐B3 f, i and j (translocation 1B/1R); and Glu‐D3 d. Modulus of elasticity (stress to strain ratio) showed low values (111.9–168.8 MPa) for allelic groups possessing poor elastic properties (Glu‐A3 e; Glu‐B3 f, i, and j; and Glu‐D3 d), and high values (179.8–222.6 MPa) for allelic groups possessing high kernel elastic properties (Glu‐A3 b c, and d; Glu‐B3 d, g, and h; and Glu‐D3 a, b and c). The highest values for gluten strength‐related parameters (SDS‐sedimentation, dough mixing time, and dough strength [W]) corresponded to allelic groups Glu‐A3 d; Glu‐B3 d and g; and Glu‐D3 d, while the lowest corresponded to Glu‐A3 e and Glu‐B3 j. No significant differences were observed among groups with regard to gluten extensibility parameters; however, the highest P/L value (least extensibility) corresponded to Glu‐B3 j, which indicates presence of 1B/1R translocation. Except for the Glu‐B3 j (translocation 1B/1R) allele, which presented more variation within samples, a general relationship between kernel viscoelastic properties and dough viscoelastic properties was observed; samples showing higher elastic work to plastic work ratio (E/P) tended to possess better gluten strength than cultivars with low E/P ratio.  相似文献
