The present invention relates to a waveguide filter having an enhanced property of a specific passband through cross coupling using a resonator, and can set cross coupling in a limited space by providing a notch post, simplify the complexity of a filter by allowing the properties or strength of the cross coupling to be changed according to the position or form thereof, and implement various filter performances.

An HF resonator assembly generates at least two independent alternating magnetic fields in a test volume of a magnetic resonance apparatus. The HF resonator assembly includes a first pair of flat coils that form a first HF resonator and comprise electrical conductor portions that surround a planar surface portion. The flat coils are arranged on opposing sides of the test volume, on coil support plates that are mutually parallel and in parallel with the longitudinal axis. A second pair of flat coils forms a second HF resonator on second coil support plates. The projections of the planar surface portions of the flat coils in each of the first pair of flat coils and the second pair of flat coils overlap in part, but not completely, when viewed in a direction perpendicular to the respective planar surface portions.

The disclosure provides a novel system of storing information using a charged polymer, e.g., DNA, the monomers of which correspond to a machine-readable code, e.g., a binary code, and which can be synthesized and/or read using a novel nanochip device comprising nanopores; novel methods and devices for synthesizing oligonucleotides in a nanochip format; novel methods for synthesizing DNA in the 3 to 5 direction using topoisomerase; novel methods and devices for reading the sequence of a charged polymer, e.g., DNA, by measuring capacitive or impedance variance, e.g., via a change in a resonant frequency response, as the polymer passes through the nanopore; and further provides compounds, compositions, methods and devices useful therein.

A technique relates a superconducting microwave cavity. An array of posts has different heights in the cavity, and the array supports a localized microwave mode. The array of posts includes lower resonant frequency posts and higher resonant frequency posts. The higher resonant frequency posts are arranged around the lower resonant frequency posts. A first plate is opposite a second plate in the cavity. One end of the lower resonant frequency posts is positioned on the second plate so as to be electrically connected to the second plate. Another end of the lower resonant frequency posts in the array is open so as not to form an electrical connection to the first plate. Qubits are connected to the lower resonant frequency posts in the array of posts, such that each of the qubits is physically connected to one or two of the lower resonant frequency posts in the array of posts.

A quantum device for interfacing Lanthanide ions with optical fields or microwave fields or both. The device includes waveguides or resonators or both for optical fields or microwave fields or for both. The device includes at least one surface to which a single customized Lanthanide molecular complex, or an ensemble, layer, multilayer or crystal of such, are attached or bonded. This places the Lanthanide ions within the optical or microwave fields or both. The ability to customize the molecular structure around each Lanthanide ion, and to control their orientation and position and nano-environment in general, enables minimizing the host lattice effects and non-radiative loss channels for each ion, and increasing their homogeneity. Accordingly, the advantages of the present invention include reduced inhomogeneities, narrower linewidths, extended fluorescence and coherence times, and higher operation temperatures. Devices which benefit from the present invention include lasers, amplifiers, sensors, quantum memories, repeaters and quantum information processing devices at optical fields, microwave fields, or both, including bi-directional optical-microwave convertors.
