Browsing: Qubits
Qubits are the fundamental units of quantum information in quantum computing, analogous to bits in classical computing. Unlike classical bits, which can be either 0 or 1, qubits can exist in a superposition of both states simultaneously, thanks to the principles of quantum mechanics. This property, along with entanglement and quantum interference, enables quantum computers to perform certain types of calculations much faster than classical computers. Qubits can be implemented using various physical systems, such as superconducting circuits, trapped ions, and photonic systems.
