Analysis of an all-to-all connected star array of transmon qubits
Ricardo A. Pinto
We analyzed quantum and coupling and state transfer in an all-to-all connected star array of capacitively coupled superconducting transmon qubits. It is shown that in a h…
Surface states in defect-free polyatomic lattices described by a tight-binding model
Ricardo A. Pinto
We report about a mechanism for surface localization, present in finite defect-free polyatomic lattices described by a tight binding model. Numerical diagonalization and degenerate…
Analysis of a tuneable coupler for superconducting phase qubits
Ricardo A. Pinto, Alexander N. Korotkov, Michael R. Geller +2
This paper presents a theoretical analysis of the recently realized tuneable coupler for superconducting phase qubits (R. C. Bialczak et al., Ref.\ \protect\onlinecite{Bialczak}).…
Quantum discrete breathers
Ricardo A. Pinto, Sergej Flach
We review recent studies about quantum discrete breathers. We describe their basic properties in comparison with their classical counterparts, and the ways they may be addressed th…
Edge-localized states in quantum one-dimensional lattices
Ricardo A. Pinto, Masudul Haque, Sergej Flach
In one-dimensional quantum lattice models with open boundaries, we find and study localization at the lattice edge. We show that edge-localized eigenstates can be found in both bos…
Boundary effects on quantum q-breathers in a Bose-Hubbard chain
Ricardo A. Pinto, Jean Pierre Nguenang, Sergej Flach
We investigate the spectrum and eigenstates of a Bose-Hubbard chain containing two bosons with fixed boundary conditions. In the noninteracting case the eigenstates of the system d…
