Market Definition
Quantum computing involves phenomena such as quantum entanglement and quantum mechanics superposition that quantum computers use for their enhanced computing power. The improved computing power of quantum computers can be attributed to how data is represented. Conventional computers use bits that can either be 1s or 0s, while quantum computers use qubits (quantum bits), which can be both 0s and 1s simultaneously due to superposition. Quantum computing devices or quantum computers operate with nanoscale components at low temperatures, and they have the potential to address some of the most challenging computational problems.
