How is a Quantum Computer different from yours?

How is a Quantum computer different from the computers we use today? They’re much faster, more complex and far more expensive.

Multi-state structure supports more adaptable algorithms

Quantum computing is based on a non-binary system where an atomic piece of data – like the bit – can have any possible number of states, rather than a simple 0 or 1. Quantum atomic data is called a qubit and its structure is somewhat like that of a molecule. This is significant because it enables us to represent and process massive complex data more effectively.

Data structured in this unique way can help us understand complex information that is difficult and unruly to work with even on the largest super computers. A topological approach based on data features can make representation intuitive, thus enabling us to extract valuable knowledge from huge data sets with elegance and simplicity.

What kind of outcomes can be expected from this revolutionary type of computing?

The Institute for Advanced Study advises that quantum computers would likely prove useful for needle in the haystack problems, completing them in 1 thousandth of the time a conventional search might take.

A quantum computer can be in multiple states at the same time. This enables parallel processing without parallel processors. It sounds fast and effective, but the problem arises in accessing the results. Why? Because by accessing just a single result the others disappear. Quantum interference solves this problem by combining multiple results into meaningful and measurable data.

Is a Quantum Computer different or better?

Quantum computers are expected to revolutionize artificial intelligence, transportation, space exploration, medicine and the development of pharmaceuticals, but they won’t be cheap. The price tag is not within the realm of most consumers or small businesses.

In 2014 Time Magazine discussed the $10 million cost of the first quantum computer. It was built by the Canadian Company D-Wave, in collaboration with the CIA, Jeff Bezos of Amazon and NASA. These colossal data users were the perfect partners because of the massive amounts of data they process.

A quantum computer may  be in your future if you use Amazon products, use any kind of transportation or appreciate space research and technology.
