Direct visualization of quantum dots reveals shape of quantum wave function — ScienceDaily

Trapping and controlling electrons in bilayer graphene quantum dots yields a promising platform for quantum information technologies. Researchers at UC Santa Cruz have now achieved the first direct visualization of quantum dots in bilayer graphene, revealing the shape of the quantum wave function of the trapped electrons.

The results, published November 23 in Nano Letters, provide important fundamental knowledge needed to develop quantum information technologies based on bilayer graphene quantum dots.

“There has been a lot of work to develop this system for quantum information science, but we’ve been missing an understanding of what the electrons look like in these quantum dots,” said corresponding author Jairo Velasco Jr., assistant professor of physics at UC Santa Cruz.

While conventional digital technologies encode information in bits represented as either 0 or 1, a quantum bit, or qubit, can represent both states at the same time due to quantum superposition. In theory,

Expected as a technology for visualization of the invisible change of object surfaces such as stress intensity and distribution — ScienceDaily

Under JST Strategic Basic Research Programs, PRESTO researcher Ayumi Ishii, (Toin University of Yokohama, specially appointed lecturer) has developed a photodiode using a crystalline film composed of lead perovskite compounds with organic chiral molecules to detect circularly polarized light without a filter.

A technology to detect “polarization,” or oscillation direction of light can visualize object surfaces with damages, foreign objects, and distortions. Furthermore, detection of “circularly polarized light,” or rotating electric field of light makes it possible for us to identify stress intensity and distribution of objects. Conventional photodiodes for camera or sensor applications cannot detect polarization of light directly, and therefore, various types of filters must be attached on top of the device to separate the information of polarization spatially. These structures cause substantial losses of sensitivity and resolution in the light detection, especially detection of circularly polarized light is heretofore considered difficult. Thus, it has been much desired

Visualization Technology Supports Strong New Home Sales in COVID Era

Building industry representatives attending the recent Paradigm Annual conference heard NAHB Chief Economist Robert Dietz, Ph.D., forecast that the U.S. economy is in the midst of what will likely be a two-year recovery from the 2020 pandemic. Powering the fiscal rebound is a surprisingly robust housing market, with unprecedented buyer interest, tight inventory, and increased sales compared to the same time last year.

While that’s good news for the industry, capitalizing on the upward trend requires that builders address a host of COVID-era challenges, such as adjusting to local and regional social distancing guidelines, homebuyer hesitation about in-person viewings and design sessions, not to mention protecting employee wellbeing. As a result, builders are embracing home visualization technology to address this new normal in home building.

Paradigm Omni, for example, is a virtual home design software that immerses homebuyers in a 3D home design experience and lets them customize their dream
