**Timeline of quantum computing** — Timeline of quantum computers1970s* 1970 Stephen Wiesner invents conjugate coding.* 1973 Alexander Holevo publishes a paper showing that n qubits cannot carry more than n classical bits of information (a result known as Holevo s theorem or Holevo … Wikipedia

**Nuclear magnetic resonance (NMR) quantum computing** — NMR quantum computing uses the spin states of molecules as qubits. NMR differs from other implementations of quantum computers in that it uses an ensemble of systems, in this case molecules. The ensemble is initialized to be the thermal… … Wikipedia

**Quantum dot cellular automaton** — Quantum Dot Cellular Automata (sometimes referred to simply as quantum cellular automata, or QCA) Any device designed to represent data and perform computation, regardless of the physics principles it exploits and materials used to build it, must … Wikipedia

**Quantum neural network** — Quantum neural networks (QNN) refers to the class of neural network models, artificial or biological, which rely on principles inspired in some way from quantum mechanics.Two different classes may be generally distinguished:#The class of quantum… … Wikipedia

**Quantum technology** — is a new field of physics and engineering, which transitions some of the stranger features of quantum mechanics, especially quantum entanglement, into practical applications such as quantum computing, quantum cryptography, quantum metrology,… … Wikipedia

**Quantum cryptography** — Quantum cryptography, or quantum key distribution (QKD), uses quantum mechanics to guarantee secure communication. It enables two parties to produce a shared random bit string known only to them, which can be used as a key to encrypt and decrypt… … Wikipedia
