Stanford physicists have developed a "quantum microphone" so sensitive that it can measure individual particles of sound, called phonons. [39] A team of researchers from the Universities of Manchester, Nottingham and Loughborough has discovered a quantum phenomenon that helps to understand the fundamental limits of graphene electronics. [38] The authors suggest the magnetism, called orbital ferromagnetism, could prove useful for certain applications, such as quantum computing. [37] Scientists from the Skoltech Center for Photonics and Quantum Materials (CPQM) have developed a novel method to fine-tune the optoelectrical properties of single-walled carbon nanotubes (SWCNT) by applying an aerosolized dopant solution on their surface, thus opening up new avenues for SWCNT application in optoelectronics. [36] A DGIST research team discovered a theory that can expand the development of valleytronics technology, which has been drawing attention as a next generation semiconductor technology. [35] To produce the new ultra-thin transistor, calcium fluoride was selected as the insulating material. [34] University of Illinois electrical engineers have cleared another hurdle in high-power semiconductor fabrication by adding the field's hottest material-beta-gallium oxide-to their arsenal. [33] Transistors are tiny switches that form the bedrock of modern computing; billions of them route electrical signals around inside a smartphone, for instance. Quantum computers will need analogous hardware to manipulate quantum information. [32] "The realization of such all-optical single-photon devices will be a large step towards deterministic multi-mode entanglement generation as well as high-fidelity photonic quantum gates that are crucial for all-optical quantum information processing," says Tanji-Suzuki.
