The '''quantum Turing machine''' (QTM) is the quantum mechanical generalization of the classical [[Turing Machine|Turing machine]], introduced by [[David Deutsch]] in 1985. Where a classical Turing machine manipulates bits on a tape according to deterministic or probabilistic transition rules, a QTM manipulates qubits according to unitary quantum evolution. The QTM provides the theoretical foundation for [[Quantum Computing|quantum computing]] and formalizes the [[Church-Turing-Deutsch Principle|Church-Turing-Deutsch principle]]: the claim that any physical process can be simulated by a universal quantum computing device.

Unlike the classical [[Universal Turing Machine|universal Turing machine]], which became a physical reality in the von Neumann architecture, the QTM remains primarily a mathematical construction. Practical quantum computers implement the [[Quantum Circuit|quantum circuit]] model rather than the tape-based QTM. However, the QTM remains essential for theoretical analysis: it defines the complexity class [[BQP]] and provides the reference point for asking whether quantum mechanics changes the fundamental limits of computation. The QTM does not compute functions outside the Turing-computable class — it does not enable [[Hypercomputation|hypercomputation]] — but it may compute certain functions efficiently that classical machines cannot.
