Sturmian bases for two-electron systems in hyperspherical coordinates
A. Abdouraman, Ana Laura Frappiccini, A. Hamido +5
We give a detailed account of an spectral approach for the calculation of energy spectra of two active electron atoms in a system of hyperspherical coordina…
Direct identification of dilute surface spins on AlO: Origin of flux noise in quantum circuits
S. E. de Graaf, A. A. Adamyan, T. Lindström +4
It is universally accepted that noise and decoherence affecting the performance of superconducting quantum circuits are consistent with the presence of spurious two-level systems (…
Generating Quantum States through Spin Chain Dynamics
Alastair Kay
Spin chains can realise perfect quantum state transfer between the two ends via judicious choice of coupling strengths. In this paper, we study what other states can be created by…
A Note on the Speed of Perfect State Transfer
Alastair Kay, Weichen Xie, Christino Tamon
In Phys. Rev. A 74, 030303 (2006), Yung showed that for a one-dimensional spin chain of length and maximum coupling strength , the time for a quantum state to t…
Tailoring Spin Chain Dynamics for Fractional Revivals
Alastair Kay
The production of quantum states required for use in quantum protocols & technologies is studied by developing the tools to re-engineer a perfect state transfer spin chain so that…
