Core Concepts
A novel 3-qubit system is used to significantly improve the energy retrieval efficiency of quantum energy teleportation compared to the previous 2-qubit model.
Abstract
The paper presents an enhanced quantum energy teleportation (QET) protocol using a 3-qubit system, which achieves significantly higher energy retrieval efficiency compared to the previous 2-qubit model.
Key highlights:
- The authors define a novel 3-qubit Hamiltonian that conforms to the constraints of zero mean energy and anti-commutative properties of the operations on the observables of the sender and receiver.
- The experimental results show an average energy retrieval efficiency of 65.5% by observing only the V operator, which is much higher than the 35.4% efficiency of the 2-qubit system.
- The enhanced QET protocol is implemented on real IBM quantum hardware, and the results are compared to analytical solutions and a quantum simulator, demonstrating good accuracy.
- The authors discuss the implications of their work, including advancements in quantum communication technologies, quantum memory, and the potential emergence of a quantum energy economy.
- The extended QET model overcomes the limitations of the low-energy extraction problem in the minimal 2-qubit QET protocol.
