Implementation of the refined Deutsch-Jozsa algorithn on a 3-bit NMR quantum computer

open access: yes, 1999
We implemented the refined Deutsch-Jozsa algorithm on a 3-bit nuclear magnetic resonance quantum computer, which is the meaningful test of quantum parallelism because qubits are entangled. All of the balanced and constant functions were realized exactly.

The analytic value of a 3-loop sunrise graph in a particular kinematical configuration [PDF]

open access: yes, 2002
We consider the scalar integral associated to the 3-loop sunrise graph with a massless line, two massive lines of equal mass $M$, a fourth line of mass equal to $Mx$, and the external invariant timelike and equal to the square of the fourth mass.

Quantum groups, Yang-Baxter maps and quasi-determinants

open access: yes, 2017
For any quasi-triangular Hopf algebra, there exists the universal R-matrix, which satisfies the Yang-Baxter equation. It is known that the adjoint action of the universal R-matrix on the elements of the tensor square of the algebra constitutes a quantum ...

Fine‐scale reconstruction of pelagic fish migration by iso‐logging of eye lens

open access: yesMethods in Ecology and Evolution, Volume 17, Issue 1, Page 77-84, January 2026.
Abstract Understanding lifetime space use by pelagic animals is pivotal for ecology and fisheries management, but electronic tags are costly, labour‐intensive and rarely able to capture juvenile movement. We implemented an iso‐logging workflow that converts stable isotope chronologies in eye lenses into continuous migration tracks, and demonstrate its ...

Simulation of Quantum Magnetism in Mixed Spin Systems with Impurity Doped Ion Crystal

open access: yes, 2011
We propose the realization of linear crystals of cold ions which contain different atomic species for investigating quantum phase transitions and frustration effects in spin system beyond the commonly discussed case of $s=1/2$.
