She introduces the key idea of the 'Discourse Mode', identifying five modes: Narrative, Description, Report, Information, Argument. These are realized at the level of the passage, and cut across genre lines. The key feature of MUBs is that one cannot, with a single measurement, distinguish a state prepared in one basis through a projection in another basis that is mutually unbiased.

Fig. What makes the classical approach feasible is so-called back-projection and exploits Klyschko’s advanced wave model [59]. is the optical wavelength. Recall that Eve would have guessed the wrong basis 50% of the time. Y. Chen, W.-G. Shen, Z.-M. Li, C.-Q. Note that, evidently, this procedure is inefficient. By way of example, we use Bessel beams as our spatial mode basis and use the example to illustrate the benefits of a given mode set, e.g., the ability to self-heal behind obstacles and to propagate in an almost non-diffracting way over a certain distance [60].

As indicated earlier, we have chosen BG modes as exemplary modes for QKD since they do not only carry OAM, but also include a controllable radial degree of freedom, which assigns some intriguing properties to these basis states: propagation invariance (or non-diffraction) as well as the ability to reconstruct upon encountering obstructions (self-healing).

In order to demonstrate the full capacity of spatial mode encoding in QKD, we expand the dimension of our MUBs. Express 19, 10387–10409 (2011). Tools to prepare and measure spatial modes of bright classical light have since been translated to the quantum regime to implement HD QKD with spatial modes in many dimensions [69–72]. Rev. For this reason, an information basis beyond $d = 2$ dimensions can be constructed using the OAM basis modes. Commun. N. K. Fontaine, R. Ryf, H. Chen, D. T. Neilson, K. Kim, and J. Carpenter, “Laguerre–Gaussian mode sorter,” Nat. To do so, we display a hologram on the SLM and observe the product of the input field and the SLM phase function in the far-field. In the numerical simulation of the key generation, we assumed Alice encoded photons with randomly selected modes from the $\Psi$ or $\Phi$ basis, while Bob measured in a random basis that is also chosen between $\Psi$ or $\Phi$. How close we stand to someone, whether we touch them, and how comfortable we feel are all part of the study of proxemics. D.
