![]() ![]() This allows quantum computers to perform many computations simultaneously.Īnother key principle of quantum computing is entanglement, which allows qubits to become correlated in such a way that the state of one qubit can instantaneously affect the state of another, even if they are physically separated. Unlike classical bits, which can only exist in one of two states (0 or 1), qubits can exist in multiple states simultaneously due to the phenomenon of superposition. What exactly is quantum computing? In brief, it’s a rapidly-emerging technology that harnesses the laws of quantum mechanics to solve complex problems in a more efficient and powerful manner than classical computers.įor some problems, supercomputers aren’t that super.Īt its core, quantum computing relies on the use of quantum bits (qubits) to process and manipulate information. Reilly's book "Milestones in Computer Science and Information Technology". The machine was the first "automatic, general-purpose, electronic, decimal, digital computer," according to Edwin D. (Credit: IBM) What is Quantum Computing?Computing has come a long way since the quantum theory was developed in the 1920s and the first programmable computer, the Electronic Numerical Integrator and Computer ( ENIAC), was built in 1945. Interior of an IBM Quantum computing system. We will also discuss the challenges and risks associated with this technology, as well as what the future holds for it. In this article, we’ll provide an overview of quantum computing, including industries and fields that could be revolutionized by quantum computing. This advantage can potentially transform numerous spheres and make our life better. Quantum computers use qubits instead of classical bits and can perform certain calculations much faster than classical computers. Not so long ago, the limitations of classical computers pushed scientists to develop a new type of computing – quantum computing.
