Claim 13:
14. A superconducting quantum computer comprising:
a sample holder; and
a chip on which a superconducting quantum circuit is formed, the chip being disposed in the sample holder, the sample holder comprising:
a base comprising a support structure; and
a PCB in contact with the base, the PCB comprising:
a dielectric;
a front-surface ground formed on a front surface of the dielectric;
a back-surface ground formed on a back surface of the dielectric;
a through hole that penetrates from the front-surface ground to the back-surface ground, the through hole in which a chip is disposed; and,
a conductor that electrically connects the front-surface ground and the back-surface ground, wherein the conductor is disposed on an end face of the through hole;

wherein at least a part of the base below the through hole has a cavity,
the support structure supports a surface of the chip and is electrically connected to the base,
the support structure is disposed in the cavity, and
the base is made of metal.
