Using sophisticated optical microscopy techniques developed at Columbia over the past three years, the team was able to directly image these states for the first time, revealing that even at room temperature they are highly tunable and act as quantum dots, tightly confined pieces of semiconductors that emit light.<\/p>\n<p>\u201cOur discovery is very exciting, because it means we can now position a <a href=\"https:\/\/phys.org\/tags\/single-photon\/\" rel=\"tag\" class=\"\">single-photon<\/a> emitter wherever we want, and tune its properties, such as the color of the emitted photon, simply by bending or straining the material at a specific location,\u201d says James Schuck, associate professor of mechanical engineering, who co-led the study published today by <i>Nature Nanotechnology<\/i>. \u201cKnowing just where and how to tune the single-photon <a href=\"https:\/\/phys.org\/tags\/emitter\/\" rel=\"tag\" class=\"\">emitter<\/a> is essential to creating quantum optical circuitry for use in quantum computers, or even in so-called \u2018quantum\u2019 simulators that mimic physical phenomena far too complex to model with today\u2019s computers.\u201d<\/p>\n<p>Developing <a href=\"https:\/\/phys.org\/tags\/quantum+technologies\/\" rel=\"tag\" class=\"\">quantum technologies<\/a> such as quantum computers and quantum sensors is a rapidly developing field of research as researchers figure out how to use the unique properties of quantum physics to create devices that can be much more efficient, faster, and more sensitive than existing technologies.
