quantum gate

Seven atoms placed in stable line, a step on the way to constructing a quantum gate, at the University of Bonn.

He has also done pioneering research on the reversible quantum gate logic needed to support quantum computers.

The action of the quantum gate is found by multiplying the matrix representing the gate with the vector which represents the quantum state.

An n-qubit (reversible) quantum gate is a unitary mapping U from the space H of n-qubits onto itself.

Victory can be accomplished by sending a spaceship back to Earth, by building a quantum gate back to Earth, or by conquering the star system.

Finally, the Aeon campaign sees the Princess Rhianne (leader of the Aeon) become part of the quantum gate network.

This virus itself disables every quantum gate in the galaxy, stopping superluminal travel for five years, thus allowing the Cybran Nation to flourish without being attacked by the others.

The first implementation scheme for a controlled-NOT quantum gate was proposed by Ignacio Cirac and Peter Zoller in 1995, specifically for the trapped ion system.

The Cybrans plan to use it to destroy the quantum gate network and free their enslaved brethren, while the Aeon seek to use it to broadcast a message of peace to all people.

In quantum computing and specifically the quantum circuit model of computation, a 'quantum gate' (or 'quantum logic gate') is a basic quantum circuit operating on a small number of qubits.

In computing science, the controlled NOT gate (also C-NOT or CNOT) is a quantum gate that is an essential component in the construction of a quantum computer.

Since each application of requires a single oracle query (assuming that the oracle is implemented as a quantum gate), we can find a good entry with just oracle queries, thus obtaining a quadratic speedup over the best possible classical algorithm.

In quantum information processing the Hadamard transformation, more often called Hadamard gate in this context (cf. quantum gate), is a one-qubit rotation, mapping the qubit-basis states and to two superposition states with equal weight of the computational basis states and .
