The single-qubit gates on the “o”- or “n”-qubit require one pair of clock or Raman transitions mediated by different states (Fig. 2a, b). For the “o”-sector rotations, we assume that both transitions have the same resonance frequency. This is a good approximation in a small magn...
First, perturbation theory offers an efficient way to compute sensitivities to nuclear parameters in continuous energy transport simulations: making use of the Iterated Fission Probability method, and by coupling the Monte Carlo code TRIPOLI-4® to the nuclear evaluation code CONRAD, we were able ...
What is an atom that has a different number of neutrons than other atoms of the same element? What two regions make up all atoms? Which subatomic particle identifies isotopes? If an atom with a mass number of 202 has 122 neutrons, it is an atom of which element? What is the mass of...
The matrix is dark blue with double-layered rings of “eye sockets” of different shapes randomly distributed over its surface. Each eye socket consists of two irregularly shaped white concentric rings. Some eye sockets are distorted due to compression, whereas others remain partially open. The “...
We demonstrate measurement of uranium isotopes in femtosecond laser ablation plumes using two-dimensional fluorescence spectroscopy (2DFS). The high-resolution, tunable CW-laser spectroscopy technique clearly distinguishes atomic absorption from 235U and 238U in natural and highly enriched uranium metal sampl...

of photons, single photons and single atoms, or different nuclei in the solid state, have also been produced6,7,8,9,10,11,12. Here we use a deterministic quantum logic gate to generate a ‘hybrid’ entangled state of two trapped-ion qubits held in different isotopes of calcium, perform ...
