Mammalian tissues are often composed of repeating anatomical units that are polarised by morphogens or directional blood flow. Thus single cells at different tissue coordinates operate in distinct microenvironment.
This spatial diversity enables optimisation of tissue function by allocating different tasks to cells that reside in distinct tissue locations. To explore this spatial division of labor on a genome-wide scale we are combining single cell transcriptomics with in-situ measurements in intact tissues to enable inference of the sequenced cells’ original tissue locations. This approach enables reconstructing global spatial gene expression atlases. I will demonstrate these approaches on two stereotypical and highly structured organs - the liver and the intestinal epithelium.

In quantum information science, it is essential to quantify the quantum characteristics
of quantum systems. Operational quasiprobability has the following properties:
1) direct comparisons of classical and quantum statistics is possible
2) reproduce all quantum theory results
3) it is real-valued function.
In this talk, we will discuss the results of application to nonclassicality of quantum
systems using operational quasiprobability.
In addition, the nonclassical feature of coherent states of light is studied adopting a
multiplexer of on/off detectors and post-selection. The classical model fails to
reproduce the quantum coincident probability. The failure of the classical model
results from the classical description of light, i.e. the divisibility of intensity.

Topological insulators and superconductors are new quantum states of matter that are characterized by nontrivial topological structures of the Hilbert space. Recently, they attract a lot of attention because of the appearance of exotic quasiparticles such as spin-momentum-locked Dirac fermions or Majorana fermions on their edge/surface, which hold promise for various novel applications. In particular, localized zero-energy Majorana mode is expected to obey non-Abelian statistics and enable topological quantum computing. In this talk, I will introduce the basics of those materials and present some of the key contributions we have made in this new frontier, such as the synthesis of bulk-insulating topological insulators, discovery of topological crystalline insulator, and the discovery of nematic topological superconductor.
