Quantum computing is costly, which means that smaller companies could be acquired by larger ones. IBM, Google and Microsoft are major operators in the field of quantum computing. Investors are looking for opportunities to invest dollars in improving quantum computers and technology. It has the potential to overcome some of the hardest challenges facing the world. This type of computing only takes days or hours to solve issues that would take billions of years using today's computers. These computers can help discover new things in the areas of healthcare, energy, environment systems and smart materials. A quantum system with thousands of millions of qubits may be needed to find solutions to problems such as global warming and world hunger. Airbus uses quantum computers to help determine the aircraft's most fuel-efficient ascent and descent paths. Pharmaceutical companies use quantum computers to analyze and compare compounds that might lead to new drugs being developed. Quantum computers in factories can provide insights into optimization for streamlined output, reduced waste and lower costs.
