Abstract

Recently, the evolution of wireless energy transfer can be described as Schrodinger equation. Thus, the transfer protocol of wireless energy transfer can be designed by coherent quantum control techniques, which can achieve efficient and robust energy transfer from transmitter to receiver. In this paper, we propose a novel design of wireless energy transfer which obtains the longer distance, efficient and robust schematic of power transfer, via multiple states of triangle crossing pattern. After our calculations, we demonstrate that our design can provide much longer transfer distance with relatively smaller decreasing transfer efficiency.

Wireless adiabatic power transfer

Andon A. Rangelov, Haim Suchowski, Yaron R. Silberberg +1 more

We propose a technique for efficient mid-range wireless power transfer between two coils, by adapting the process of adiabatic passage for a coherently driven two-state quantum system to the realm of wireless energy transfer. The proposed technique is shown to be robust to noise, resonant constraints, and other interferences that exist in the neighborhood of the coils.

Fast and efficient wireless power transfer via transitionless quantum driving

Koushik Paul, Amarendra K. Sarma

Shortcut to adiabaticity (STA) techniques have the potential to drive a system beyond the adiabatic limits. Here, we present a robust and efficient method for wireless power transfer (WPT) between two coils based on the so-called transitionless quantum driving (TQD) algorithm. We show that it is possible to transfer power between the coils significantly fast compared to its adiabatic counterpart. The scheme is fairly robust against the variations in the coupling strength and the coupling distance between the coils. Also, the scheme is found to be reasonably immune to intrinsic losses in the coils.

Quantum maximum power transfer theorem

Cortes, Cristian L., Zubin Jacob

We discover the quantum analog of the well-known classical maximum power transfer theorem. Our theoretical framework considers the continuous steady-state problem of coherent energy transfer through an N-node bosonic network coupled to an external dissipative load. We present an exact solution for optimal power transfer in the form of the maximum power transfer theorem known in the design of electrical circuits. We provide analytical expressions for both the maximum power delivered to the load as well as the energy transfer efficiency which are exact analogs to their classical counterparts. Our results are applicable to both ordered and disordered quantum networks with graph-like structures ranging from nearest-neighbour to all-to-all connectivities. This work points towards universal design principles which adapt ideas of power transfer from the classical domain to the quantum regime for applications in energy-harvesting, wireless power transfer, energy transduction, as well as future applications in quantum power circuit design.

Comparison of Energy Encryption Techniques for Near-Field WPT Security Application

Siti Nur Ainsyah Ghani, Latifah Mohamed, Azuwa binti Ali

This paper discusses the energy encryption techniques for wireless power transfer (WPT). The WPT system can be categorized into three groups based on power transfer distances which are near-, medium-, and far-fields. Near-field is wireless power transfer within short distance while medium-field is the wireless power transfer with range more than short distance but not more than far field distance. In the near-field, contactless techniques such as inductive coupling and capacitive coupling are employed in WPT. In the medium-field WPT, a magnetic resonant coupling approach is employed. Electromagnetic radiation is used in the far-field WPT. Energy encryption is crucial in ensuring that electricity is delivered to the intended recipient. The energy encryption methods used in the WPT system are therefore reviewed in this study. A study of several techniques reveals that the distance, effectiveness, and quantity of receivers are the primary determinants of the most appropriate energy.

Fast and efficient deterministic quantum state transfer between two remote mechanical resonators

Rezaei, Mojtaba, Kurosh Javidan, Hamidreza Ramezani +1 more

The main challenge in deterministic quantum state transfer in long-distance quantum communications is the transmission losses in the communication channel. To overcome this limitation, here we use the adiabatic theorem and find a lossless evolution path between two remote mechanical modes. By adiabatic variation of the effective coupling strengths between the two nodes and the intermediate optical channel modes, we engineer a transmission path for the quantum state transfer that is decoupled from the decaying fiber modes. Using our proposed method we show that one obtains a quantum state transfer with high efficiency. Furthermore, to bypass the slow nature of the adiabatic process and its sensitivity to the mechanical damping and noise as well as the strength of the driving pulses, we develop the shortcut to adiabatic passage protocol for our proposed quantum state transfer. Our results show that the shortcut to adiabaticity provides an efficient and fast quantum state transfer even for small values of the coupling strength. We show that the performance of our protocol for long-distance quantum communications remains efficient for transferring the quantum states between two remote mechanical resonators being hundred meters apart.

Exploiting Interference for Secrecy Wireless Information and Power Transfer

Yuan Liu, Jie Xu, Rui Zhang

RF signals enabled wireless information and power transfer (WIPT) is a cost-effective technique to achieve two-way communications and at the same time provide energy supplies for low-power wireless devices. However, the information transmission in WIPT is vulnerable to eavesdropping by energy receivers. To achieve secrecy communications with information nodes while satisfying the energy transfer requirement of energy receivers, an efficient solution is to exploit dual use of the energy signals also as useful interference or artificial noise to interfere with the energy receivers, thus preventing their potential information eavesdropping. Toward this end, this article provides an overview on the joint design of energy and information signals to achieve energy-efficient and secure WIPT under various practical setups, including simultaneous WIPT, wireless powered cooperative relaying and jamming, and wireless powered communication networks. We also present some research directions that are worth pursuing in the future.
