The barrier may be a physically impassable medium, such as an insulator or a vacuum, or a region of high potential energy. Tweet it - http://bit.ly/okHiQ7Facebook it - http://on.fb.me/qA1dYkminutephysics is now on Google+ - http://bit.ly/qzEwc6 And facebook - http://facebook.com/ At its most basic and understandable explanation, quantum tunneling is the mechanical phenomenon where a wave function can propagate through a potential barrier. Imagine that you throw a ball at Quantum tunneling is a phenomenon where an atom or a subatomic particle can appear on the opposite side of a barrier that should be impossible for the particle to penetrate. It's as if you were 3.

This material must not be used for commercial purposes, or in any hospital or medical facility. When early reports had surfaced that Google had achieved quantum supremacy, it was met with skepticism. Even to those that were well-versed in quantum computing, this came as a surprise. To others, like me, the significance of this feat wen Quantum computing uses quantum mechanics to process enormous amounts of data at an unbelievably high rate of speed.

Physics phenomenon where particle passes through barrier.

Quantum tunneling is when a particle escapes a potential barrier that it does not possess the energy to clear. To explain this further, let’s consider what it would look like in the everyday, macroscopic world that surrounds us.

Since you’re sure that the particle can’t escape – it’s not energetic enough to climb over the hill – you leave it to its own devices.

Quantum tunnelling has many technological advantages. This has made us able to see particles at the atomic level. The Scanning tunnelling microscope (STM) works on this principle and has resolution up to 1 Angstrom (a 10,000,000,000th fraction of a meter). The tunneling diodes and tunneling transistors are other devices which use this effect as
