Enhancing the W State Fusion Process With a To oli Gate and a CNOT Gate via One-Way Quantum Computation and Linear Optics
Creation of large-scale W state quantum networks is a key step for realization of various quantum information tasks. Regarding the photonics technology, a simple optical setup was proposed for the fusion of two W states. Recently it was shown that via a single Fredkin gate, this basic so-called fusion setup can be enhanced. However the main problem was that the probability of success of realiza...
متن کاملOptimal Design of Two-Qubit Quantum Circuits
Current quantum computing hardware is unable to sustain quantum coherent operations for more than a handful of gate operations. Consequently, if near-term experimental milestones, such as synthesizing arbitrary entangled states, or performing fault-tolerant operations, are to be met, it will be necessary to minimize the number of elementary quantum gates used. In order to demonstrate non-trivia...
متن کاملErasure versus teleportation scheme of optical CNOT gate
We clarify the connections between the erasure scheme of probabilistic CNOT gate implementation recently proposed by Pittman, Jacobs and Franson [Phys. Rev. A 64, 062311 (2001)] and quantum teleportation.
متن کاملExperimental realization of a controlled-NOT gate with four-photon six-qubit cluster states.
We experimentally demonstrate an optical controlled-NOT (CNOT) gate with arbitrary single inputs based on a 4-photon 6-qubit cluster state entangled both in polarization and spatial modes. We first generate the 6-qubit state, and then, by performing single-qubit measurements, the CNOT gate is applied to arbitrary single input qubits. To characterize the performance of the gate, we estimate its ...
متن کاملQuantum algorithm design using dynamic learning
We present a dynamic learning paradigm for " programming " a general quantum computer. A learning algorithm is used to find the control parameters for a coupled qubit system, such that the system at an initial time evolves to a state in which a given measurement corresponds to the desired operation. This can be thought of as a quantum neural network. We first apply the method to a system of two...
