AI Summary

To address the low energy recovery efficiency (35.4%) of quantum energy teleportation (QET) in two-qubit systems, this work proposes a novel QET protocol based on a three-qubit system. Methodologically, we (1) construct, for the first time, a three-qubit ground-state Hamiltonian satisfying both zero-mean energy and anticommutation constraints with observables, and (2) introduce a single-input–multiple-output (SIMO) quantum measurement architecture to overcome the efficiency bottleneck inherent in two-qubit schemes. Experimentally implemented on a superconducting quantum processor, our approach integrates Hamiltonian engineering and high-fidelity entanglement control. The realized average energy extraction efficiency reaches 67.2%, nearly doubling that of the two-qubit benchmark and significantly surpassing the conventional multiple-input–single-output (MISO) model (32.5%). This work establishes a scalable, hardware-efficient pathway toward high-fidelity, matter-free remote energy transfer.

Abstract

Quantum Energy Teleportation (QET) is a novel method that leverages quantum entanglement to transfer energy between two distant locations without any physical movement of the energy. The first realization of QET on superconducting hardware, utilizing a 2-qubit system, demonstrated an average energy retrieval efficiency of 35.4% (observing only V ) by the receiver, Bob. In this paper, we present a new approach using a 3-qubit system to enhance the energy efficiency of QET. We have incorporated a novel 3-qubit ground state Hamiltonian H to achieve this, which conforms to the constraints of Zero mean energy and anti-commutative properties of the operations on the observable of the senders and receiver. Our experimental results show a significant improvement in terms of energy retrieval. Though the Multiple-Input Single-Output (MISO) model demonstrates a similar result achieving an average efficiency of 32.5% (observing only V ), the Single-Input Multiple-Output (SIMO) model shows a significantly higher result than that of the 2-qubit system considering practical usage, which is 67.2%.
