Abstract: Systems and methods for quantum clock synchronization are provided. Various embodiments can use time-energy and polarization entangled photons to securely extract the absolute time difference between two remote clocks. In some embodiments, two parties can each have a source of entangled photons. Each party can detect one member of the pair locally and time stamp the detection time, while the other photon gets sent over a common channel (single optical mode) to the other party where the transmitted photon is detected and time stamped. The time stamp values can be shared over an open authenticated channel and each receiver can run a cross-correlation of the detection times. The authenticity and non-spoofability of the timing signal are ensured if each party does not just perform a simple time of arrival measurement but also incorporate polarization measurements whose joint values constitute a Bell test.

Abstract: Methods, devices and systems for providing a user interface in an on-demand software service environment are described. Some implementations involve receiving an indication of a component definition to instantiate. The component definition may be a portion of a component definition data structure. Such implementations may also involve instantiating the provided component, instantiating all remaining attributes of the component definition data structure to produce a component instance data structure and transmitting an intermediate representation of the indicated component to a client device. The intermediate representation may comprise a version of the component instance data structure. The intermediate representation may allow the client device to create an instance of the component in memory.

Some implementations involve receiving a component request from a first client device, locating class-level definition source code for a component definition corresponding to the component request, identifying the component definition within the source code, determining a language of the component definition and selecting a parser according to the language of the component definition. Such implementations may also involve parsing the source code to create the component definition and transmitting an intermediate representation of the requested component to the client device. The intermediate representation may allow the client device to create an instance of the requested component.

The response may include serialized instantiated component definitions, serialized data for the instantiated component definitions and serialized metadata for the instantiated component definitions.

Abstract: Methods, devices and systems for providing a user interface in an on-demand software service environment are described. Some implementations involve displaying a rendered page, detecting the firing of an event in the rendered page and determining an event type for the event. The implementations may also involve ascertaining whether an action associated with the event is implemented in a server-side language or a client-side language, locating handlers for the event according to the event type and performing a handler execution process. These implementations may also involve executing a component re-rendering process to create a re-rendered page and displaying the re-rendered page. The component re-rendering process may be based, at least in part, on output from the handler execution process.
