Answer 1

real world applications of quantum mechanics.

Quantum random number generator

We come across dice rolling and computer softwares that generate random numbers when we execute them. However, scientists argue that these methods can ultimately be predicted if we are able to crack the softwares and if we are able to study every physical feature of the dice before we roll it. Theoretically, scientists regarded numbers generated by quantum random number generator as truly random because the generator produce a series of numbers based on photoelectric effect (production of electrons after high frequency electromagnetic radiation absorption by certain metals) and quantum noise (uncertainty of some physical quantity due to its quantum origin) which are the natural sources of signals.

This mechanism is able to generate random numbers to encrypt data and to use weather simulators. Do remember random numbers is necessary to select a sample which is bias-free.

Transistors and semiconductors

The quantum tunneling phenomenon applicable in transistors too. Electrons can absorb energy from the surrounding colliding particles and break the barriers that impede their movements. When the barrier breaks, the electrons produce a current that varies exponentially with the electrical field applied. This will open and close the logic gates which are essential for the operations of the computers.

Tunnel diodes

Diodes work based on the principle of voltage bias. This means that there is a higher current in one direction than the other. By applying the concept of quantum tunneling, the diode will be able to work faster
