Over the past decade, scientists have made tremendous progress in generating quantum phenomena in mechanical systems. What seemed impossible only fifteen years ago has now become a reality, as researchers successfully create quantum states in macroscopic mechanical objects. /news/2023-08-quantum-mechanical-oscillator-technology.html Quantum Â鶹ÒùÔºics Fri, 11 Aug 2023 11:01:42 EDT news610970497 Edge states are an emerging concept in physics and have been explored as an efficient strategy to manipulate electrons, photons and phonons for next-generation hybrid electro-optomechanical circuits. Scientists have used gapless chiral edge states in graphene or graphene-like materials to understand exotic quantum phenomena such as quantum spin or valley Hall effects. In a new report now published on Science Advances, Xiang Xi and colleagues reported on experimental chiral edge states in gapped nanomechanical graphene; a honeycomb lattice of free-standing silicon nitride nanomechanical membranes with broken spatial inversion symmetry (presence of a dipole). The constructs were immune against backscattering in sharp bends and exhibited the valley-momentum locking effect. The team realized a smooth transition between the chiral edge states and the well-known valley kink states to open the door for experimental investigations of soft graphene-related physics in very-high-frequency, integrated nanomechanical systems. /news/2021-01-chiral-edge-states-gapped-nanomechanical.html Nanophysics Nanomaterials Fri, 22 Jan 2021 09:30:02 EST news530525022 Researchers led by Delft University of Technology personnel have made two steps in the conversion of quantum states between signals in the microwave and optical domains. This is of great interest for connecting future superconducting quantum computers into a global quantum network. This week they report on their findings in Nature Â鶹ÒùÔºics and in Â鶹ÒùÔºical Review Letters. /news/2019-10-horizons-future-quantum-network.html Quantum Â鶹ÒùÔºics Wed, 09 Oct 2019 07:30:54 EDT news489825047
