Rodney,

Thank you for recommending these published articles. We will try to leverage them for the use case document.

Best regards,

Subject: [Qirg] applications: reference frames

Chonggang,

A few references you might want to be familiar with for your applications draft.  I’m not saying “please cite all of these”, but you should probably familiarize yourself with them.  Note that the interface between the Bell pairs (or other distributed states) and the cybernetic system that maintains the relationship to the real world (e.g., up v. down, east v. west, time) is not clear.  Bell pairs are essentially digital, so a lot of work needs to be put in to figure out how to map those states to an outside frame of reference.  But if it can be done, then distributed states will serve as exquisitely sensitive reference frames, improving distributed sensing, including hopefully topics such as long-baseline interferometry (n.b.: there is some controversy over whether the interferometry use works with ordinary, thermal light like that coming from stars, or whether it only works with coherent light, like that coming from lasers).

abstract = {Quantum mechanics imposes a fundamental trade-off between the accuracy of time measurements and the size of the systems used as clocks. When the measurements of different time intervals are combined, the errors due to the finite clock size accumulate, resulting in an overall inaccuracy that grows with the complexity of the set-up. Here, we introduce a method that, in principle, eludes the accumulation of errors by coherently transferring information from a quantum clock to a quantum memory of the smallest possible size. Our method could be used to measure the total duration of a sequence of events with enhanced accuracy, and to reduce the amount of quantum communication needed to stabilize clocks in a quantum network.},

                  used for retrieving astronomical information from an
                  array of telescopes. However, optic loss in the
                  baseline severely limits the length of baseline and
                  thus limits the resolution of interferometers. In
                  this paper, we consider the elimination of optic
                  loss with quantum noiseless linear amplification
                  (NLA). With a success probability of 1.98e-3, one
                  could implement a 100km long baseline interferometry
                  via 1550nm quantum communication. This shows the
                  power quantum information technique and its
                  application in astronomic interferometry. Finally,
                  the comparison with recent entanglement-assisted
                  method is also investigated.},
