Abstract
A method for determining a condition of a quantum computer is described. The method includes the steps of: providing a quantum computing system having a cryogenic chamber with at least one quantum computing chip inside the cryogenic chamber, wherein the at least one quantum computing chip is connected to at least one cable running through the cryogenic chamber; performing a time-domain reflectometry measurement on the cable, thereby obtaining measurement data; and determining a condition of the quantum computing system based on the measurement data obtained from the time-domain reflectometry measurement.

A method for determining a condition of a quantum computing system, the method comprising the steps of:
- providing a quantum computing system having a cryogenic chamber with at least one quantum computing chip inside the cryogenic chamber, wherein the at least one quantum computing chip is connected to at least one cable running through the cryogenic chamber,
- performing a time-domain reflectometry measurement on the at least one cable, thereby obtaining measurement data, and
- determining a condition of the quantum computing system based on the measurement data obtained from the time-domain reflectometry measurement.
A method for determining reference data to be used for determining a condition of a quantum computing system, the method comprising the steps of:
- providing a quantum computing system having a cryogenic chamber with at least one load inside the cryogenic chamber, wherein the at least one load is connected to at least one cable running through the cryogenic chamber,
- performing a time-domain reflectometry measurement on the cable, thereby obtaining reference data, and
- storing the reference data for comparison purposes in a reference database.
A quantum computing system comprising:
- a cryogenic chamber;
- at least one quantum computing chip inside the cryogenic chamber;
- and
- a cable positioned in the cryogenic chamber, wherein the cable is connected with the at least one quantum computing chip,
- wherein the quantum computing system comprises at least one electronic circuit configured to:
- perform a time-domain reflectometry measurement on the cable, and
- determine a condition of the quantum computing system, wherein measurement data from the time-domain reflectometry measurement is used for determining the condition.
