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.

An electrical connector for a multi-wire electrical cable has two or more cable-side electrical contact elements including associated electrical terminals to each of which is to be connected a wire of the electrical cable, and has two or more output-side electrical contact elements, from each of which projects an electrical connector element via which an electrical connection is establishable to a mating connector. An inductive electrical device is disposed between the cable-side and the output-side electrical contact elements. The inductive electrical device is integrally formed with the cable-side and/or the output-side electrical contact elements. The cable-side and the output-side electrical contact elements are electrically connected to each other via the inductive electrical device. The inductive electrical device includes a coil having a plurality of integrally formed windings and/or is at least partially enclosed by a jacket of a plastic material having ferromagnetic material mixed in the plastic material.

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.

A wafer assembly for an electrical connector, and method for making, that has a first and second wafers configured to interlock with one another. Each of the wafers has at least one contact that has a body portion with a mating end for coupling to a mating contact and a tail end opposite the mating end for engaging a printed circuit board where the mating and tail ends extend from opposite sides of the wafer. A conductive spring member is sandwiched between the first and second wafers. The wafer assembly can include one or more electronic components in electrical contact with the spring member and one of the contacts.
