Quantum computing just got hotter: One degree above absolute zero
For decades, the pursuit of quantum computing has struggled with the need for extremely low temperatures, mere fractions of a degree above absolute zero (0 Kelvin or -273.15degC). That's because the quantum phenomena that grant quantum computers their unique computational abilities can only be harnessed by isolating them from the warmth of the familiar classical world we inhabit.
From Earth to Mars: Transporting spin information at the speed of light
Scientists have used electrical pulses to manipulate magnetic information into a polarized light signal, a discovery that could revolutionize long-distance optical telecommunications, including between Earth and Mars.
Realizing clean qubits for quantum computers using electrons on helium
Future quantum computers could be based on electrons floating above liquid helium, according to study by a RIKEN physicist and collaborators, appearing in Physical Review Applied.
Scientists suggest new methods to expedite the commercialization of metalens technology
Metalenses, nano-artificial structures capable of manipulating light, offer a technology that can significantly reduce the size and thickness of traditional optical components. Particularly effective in the near-infrared region, this technology holds great promise for various applications such as LiDAR which is called the "eyes of the self-driving car," miniature drones, and blood vessel detectors.
Advancing quantum networks: Study achieves largest photon emission enhancement for single T center to date
Rice University engineers have demonstrated a way to control the optical properties of atomic imperfections in silicon material known as T centers, paving the way toward leveraging these point defects for building quantum nodes for large-scale quantum networks.
