Yes, quantum tunneling is a real problem and has been an increasingly dangerous issue as the nodes shrink. Three interesting proposals to try and mitigate the issue are: 1. TFETs, aka Tunneling FETs, harness the leakage current itself to drive the transistor. 2. Quantum well FinFETs, use the quantum well to constrain the electron movement and circumvent the problem. 3. This is more of a stopgap measure, but the usage of SiGe FinFETs with FD-SOI.
