A method includes providing one or more superconducting quantum circuits, and arranging the one or more superconducting quantum circuits in a hermetic enclosure capable of isolating the one or more superconducting circuits from ambient surroundings. The method also includes controlling an environment in the hermetic enclosure to suppress magnetically active surface defects associated with the one or more superconducting quantum circuits. In some aspects, the method further includes introducing an inert gas into the hermetic enclosure to passivate a surface of the one or more superconducting quantum circuits. In other aspects, the method further includes coating a surface of the one or more superconducting circuits with a non-magnetic encapsulation layer. In yet other aspects, the method further includes irradiating the one or more superconducting circuits using ultraviolet light.

    摘要: A soft card provisioning application is instantiated on a device with wireless communications capabilities. A card number for a soft card desired to be provisioned on the device is obtained from a user of the device. An issuer identification number retrieved from the card number is communicated to a provisioning configuration server over an air interface. A provisioning issuer server network address is obtained from the provisioning configuration server based on the issuer identification number. Card issuer specific challenges are presented to the user, and the user's responses to the challenges are received. The challenge responses are communicated to the provisioning issuer server. Soft card image data and personalization data, where the personalization data includes personalized embossed and pre-printed data, are received from the provisioning issuer server over the air interface. The soft card is provisioned for use on the device based on the data received over the air interface.
