Technically, quantum computing is the integration of quantum physics, mathematics, and computer science methods for the advancement of computational models. It applies two main quantum properties namely superposition and entanglement, which allows the development of quantum computers. Quantum computing incorporates these behaviors of quantum particles to execute computational technologies that are exponentially faster than classic computers.
Quantum computing, in simple terms, is that it is designed to tackle extremely difficult scientific problems by harnessing computing power far beyond the limit of classical supercomputers. If a classic computer is compared to a hot air balloon in computation speed, a quantum computer is like a Space Shuttle.
Quantum computers excel at running simulations that are impossible for conventional computers, leading to breakthroughs for example water molecules have already been simulated on a quantum computer.
The use of quantum computing in different industries having superfast parallel computing power will produce disruptive results which are of great significance to science and business. It holds the promise of exponentially accelerating the ability of classical computers in solving important social and economic problems. By tapping into this unprecedented computational power, scientists are expected to make new revolutions in artificial intelligence, weather forecasting, drug design.
If you put superconducting quantum computers into use in the pharmaceutical sector it will be able to quickly select the most promising combination of drug molecules from all available drug molecule candidates. Saving time and cost in the development process, Covid19 vaccines, would be able to come sooner and more efficiently to market.
The biggest challenge by far is the changing climate, and it’s worsening impact on food supplies, natural disasters and rising oceans. Quantum computing can unlock new approaches for tackling climate change by contributing to the development of new zero-emission technologies like for example energy production and how we store power.
Hackers and Cybersecurity will battle each other on a quantum computing realm. We now live in a world where cars, hospitals and nuclear missiles run on code — programmers can literally control reality. As the world becomes more digitized, it also becomes more hackable. Cyber attacks, data breaches, even cyber warfare are all very real. Encryption has already been developed that theoretically cannot be broken by quantum computers, and when quantum computers become powerful enough there’ll be a shift to these new algorithms.
