We propose two schemes for generating entanglement and quantum state transfer (QST) between two spatially separated semiconductor quantum dot molecules (QDMs) based on the voltagecontrolled tunneling effects. In the present schemes, two QDMs are trapped into two spatially separated cavities connected by a fiber, respectively. By numerically simulating the evolution of system, we show that the generation of entanglement and QST can be controlled by an external gate voltage in our schemes. Moreover, proposed schemes are robust against noise of system parameters.

“…This could be accomplished using highly sensitive micro-cavity [58,59,60,61], micro-disc [62,63,64,65,66], or fiber-based fluorescence [67,68] techniques. In this feasibility study however, we focus on simple resonant absorption imaging using external optical elements in order to avoid further fabrication on the CNT atomchip (although, if required, this can indeed be done).…”

We present a feasibility study for loading cold atomic clouds into magnetic traps created by singlewall carbon nanotubes grown directly onto dielectric surfaces. We show that atoms may be captured for experimentally sustainable nanotube currents, generating trapped clouds whose densities and lifetimes are sufficient to enable detection by simple imaging methods. This opens the way for a novel type of conductor to be used in atomchips, enabling atom trapping at sub-micron distances, with implications for both fundamental studies and for technological applications.

“…A good cavity can store photons for a long time before they got dissipated. These facts have proved cavity-QED to be a very useful platform for processing quantum information [1][2][3][4][5][6][7]. An alternative to the cavity-QED scenario is provided by its solid-state analog, termed as circuit-QED, where superconducting qubits are coupled to stripline resonators [8][9][10].…”

Dynamics of interacting Dicke model in a coupled-cavity array

We consider the dynamics of an array of mutually interacting cavities, each containing an ensemble of N two-level atoms. By exploring the possibilities offered by ensembles of various dimensions and a range of atom-light and photon-hopping values, we investigate the generation of multi-site entanglement, as well as the performance of excitation transfer across the array resulting from the competition between on-site non-linearities of the matter-light interaction and inter-site photon hopping. In particular, for a three cavities interacting system it is observed that the initial excitation in the first cavity completely transfers to the ensemble in the third cavity through the hopping of photons between the adjacent cavities. Probabilities of the transfer of excitation of the cavity modes and ensembles exhibit characteristics of fast and slow oscillations governed by coupling and hopping parameters respectively. In the large hopping case, by seeding an initial excitation in the cavity at the center of the array, a tripartite W state, as well as a bipartite maximally entangled state is obtained, depending on the interaction time. Population of the ensemble in a cavity has a positive impact on the rate of excitation-transfer between the ensembles and their local cavity modes. In particular, for ensembles of 5 to 7 atoms, tripartite W states can be produced even when the hopping rate is comparable to the cavity-atom one. A similar behavior of the transfer of excitation is observed for a four coupled-cavity system with two initial excitations.
