Metamaterials are artificially structured materials that can produce innovative optical functionalities such as negative refractive index, invisibility cloaking, and super-resolution imaging. Combining metamaterials with semiconductors enables us to develop novel optoelectronic devices based on the new concept of operation. Here we report the first experimental demonstration of a permeability-c...

High-speed reconfigurable processors incorporating a reconfigurable memory and microprocessor array into a chip have been developed [1]. Such devices use a context-switching method. Their internal reconfigurable memory includes reconfiguration contexts of 16 banks. One bank includes a reconfiguration context used for ALUs that can be changed to others on a clock in nanoseconds. These devices ha...

We propose a deterministic SWAP gate for dual-rail-encoded single photon qubits. The is constructed from waveguide crossings, Mach–Zehnder interferometers and phase shifters which provide the reconfigurability. Through manipulating of shifters, we can apply either or identity gates. As an essential element nearest neighbor qubit networks, has simple structure presents minimal overhead. Providin...

The synthesis of quantum circuits is a complex problem even for circuits with a small number of lines. At present, optimal synthesis is intractable and heuristic methods must be employed. In this paper, we consider the use of templates to simplify a quantum circuit initially found by other means. The templates tool presented here is a general approach to reversible and quantum circuit simplific...

We show that if a language is recognized within certain error bounds by constantdepth quantum circuits over a nite family of gates, then it is computable in (classical) polynomial time. In particular, our results imply EQNC P; where EQNC is the constant-depth analogue of the class EQP. On the other hand, we adapt and extend ideas of DiVincenzo & Terhal [?] to show that, for any family F of quan...

Background Carbon Nanotube Field Effect Transistors (CNTFETs) have high charge sensitivity at room temperature [1]. By using this sensitivity, some nonvolatile memory devices have been demonstrated with charge trapping in SiO 2 gate insulator [2, 3]. Besides, a new design of synapse-like circuit requires a multi-level nonvolatile memory [4]. For this application, and according to its high charg...

We show that if a language is recognized within certain error bounds by constant-depth quantum circuits over a finite family of gates, then it is computable in (classical) polynomial time. In particular, for 0 < ≤ δ ≤ 1, we define BQNC ,δ to be the class of languages recognized by constant depth, polynomial-size quantum circuits with acceptance probability either < (for rejection) or ≥ δ (for a...

A breadth-first search method for determining optimal 3-line circuits composed of quantum NOT, CNOT, controlled-V and controlled-V + (NCV) gates is introduced. Results are presented for simple gate count and for technology motivated cost metrics. The optimal NCV circuits are also compared to NCV circuits derived from optimal NOT, CNOT and Toffoli (NCT) gate circuits. The work presented here pro...
