Perfect Two-Photon State Transfer in a Trimer of Three-Level Systems using Laser Pulses

Abstract

We investigate two-photon transfer in a trimer of coupled three-level systems excited by laser pulses. We show that perfect state transfer and maximal entanglement are possible for certain detunings on the central site.

We investigate single and double excitation transfer in a trimer of dipole-coupled three-level systems using a Gaussian laser pulse. We demonstrate near-perfect state transfer of a double excitation to the third three-level system.

Double-excitation transfer in dimer and trimer three-level systems using laser pulses and single photons

Abuenameh Aiyejina, Ethan Wyke, Roger Andrews +1 more

We derive and simulate the wavefunctions and double-excitation probabilities for dimer and trimer three-level systems. Perfect state transfer occurs for pulse strengths that are odd multiples of π /2 when the parameter Jt equals odd multiples of π /2 and π /2 for the dimer and trimer, respectively. Near-perfect state transfer with a single photon occurred for photon coupling strength g =2 J when Jt=1.99,19.87 in the dimer and Jt=2.62,25.51 in the trimer. The nature of perfect state transfer is due to localization and transfer of double excitations for given pulse strengths and times.

Transfer efficiency in a pulsed light-harvesting trimer system

Ethan Wyke, Abuenameh Aiyejina, Roger Andrews +1 more

In this paper, the theory of the transfer efficiency of a light-harvesting system consisting of a trimer ring coupled to an acceptor site is presented. When the ring has a prepared excitation or is excited using a laser pulse, the maximum transfer efficiency is approximately 0.5, while a near-perfect transfer efficiency is generated by a single photon. The near-perfect efficiency results from the creation of a dark state by the photon, which suppresses the effect of spontaneous decay from the donor.

Transfer Efficiency in a Light-Harvesting Trimer System Using a Pair of Time-Delayed Laser Pulses

Ethan Wyke, Abuenameh Aiyejina, Roger Andrews +1 more

We analytically derive the wavefunction for a light-harvesting trimer system excited by time-delayed laser pulses. We find suppression and enhancement of the transfer efficiency depending on the time delay between the pair of laser pulses.

Generation of Entanglement in a System of Two Dipole-Interacting Atoms by Means of Laser Pulses

Igor Bargatin, B.A. Grishanin, V.N. Zadkov

Effectiveness of using laser field to produce entanglement between two dipole-interacting identical two-level atoms is considered in detail. The entanglement is achieved by driving the system with a carefully designed laser pulse transferring the system's population to one of the maximally entangled Dicke states in a way analogous to population inversion by a resonant π-pulse in a two-level atom. It is shown that for the optimally chosen pulse frequency, power and duration, the fidelity of generating a maximally entangled state approaches unity as the distance between the atoms goes to zero.
