A connection system for a quantum computer that employs constant impedance connectors with attenuation or filtering components or both embedded therein or within an adaptor removably insertable within an adaptor housing for use in a cryogenically cooled quantum computer. The connection system provides a higher density of cables traversing through a hermetic sealed top plate, and which are accessible to chill blocks to reduce the thermal energy from the signal lines. Attenuators or filter circuits are embedded in the constant impedance connector housings, or provided in adaptors that connect on each end to form mating constant impedance connections, in order to reduce signal strength as the signal progresses through the cryogenic environment and to remove extraneous electrical signal noise.

A connector is equipped with a housing capable of being fitted in a mating connector which houses a plurality of mating terminals connected to each other electrically and a holder which is attached to the housing. The housing has a plurality of terminal housing rooms which house a plurality of terminals. The holder has a plurality of noise reduction member holding rooms which hold a plurality of noise reduction members each of which reduces noise occurring in a corresponding one of the plurality of terminals housed in the plurality of terminal housing rooms, in such a manner that the plurality of noise reduction members are disposed adjacent to front end surfaces of corresponding ones of the plurality of terminals in a state that attachment of the holder to the housing is completed.

AC inlets that have a low profile, are able to withstand side-to-side and axial forces, and are readily manufactured. An example can provide an AC inlet having a low-profile by providing power and ground prongs where the power and ground prongs are attached to flanges that can extend laterally from a back end of each prong. This lateral distribution of power and ground can reduce a depth of the AC inlet and provide the AC inlet with a low profile.

A noise filter includes a filter circuit including a noise reduction element that reduces a noise component, a conductive first circuit connection member to which a first connection portion of the noise reduction element is electrically connected, and a conductive second circuit connection member to which a second connection portion of the noise reduction element is electrically connected, a first electric connection structure that electrically connects an intermediate connection portion of a core wire of a first electric wire to the first circuit connection member, and a second electric connection structure that electrically connects an intermediate connection portion of a core wire of a second electric wire whose one end is grounded, to the second circuit connection member.

An electrical connector for a multi-wire electrical cable includes at least two cable-side electrical contact elements including associated terminals to each of which is connected a wire of the electrical cable, and at least two output-side electrical contact elements, from each of which projects an electrical connector element by which a mating connector is electrically connectable. A tubular outer conductor extends along a longitudinal direction from a cable-side end to an output-side end and encloses the cable-side and output-side contact elements. At least one stranded drain wire of the electrical cable contacts a shield of the electrical cable and is guided to the electrical connector separately from the wires of the electrical cable. The outer conductor has at least one second slot extending along the longitudinal direction of the outer conductor, and the drain wire is received in the second slot in the outer conductor.
