The application of Integrated quantum photonic circuits to quantum photonics, [1] is seen as an important step in developing useful quantum technology. Single die photonic circuits offer the following advantages over bulk optics: Miniaturisation - Size, weight, and power consumption are reduced by orders of magnitude by virtue of smaller system ...
Very-large-scale integration (VLSI) is the process of creating an integrated circuit (IC) by combining millions or billions of MOS transistors onto a single chip. VLSI began in the 1970s when MOS integrated circuit (metal oxide semiconductor) chips were developed and then widely adopted, enabling complex semiconductor and telecommunications technologies.
In optical systems for quantum information processing, the unit of light in a given mode—or photon—is used to represent a qubit. Superpositions of quantum states can be easily represented, encrypted, transmitted and detected using photons.
Among the first proposals of utilizing resource states for optical quantum computing was the Yoran-Reznik protocol in 2003. [4] While the proposed resource in this protocol was not exactly a cluster state, it brought many of the same key concepts to the attention of those considering the possibilities of optical quantum computing and still required connecting multiple separate one-dimensional ...
A metric graph embedded in the plane with three open edges. The dashed line denotes the metric distance between two points and .. A metric graph is a graph consisting of a set of vertices and a set of edges where each edge = (,) has been associated with an interval [,] so that is the coordinate on the interval, the vertex corresponds to = and to = or vice versa.
Graph states are useful in quantum error-correcting codes, entanglement measurement and purification and for characterization of computational resources in measurement based quantum computing models. A graph state is a particular case of a stabilizer state as well as a 2-uniform hypergraph state, a generalization where the edges have ...
The current state of quantum computing [1] is referred to as the noisy intermediate-scale quantum (NISQ) era, [2] [3] characterized by quantum processors containing up to 1,000 qubits which are not advanced enough yet for fault-tolerance or large enough to achieve quantum advantage.
Common integrals in quantum field theory are all variations and generalizations of Gaussian integrals to the complex plane and to multiple dimensions. [ 1 ] : 13–15 Other integrals can be approximated by versions of the Gaussian integral.
