Quantum simulations with cold trapped ions
... is, flipping either one of the two spins results in a change of energy. The physical reason is that the energy of a given spin (z) , but also on depends not only on the imposed local field B1,2 the field generated by the second spin at the location of the first one, which in turn depends on its orie ...

Computing prime factors with a Josephson phase qubit quantum
... this algorithm involves the challenge of combining both single- and coupled-qubit gates in a meaningful sequence. We constructed the full factoring sequence by first performing automatic calibration of the individual gates and then combined them, without additional tuning, so as to factor the compos ...

Phase control of trapped ion quantum gates
... each ion i and separated by energy E ↑ − E ↓ = h̄ω0 . At certain values of B0 , this energy splitting can be insensitive to magnetic field fluctuations to first order, forming a qubit that can have particularly good phase stability. Such qubit levels are termed ‘clock states’ because their stability ...

Yet, the analysis of non relativistic quantum mechanical problems can be done adequately in terms of the Jost functions, and the Jost solutions of the Schrödinger equation. The Jost function was introduc ...

Physics 30 - Structured Independent Learning
... Richter – almost simultaneously discovered a new hadron, called J by one and (psi) by the other. The J / meson was three times more massive than the proton and, remarkably, lived for 10-20 s before decaying – 1000 times longer than is normal for a hadron of that mass. The quark theory as it stoo ...
