Quantum communication using a bounded-size quantum reference frame
, 2009 Typical quantum communication schemes are such that to achieve perfect decoding the receiver must share a reference frame with the sender. Indeed, if the receiver only possesses a bounded-size quantum token of the sender's reference frame, then the ...

The Michelson-Morley experiment in an accelerated reference frame [PDF]
, 2010 We analyze the Michelson-Morley experiment in a reference frame moving with constant proper acceleration. Interestingly, we find an expected fringe shift which depends not only on the interferometer's rate of acceleration, but also on its speed relative to a preferred absolute reference frame.

Overall properties of the Gaia DR1 reference frame
, 2017 We compare quasar positions of the auxiliary quasar solution with ICRF2 sources using different samples and evaluate the influence on the {\it Gaia} DR1 reference frame owing to the Galactic aberration effect over the J2000.0-J20015.0 period.

Hierarchical video summarisation in reference frame subspace [PDF]
, 2009 In this paper, a hierarchical video structure summarization approach using Laplacian Eigenmap is proposed, where a small set of reference frames is selected from the video sequence to form a reference subspace to measure the dissimilarity between two ...

On the Observables Describing a Quantum Reference Frame
, 2000 A reference frame F is described by the element g of the Poincare' group P which connects F with a given fixed frame F_0. If F is a quantum frame, defined by a physical object following the laws of quantum physics, the parameters of g have to be ...

Quantifying the resource of sharing a reference frame
, 2005 We define a new quantity called refbit, which allows one to quantify the resource of sharing a reference frame in quantum communication protocols. By considering both asymptotic and nonasymptotic protocols we find relations between refbits and other ...

TDAN: Temporally Deformable Alignment Network for Video Super-Resolution [PDF]
arXiv, 2018 Video super-resolution (VSR) aims to restore a photo-realistic high-resolution (HR) video frame from both its corresponding low-resolution (LR) frame (reference frame) and multiple neighboring frames (supporting frames). Due to varying motion of cameras or objects, the reference frame and each support frame are not aligned.

Robustness of reference-frame-independent quantum key distribution against the relative motion of the reference frames [PDF]
, 2017 Reference-Frame-Independent quantum key distribution (RFI-QKD) is known to be robust against slowly varying reference frames. However, other QKD protocols such as BB84 can also provide secrete keys if the speed of the relative motion of the reference frames is slow enough.

Asynchronous reference frame agreement in a quantum network
, 2016 An efficient implementation of many multiparty protocols for quantum networks requires that all the nodes in the network share a common reference frame. Establishing such a reference frame from scratch is especially challenging in an asynchronous network

Gauge transformation through an accelerated frame of reference
, 2009 The Schr\"{o}dinger equation of a charged particle in a uniform electric field can be specified in either a time-independent or a time-dependent gauge.
