Quantum physics, also known as quantum mechanics, is a fairly new sub-branch of physics which is a more detailed study of any physical occurrence or mystery that is constantly happening according to the principles of quantum theories. Quantum physics differs from conventional physics at the quantum realm of atomic and subatomic scales. The study of quantum physics offers a more detailed definition of the relationship between energy and matter.
Several aspects are questioned by the study of quantum physics. These include time travel, parallel universes, consciousness, black holes, atoms, and several other things, which we believe we already understand. Technically, quantum physics bends every truth we currently believe in and raises doubts, which lead us to search for more answers to help us further understand their purposes and meaning.
The superposition theorem is one such example. The superposition theorem states that a physical object such as an electron or atom may exist in all of its possible states, all at the same time, even if it returns the same result when it is measured or observed.
Another principle is the quantum entanglement which is another physical phenomenon that happen when two or more objects have a very strong connection with each other even if they are thousands of miles apart. It is a by-product of the superposition theorem but each object involved has an indefinite state. An example of quantum entanglement would be when a part of an entangled object is measured and the other part or parts, no matter what the case may be, will also have an appropriate correlated value.
One of the controversial studies of quantum physics is quantum tunneling. Quantum tunneling refers to a quantum mechanical phenomenon when a particle is able to tunnel through anything that is supposedly meant to be insurmountable.
The best manifestation of this phenomenon is the nuclear fusion, which takes place in the lifecycle of stars like our Sun. This phenomenon is the slippage of particle between different universes.
In May 16, 2013, Google and NASA announced a partnership with D-Wave Systems to build the world’s first quantum computer. This quantum computer uses a 512-qubit D-Wave 2 processor, which may be used to answer some of our most complex questions. This super computer is meant to solve optimization algorithms and is said to be running thousands of times faster than most of the regular top quality desktop computers. The D-Wave quantum computer has the capacity of providing over 100 different solutions to optimization problems in only half a second whereas a conventional machine will take about thirty minutes.
Quantum physicists are hoping the development of the quantum computer will help us solve some of the most complex of quantum phenomena. The D-Wave computer is kept in a dilution refrigerator inside a facility of NASA that keeps the temperature lower than that of interstellar space. It is meant to give the best answer for optimization problems. These problems provide hundreds of different answers to a specific question. The answer will depend upon various data that will be compared and contrasted to derive the best possible solution.
