Quantum computing - statistics & facts
Quantum technology works by using the principles of quantum mechanics – the physics of sub-atomic particles – notably quantum entanglement and quantum superposition. Challenging though it may sound, it is not a prerequisite to fully understand quantum in its entirety to benefit from the technology. Essentially, quantum technology has the potential to offer solutions that are faster, more complex, more secure, and more precise than traditional technologies. Sectors exploring quantum technology include telecommunications, aerospace, automotive, life sciences, energy and chemicals, and banking.
Quantum technology segments
The three broader quantum technology segments include quantum computing, quantum communications and security, and quantum sensing. Quantum computing leverages the properties of quantum physics and engineering to perform incredibly advanced calculations and data simulations. Quantum communications involves the protection and transmission of data securely and effectively, making it effectively hacker-proof. Quantum sensing is an advanced sensor technology that detects changes in motion, and electric and magnetic fields, by collecting data at the atomic level, improving accuracy and precision.Quantum computing: solving complex problems better and faster
The largest of these segments is quantum computing, with forecasts suggesting the market for the technology could rise to over 90 billion U.S. dollars. In comparison to traditional computers, quantum computers can perform many computations simultaneously. The basic unit of a classical computer is a bit, only existing in one state at the same time and having either a value of 0 or 1 – the binary system. Qubits, the basic unit in quantum computing, however, are not restrained to just one state: they can be both a 0 and a 1 at the same time and therefore carry out many calculations at the same time. Superposition refers to the concept of qubits existing in multiple states at the same time.Quantum investment and adoption
A variety of funding streams have recognized the potential of quantum technology, with venture capital firms as well as public bodies investing in the field. China and the European Union lead the way in terms of public funding for quantum technology. As a result, it comes as no surprise that China, the Netherlands, and Germany are among the leading countries in terms of quantum adoption, as is the United Kingdom too. Organizations have expressed the greatest interest in building quantum applications for AI, data analytics, simulation, and optimization tasks. Notable quantum uses include rapid drug and vaccine discovery in days instead of years, improved supply chain management through enhanced algorithms, and greater optimization in oil and gas exploration, production, and refinement.
