Abstract

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.

Dependent claims

A connection system for transmitting signal cables through tiered stages, wherein at least one stage comprises:

a first signal cable having a center conductor terminated by a first constant impedance receptacle connector or first constant impedance plug connector;
a first connector housing for securing said first signal cable;
a header housing mounted to a first plate, said header housing having a first header housing constant impedance receptacle connector or a first header housing constant impedance plug connector mounted on a first side, and a second header housing constant impedance receptacle connector or a second header housing constant impedance plug connector mounted on a second side opposite said first side, wherein said first header housing connector on said first side is complementary to said first constant impedance receptacle connector or said first constant impedance plug connector of said first signal cable, such that said first connector housing attaches to said header housing on said first side in a constant impedance cable connection;
and
a second connector housing a second signal cable, wherein said second signal cable has a center conductor terminated by a second constant impedance receptacle connector or second constant impedance plug connector, wherein said second connector housing second signal cable connector is a complementary connector to said header housing constant impedance receptacle connector or header housing constant impedance plug connector on said second side, such that said second connector housing attaches to said header housing on said second side in a constant impedance cable connection.

mounting said header housing to a first plate,
connecting a second signal cable to a second connector housing, wherein said second signal cable has a center conductor terminated by a second constant impedance receptacle connector or second constant impedance plug connector, wherein said second connector housing second signal cable connector is a complementary connector to said header housing constant impedance receptacle connector or said header housing constant impedance plug connector on said second side, such that said second connector housing attaches to said header housing on said second side in a constant impedance cable connection;
and
mounting said second connector housing to said header housing.
