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%.
