The importance of an accurate target wave function in variational calculations for (e^{+}-H_{2}) scattering

J. N. Cooper, E. A. G. Armour, M. Plummer

Using the complex Kohn method, we have calculated variational values of phase shifts and the annihilation parameter, Z_{eff}, for the elastic scattering of positrons by molecular h…

A perturbative approach to inelastic collisions in a Bose-Einstein Condensate

R. B. Mann, M. B. Young, I. Fuentes-Schuller

It has recently been discovered that for certain rates of mode-exchange collisions analytic solutions can be found for a Hamiltonian describing the two-mode Bose-Einstein condensat…

Optimal estimation of losses at the ultimate quantum limit with non-Gaussian states

G. Adesso, F. Dell'Anno, S. De Siena +2

We address the estimation of the loss parameter of a bosonic channel probed by arbitrary signals. Unlike the optimal Gaussian probes, which can attain the ultimate bound on precisi…

Dynamical programming of continuously observed quantum systems

Viacheslav P. Belavkin, Antonio Negretti, Klaus Molmer

We develop dynamical programming methods for the purpose of optimal control of quantum states with convex constraints and concave cost and bequest functions of the quantum state. W…

Probing the quantum coherence of a nanomechanical resonator using a superconducting qubit: I. Echo scheme

A. D. Armour, M. P. Blencowe

We propose a scheme in which the quantum coherence of a nanomechanical resonator can be probed using a superconducting qubit. We consider a mechanical resonator coupled capacitivel…

Probing the quantum coherence of a nanomechanical resonator using a superconducting qubit II: Implementation

M. P. Blencowe, A. D. Armour

We describe a possible implementation of the nanomechanical quantum superposition generation and detection scheme described in the preceding, companion paper [Armour A D and Blenco…
