Professor Jukka Pekola and Doctoral Candidate Bayan Karimi from Aalto University propose a new approach to measure the energy of single microwave photons. These low energy quanta are emitted by artificial quantum systems ...
We've all experienced the principle of feedback—for example, when we use a thermostat in conjunction with a heating system to regulate indoor temperature. The thermostat measures the current temperature, compares it with ...
Scientists at the National Institute of Standards and Technology (NIST) have invented and demonstrated a novel scheme for substantially improving the detection accuracy of information transmitted in pulses of light through ...
In recent times, sustainable development has been the overarching guiding principle of research concerning environmental issues, energy crises, and information and communication technology. In this regard, spintronic devices ...
Laser beams can do more than just heat things up; they can cool them down too. That is nothing new for physicists who have devoted themselves to precision spectroscopy and the development of optical atomic clocks. But what ...
Researchers make key steps towards generating quantum states of sound inside a microscopic device using laser light and single-photon measurements.
Vortices may conjure a mental image of whirlpools and tornadoes—spinning bodies of water and air—but they can also exist on much smaller scales. In a new study published in Science, researchers from the Weizmann Institute ...
The captured electrons typically absorb light in the visible spectrum, so that a transparent material becomes colored under the presence of such centers, for instance in diamond. "Color centers are often coming along with ...
Integrated photonics allow us to build compact, portable, low-power chip-scale optical systems used in commercial products, revolutionizing today's optical datacenters and communications. But integrating on-chip optical gain ...
The color in a diamond comes from a defect, or "vacancy," where there is a missing carbon atom in the crystal lattice. Vacancies have long been of interest to electronics researchers because they can be used as 'quantum nodes' ...
