20100264402 | USE OF SACK GEOMETRY TO IMPLEMENT A SINGLE QUBIT PHASE GATE - An implementation of a single qubit phase gate for use in a quantum information processing scheme based on the υ=5/2 fractional quantum Hall (FQH) state is disclosed. Using sack geometry, a qubit consisting of two σ-quasiparticles. which may be isolated on respective antidots, may be separated by a constriction from the bulk of a two-dimensional electron gas in the υ=5/2 FQH state. An edge quasiparticle may induce a phase gate on the qubit. The number of quasiparticles that are allowed to traverse the edge path defines which gate is induced. For example, if a certain number of quasiparticles are allowed to traverse the path, then a π/8 gate may be effected. | 10-21-2010 |

20100264910 | Use of Topological Charge Measurements To Change Between Different Qubit Encodings - A method for changing qubit encoding for implementation of a quantum computational gate is disclosed.

20120258861 | TWISTED TRACK INTERFEROMETER FOR PRODUCING MAGIC STATES - A twisted track interferometer (TTI) for producing magic states is disclosed.

20090315522 | SELF-EXCITED CONTROLLED FREQUENCY GENERATOR SYSTEM WITH BI-DIRECTIONAL CONVERTER - A controlled frequency generating system (CFG) may be constructed with a main generator and an exciter driven by a common shaft. Excitation power may be provided from the common shaft; as distinct from prior-art systems which may require independent excitation power sources. While controlling the output voltage and frequency of the main generator, the bi-directional controller extracts power from a main generator output and may supply the extracted power to supplement excitation power when needed at certain rotational speeds. The controller may extract power from the exciter when, at other rotational speeds, the exciter produces excess power. The extracted excess power may be delivered to the output of the main generator to maintain a desired level of output power at a desired frequency, irrespective of speed of rotation of the CFG. | 12-24-2009 |
