A novel method and apparatus for long distance quantum communication in realistic, lossy photonic channels is disclosed. The method uses single emitters of light as intermediate nodes in the channel. One electronic spin and one nuclear spin coupled via the contact hyperfine interaction in each emitter, provide quantum memory and enable active error purification. It is shown that the fixed, minimal physical resources associated with these two degrees of freedom suffice to correct arbitrary errors, making our protocol robust to all realistic sources of decoherence. The method is particularly well suited for implementation using recently-developed solid-state nano-photonic devices.

The invention discloses a starch type impregnating compound for electronic grade spun yarns. The impregnating compound is prepared from the following components in percentage by weight: 1.5-4.5 percent of etherified high amylase corn starch with amylose content of 55-70 percent, 1.0-4.0 percent of etherified low amylase corn starch with amylose content of 27-30 percent, 0.10-2.00 percent of hydrogenated cottonseed oil, 0.05-0.80 percent of emulsifier, 0.10-2.00 percent of lubricant, 0.001-0.005 percent of antibacterial agent, and the balance of deionized water. The electronic spun yarns produced by the impregnating compound has the advantages of high operation rate, high yarn breaking strength, proper hardness, low hairiness rate of bobbin yarns, few broken ends in the warping process and the like.

A method and apparatus for polarizing nuclear or electronic spins is disclosed. An analyte is passed near a surface that has a plurality of spin defect centers implanted within 10 nm of the surface. The spin defect centers are exposed to a magnetic field and illumination to produce polarized spins. The polarized spins then induce spin polarization in the analyte.

Apparatus and method establish quantum oscillations at room temperature. A cavity has therein a resonator structure that includes a resonant element and a gain medium. A species of the gain medium has an electronic spin multiplicity capable of supporting a two-level spin system. An optical pump pumps the resonator structure and thereby generates microwave output power through stimulated emission of thermal photons. The species of the gain medium is of a sufficiently high concentration such as to have an ensemble spin-photon coupling rate which exceeds both the cavity mode decay rate and the spin-spin decoherence rate. The optical pump pumps the resonator structure using a short pulse of nanosecond duration, or a burst of approximately a millisecond in duration at relatively low instantaneous optical power, to excite said species of the gain medium into a spin-polarized two-level system that exhibits quantum oscillations in the microwave output power.
