Quantum tunneling refers to the phenomenon in quantum mechanics where a particle has a finite probability of crossing through an energy barrier or potential barrier despite lacking the necessary energy to overcome it based on classical physics. This behavior arises due to the wave-like nature of particles at the quantum level. Quantum tunneling allows particles to "tunnel" through barriers, enabling them to reach regions that would be classically inaccessible.
"In quantum computing, qubits can exploit quantum tunneling to tunnel through energy barriers, facilitating more efficient computation processes."
