Controlling Coherence Transfer of Dimer Interacting with Independent Environments

Abstract

We study the coherence transfer between two pigments (donor and acceptor) of a dimer interacting with two independent environments. By means of a prior weak measurement on the donor and a post measurement, which is either a reversal measurement or a weak measurement, on the acceptor, we present a scheme to optimally control the transfer of the donor's coherence to the acceptor. We construct explicit relationships for the two measurement strengths and the evolution time, by which the coherence degree of the acceptor can approach the maximum value 0.5 at the cost of a decreased probability.

On-demand control of coherence transfer between interacting qubits surrounded by a dissipative environment

Zhong‐Xiao Man, Yun‐Jie Xia, Nguyen Ba An

On-demand measurement-based schemes to control coherence transfer between interacting qubits inside a dissipative environment are considered. The measurements employed are of the types of quantum weak measurement and quantum reversal measurement of which one is carried out at the beginning of the system evolution $t=0$ and the other at a later intended time $t>0.$ The relevant questions are which type of measurement should be performed at $t=0$ and which type at $t>0$, as well as which strength of the second measurement should be chosen in dependence on the strength of the first measurement to optimally achieve a demand? We answer such questions in this work as to meet two concrete demands, namely, to make optimal (i) the transfer of coherence from the $s$th qubit to the $r$th qubit and (ii) the preservation of coherence at the $s$th qubit. Particularly, independent of the coherence degree of the $s$th qubit at $t=0,$ the coherence degree of either the $r$th qubit or the $s$th qubit at any $t>0$ can be made arbitrarily close to the maximum value equal to 1/2, but at the cost of vanishingly reduced success probability. As an application, we discuss the coherence transfer between two qubits of a bipartite system. We also analyze the influence of the controlling schemes for optimal coherence transfer on the degree of entanglement created at $t>0$ between the two qubits.

Control excitation and coherent transfer in a dimer

Hongrong Li, Pei Zhang, Yingjun Liu +2 more

In this article, the processes of energy absorption and coherent transfer in a dimer are studied. The dimer includes two two-level pigments, donor and acceptor, where the donor is assumed to be excited by a control pulse in the time domain. We investigate the dynamics of probability that the acceptor is in the excited state and the total efficiency of energy absorption and transfer under different temporal shapes of the control pulse. Quantum concurrence of the dimer is also discussed.

Protecting quantum coherence and discord from decoherence of depolarizing noise via weak measurement and measurement reversal

Abdul Basit, Fazal Badshah, Hamad Ali +1 more

Protection of the quantum coherence and discord in realistic quantum systems interacting with the environment of depolarizing noise is an important subject in quantum information processing. Weak measurement and measurement reversal can effectively suppress the amplitude damping-class decoherence. In this paper, we examine the effect of this protocol in the protection of quantum coherence and discord subjected to depolarizing noise environments. Our scheme consists of a prior weak measurement on each qubit before interacting with noisy channels followed by post measurement reversal. It is found that quantum coherence and discord can be enhanced to an optimal value by performing weak measurements and adjusting measurement parameters on each qubit. In addition, the maximal value of the quantum coherence and discord is found to be independent of the initial-state parameters.

Manipulating entanglement of two qubits in a common environment by means of weak measurements and quantum measurement reversals

Zhong‐Xiao Man, Yun‐Jie Xia, Nguyen Ba An

Addressing various types of decoherence is of paramount importance for employing entanglement in quantum information processing and quantum computing. In this paper, we propose two schemes to manipulate entanglement of two qubits stored in a common environment by means of combined weak measurements and quantum measurement reversals. We derive the explicit conditions for the measurement strengths under which at any time and for any initial states the qubits' entanglement can be protected quite well with a reasonable finite success probability. Moreover, the two schemes enable us in principle to achieve the maximal entanglement or to restore the initial state (entanglement) of the qubits.

Protecting coherence by weak measurement and quantum measurement reversal

Qiong Wang, Zhi He

Abstract The dynamic behavior of the relative entropy of coherence for a two-level system is systematically investigated in different regimes. We derive the exact expressions of relative entropy quantifying coherence for an exactly solving model consisting of single qubit interacting with independent structured reservoir, show explicitly that the weak measurement (WM) and quantum measurement reversal (QMR) operation indeed help for protecting the coherence. In addition, the freezing phenomenon of the coherence can be detected by using the optimal WM and QMR operation.

Coherent Control of Energy Transport at Room Temperature in a Noisy Bath

Davinder Singh, Paul Brumer

Coherent control of energy transport in a non-equilibrium steady-state (NESS) in a reaction-center-connected donor-acceptor pair is proposed. The pigments are considered to be continuously interacting with incoherent radiation and a phonon bath while being driven by phase-controlled coherent fields. Coherent excitation of the donor-acceptor pair is shown to induce interference between excitation pathways, resulting in phase dependent modulation of the flux. As a consequence one can enhance or suppress energy transfer via interference, e.g. an optical energy switch. The persistence of such interference enables coherent control at a NESS in dissipative regime suggests an extension of the operational scope of quantum control from traditional transient domain with low dissiaption to noisy environment NESS at room temperature.
