Unified scheme for correlations using linear relative entropy
M. Daoud, R. Ahl Laamara, W. Kaydi
A linearized variant of relative entropy is used to quantify in a unified scheme the different kinds of correlations in a bipartite quantum system. As illustration, we consider a t…
Pairwise quantum and classical correlations in multi-qubits states via linear relative entropy
M. Daoud, R. Ahl Laamara, H. El Hadfi
The pairwise correlations in a multi-qubit state are quantified through a linear variant of relative entropy. In particular, we derive the explicit expressions of total, quantum an…
Quantum annealing: the fastest route to quantum computation?
C. R. Laumann, R. Moessner, A. Scardicchio +1
In this review we consider the performance of the quantum adiabatic algorithm for the solution of decision problems. We divide the possible failure mechanisms into two sets: small…
Dark Bogolon-Excitons in a Linear Atomic Super-Lattice
Hashem Zoubi
Dark and bright excitons are shown to appear naturally in a linear atomic super-lattice with two atoms per unit cell. In bringing the super-lattice into a strong coupling regime wi…
Dynamically controlling the emission of single excitons in photonic crystal cavities
Francesco Pagliano, YongJin Cho, Tian Xia +3
Single excitons in semiconductor microcavities represent a solid-state and scalable platform for cavity quantum electrodynamics (c-QED), potentially enabling an interface between f…
Critical quasienergy states in driven many-body systems
Victor Manuel Bastidas, Georg Engelhardt, Pedro Perez-Fernandez +2
We discuss singularities in the spectrum of driven many-body spin systems. In contrast to undriven models, the driving allows us to control the geometry of the quasienergy landscap…
