Quantum Seals
In this paper quantum seals will be introduced. A quantum seal is a way of encoding a classical message into quantum states, so that everybody can read the message error-free, but at the same time the sender and all intended readers who have some prior knowledge of the quantum seal, can check if the seal has been broken and the message read. The verification is done without reading nor disturbi...
متن کاملQuantum seals
A quantum seal is a way of encoding a message into quantum states, so that anybody may read the message with little error, while authorized verifiers can detect that the seal has been broken. We present a simple extension to the Bechmann-Pasquinucci majority-voting scheme that is impervious to coherent attacks, and further, encompasses sealing quantum messages by means of quantum encryption. Th...
متن کاملContraceptive effect of proligestone on spotted seals and crossbreeds of spotted seals and harbor seals.
Spotted seals (Phoca largha) and related crossbreeds maintained at Kamogawa Sea World breed seasonally from the end of January to middle of March. For contraception in these animals, the effect of a single administration of a contraceptive synthetic luteal hormone for dogs, proligestone (PRG), was investigated. The animals tested were 10 seals aged 4-24 years old, and a total of 35 trials were ...
متن کاملFlow Seals Parameters Analysis For Rotors
The interaction of work fluid mechanics with that of the rotary system itself, basically composed of axes, bearings and rotors, is performed by inserting equivalent dynamic coefficients in the mathematical model of the rotor, the latter being obtained by the finite element method. In this paper, the dynamic coefficients of inertia, stiffness and damping of the flat seals analyzed here are evalu...
متن کاملSanpodo seals precursors’ fate
Sanpodo seals precursors' fate D uring Drosophila development, sensory organ precursor (SOP) cells undergo a series of asym-metric divisions to generate mechanosen-sory bristles along the thorax of adult fl ies. Notch signaling controls the fate of the SOP cells' progeny, ensuring that each bristle contains a single neuron surrounded by hair, socket, and sheath cells. Upadhyay et al. describe h...
