Quantum Superposition Explained with Practical Applications

Updated on September 12, 2014

In quantum mechanics a particle can have infinite number of states. The ability of a particle to occupy all possible states simultaneously is known as quantum superposition. Experiments have confirmed that light particles called photon can change form randomly.

The partical takes one single states only when someone have a look at this partical.Before an consciouness observer have a look at the partical, it every imaginale states possible.


The scientists of university of California conducted an experiment showing that a small strip of metal can have both vibrating and non-vibrating state at the same time. The object remained in a single state only when an observer took a look at it, which means the presence of a conscious observer make the particle to get out of superposition state.

From a practical point of view, quantum superposition phenomena can help to build computer hardware with massive capacity. At present, researchers are developing quantum memory, in which individual bits can be stored simultaneously as both 0.Though the development of quantum technology is still in its infancy, a few researchers have developed quantum memory, which can store both 0 and 1 simultaneously. Another practical application of superposition is producing quantum CPU (central procession unit), making the computing incredibly faster than the modern day computers. If we ever succeed in building quantum computers that will use superposition theory, we will able to predict weather forecast more accurately and efficiently. The other industries that can extract the maximum benefit of quantum power are health care, defense, e-commerce and movie industry.

Experiments on visible objects

A group of scientists at the University of California conducted a research on a tiny piece of metal. They observe that the piece of metal that is barely visible by human eyes shows quantum superposition properties. This is the first experiment in quantum superposition where the researchers used visible object. They found that the small strip of metal can both oscillate and remain stable simultaneously while not being observed, which confirms the superposition state of an object that is barely visible with naked eyes.

Future applications:

We still struggle with predicting weather because of lack of processing power and the way modern day processors work. If quantum superposition becomes a reality we will be able to forecast more accurately. Besides, having higher level of processing power will empower us to discover the unknown parameters that are causing climate change in various parts of our world.

DNA sequencing is a both complex and tedious job. With our current technology, we need weeks to sequence each individual’s DNA. By DNA sequencing we can precisely determine the order of nucleotides of our DNA, which helps to determine cause of many life threatening diseases like Cancers. Quantum superposition can open a dimension in the medical technology and in medicine industry by making DNA sequencing faster and cost-effective.

Human consciousness intrigues us all. Even with our modern technology, we have no way to locate the source of our consciousness. As you already know that quantum superposition is capable of identifying all the possible states, we can this power to simulate how our neuron works and can create all possible neural connection possible to investigate if we can generate inorganic consciousness.

Negative effects of quantum superposition
However, the advancement of quantum computing can negatively affect the field of cryptography. Since a quantum computer will be able to compute much faster than our modern day super-computers, it will be able to decode encrypted messages at unbelievable speed, which will be a serious threat to the secrecy of information traveling in the Internet in encrypted format. Another problem we will face is to develop new software or applications that can run on quantum hardware. The way research is advancing on superposition theory we can predict that we need to wait at least ten more years to see if the quantum computing is going to be a reality or not.

      @teaches12346: I guess we all the capabilities to become something when we start observing our actions.Thank you for your feedback :)

      Your ariticle is fascinating and presents an interesting look at this phenomena. As I understand it, water has the same capabilities at a certain point. You have me thinking!

      I admit that this is a bit over my head. I have heard of Scrodinger's cat because I watch the Big Bang Theory.

      Interesting article. I'm not sure I understand your second paragraph, but the whole subject has always fascinated me. I've seen multiple demonstrations and explanations, but I don't think I ever really delved into the modern day applications of such. Thanks for sharing! Now, what really gets me fascinated, is quantum entanglement! :)
