The rotation operators R x (θ), R y (θ), R z (θ), the phase shift gate P(φ) and CNOT are commonly used to form a universal quantum gate set. The Clifford set {CNOT, H, S} + T gate. The Clifford set alone is not a universal quantum gate set, as it can be efficiently simulated classically according to the Gottesman–Knill … See more In quantum computing and specifically the quantum circuit model of computation, a quantum logic gate (or simply quantum gate) is a basic quantum circuit operating on a small number of qubits. They are the building blocks of … See more Quantum logic gates are represented by unitary matrices. A gate which acts on $${\displaystyle n}$$ qubits is represented by a $${\displaystyle 2^{n}\times 2^{n}}$$ unitary matrix, and the See more There exists an uncountably infinite number of gates. Some of them have been named by various authors, and below follow some of those most often … See more Serially wired gates Assume that we have two gates A and B, that both act on $${\displaystyle n}$$ qubits. When B is put after A in a series circuit, then the … See more The current notation for quantum gates was developed by many of the founders of quantum information science including Adriano Barenco, See more A set of universal quantum gates is any set of gates to which any operation possible on a quantum computer can be reduced, that is, any other unitary operation can be … See more Measurement (sometimes called observation) is irreversible and therefore not a quantum gate, because it assigns the observed … See more WebNov 1, 2002 · The conditional phase-shift gateThe conditional phase-shift gate introduces a phase-shift only if a predetermined condition is satisfied.
