Introduction to Quantum Computing

Quantum Computing is a multidisciplinary field comprising aspects of computer science, physics, and mathematics that utilizes quantum mechanics to solve complex problems faster than on classical computers. Quantum computing has the capability to sift through huge numbers of possibilities and extract potential solutions to complex problems and challenges.

The field of quantum computing emerged in the 1980s. It was discovered that certain computational problems could be tackled more efficiently with quantum algorithms than with their classical counterparts. 

In particular, a large-scale quantum computer could break widely used encryption schemes and aid physicists in performing physical simulations. however, the current state of the art is largely experimental and impractical.

Such massive computing potential and the projected market size for its use have attracted the attention of some of the most prominent companies. These include IBM, Microsoft, Google, D-Waves Systems, Alibaba, Nokia, Intel, Airbus, HP, Toshiba, Mitsubishi, SK Telecom, NEC, Raytheon, Lockheed Martin, Rigetti, Biogen, Volkswagen, and Amgen.

Quantum computers represent a completely new approach to computing. And while they won’t replace today’s computers, by using the principles of quantum physics, they will be able to solve very complex statistical problems that today’s computers can’t. Quantum computing has so much potential and momentum that McKinsey has identified it as one of the next big trends in tech. Quantum computing alone—just one of three main areas of emerging quantum technology—could account for nearly $1.3 trillion in value by 2035.
