Abstract:
Efficient overlap estimation of high-dimensional quantum states is an important task in quantum information and a core element in computational speedups of quantum machine learning. Here we experimentally demonstrate the SWAP test that measures the overlap of two motional states in a system of trapped 171Yb+ ions. Our hardware efficient SWAP test circuit can be implemented with constant gate time and without a priori knowledge of various target quantum state.

Abstract:
The secretion of gonadotropin-releasing hormone (GnRH) regulates the reproductive endocrine system. The GnRH immunocontraception vaccine has been recognized as a potential tool for animal population control and management. We aimed to evaluate a recombinant GnRH fusion protein with MONTANIDE™ ISA 206 VG adjuvant as GnRH vaccine in adult ICR male mice based on anti-GnRH antibodies, concentrations of the sexual hormone, size and histomorphology of testis, semen quality. After intramuscular administration of vaccine to mice in weeks 0, 4, and 8, the response was assessed and observed that the inducing of the specific immune response at week 5 and maintain the specific antibody for at least weeks 24. Furthermore, our vaccine suc-cussed reducing the concentration of follicle-stimulating hormone (FSH), luteinizing hormone (LH), and testosterone in serum. In addition, we observed that the atrophy of testis and decreased quality of sperm in concentration, sperm morphology, and viability in the vaccine group. Through the fertility test, we found that this vaccine decreases the mating and pregnancy rate. The vaccine in this study could be used as a tool for population management of free-living animals. However, future studies that evaluation the effect of the vaccine in specific species and in the field are needed.
