While quantum tunneling offers exciting possibilities, it also presents challenges:
Leakage Currents: In nanoscale transistors, unwanted tunneling can cause leakage currents, leading to energy loss and heat dissipation. Fabrication Complexity: Creating devices that harness tunneling requires precise fabrication techniques, which can be complex and costly. Quantum Decoherence: Maintaining coherent quantum states for tunneling-based applications such as quantum computing is a significant challenge due to environmental interference.
