Influence of the external pressure on the quantum correlations of molecular magnets
C. Cruz, Á. S. Alves, R. N. dos Santos +4
The study of quantum correlations in solid state systems is a large avenue for research and their detection and manipulation are an actual challenge to overcome. In this context, w…
The IBM Quantum Computer and the IBM Quantum Experience
Alan C. Santos
The announcement of a quantum computer that can be accessed remotely by anyone from its laptop is a big event for the quantum computation scientist. In this work we present the Int…
Eigenstate Tracking in Open Quantum Systems
Jun Jing, Marcelo S. Sarandy, Daniel A. Lidar +2
Keeping a quantum system in a given instantaneous eigenstate is a control problem with numerous applications, e.g., in quantum information processing. The problem is even more chal…
Detecting entanglement of continuous variables with three mutually unbiased bases
E. C. Paul, D. S. Tasca, Lukasz Rudnicki +1
An uncertainty relation is introduced for a symmetric arrangement of three mutually unbiased bases in continuous variable phase space, and then used to derive a bipartite entanglem…
Energetic cost of superadiabatic quantum computation
Ivan B. Coulamy, Alan C. Santos, Itay Hen +1
We discuss the energetic cost of superadiabatic models of quantum computation. Specifically, we investigate the energy-time complementarity in general transitionless controlled evo…
Driver Hamiltonians for constrained optimization in quantum annealing
Itay Hen, Marcelo S. Sarandy
One of the current major challenges surrounding the use of quantum annealers for solving practical optimization problems is their inability to encode even moderately sized problems…
