Quantum computing is a computing paradigm that uses quantum-mechanical phenomena, such as superposition and entanglement, to perform computations. Quantum computing has the potential to solve complex problems that are currently intractable for classical computers. Popular quantum computing platforms include IBM Quantum, Google Quantum, and Microsoft Quantum. See our pricing A transistor is a semiconductor device that can amplify or switch electronic signals. It is composed of a semiconductor material, usually silicon, and is widely used in modern electronic devices.
