Abstract: A system for controlling the temperature of a quantum circuit comprises an enclosure comprising enclosure walls made of temperature conductive material; a substrate for holding a quantum circuit; at least one source of cooling fluid; at least one port in the enclosure coupled to at least one source of cooling fluid; a control unit coupled to at least one source of cooling fluid and configured to control or enable the control of supply of cooling fluid to the chamber; wherein the system in use fills the enclosure with cooling fluid so as to cool the quantum circuit. Preferably, at least one source of cooling fluid is a source of 3He, 4He or a mixture of the two. The invention provides a method and system for optimising the operating temperatures of superconducting quantum circuits and processors and the environment they operate in.

Abstract: Non-limiting examples of the present disclosure relate to service-backed generation and management of digital ruled paper templates in an exemplary application/service such as a notetaking service. As an example, access to a user account of a notetaking service is detected. A digital context associated with the user account is evaluated. An evaluation of the digital context comprises identifying user identity data associated with the user account and analyzing domain specific data of the notetaking service that corresponds with the identified user identity data. The domain specific data may comprise data identifying a specific electronic notebook of the notetaking service. A customized listing of digital ruled paper templates is populated based on an evaluation of the digital context. The customized listing of digital ruled paper templates is transmitted to the client computing device, which surfaces the customized listing of digital ruled paper templates in a user interface of the notetaking service.
