    Time-resolved Coulomb collision of single electrons

    A series of recent experiments have shown that collision of ballistic electrons in semiconductors can be used to probe the indistinguishability of single-electron wavepackets. Perhaps surprisingly, their Coulo...

    Continuous-variable tomography of solitary electrons

    A method for characterising the wave-function of freely-propagating particles would provide a useful tool for develo** quantum-information technologies with single electronic excitations. Previous continuous...

    Momentum-dependent power law measured in an interacting quantum wire beyond the Luttinger limit

    Power laws in physics have until now always been associated with a scale invariance originating from the absence of a length scale. Recently, an emergent invariance even in the presence of a length scale has b...

    Controlled spatial separation of spins and coherent dynamics in spin-orbit-coupled nanostructures

    The spatial separation of electron spins followed by the control of their individual spin dynamics has recently emerged as an essential ingredient in many proposals for spin-based technologies because it would...

    Nonlinear spectra of spinons and holons in short GaAs quantum wires

    One-dimensional electronic fluids are peculiar conducting systems, where the fundamental role of interactions leads to exotic, emergent phenomena, such as spin-charge (spinon-holon) separation. The distinct lo...

    All-electric all-semiconductor spin field-effect transistors

    Two quantum point contacts are used to respectively inject and detect spins by purely electrical means in an all-semiconductor spin transistor.

    Gigahertz quantized charge pum** in graphene quantum dots

    Single-electron pumps are set to revolutionize electrical metrology by enabling the ampere to be redefined in terms of the elementary charge of an electron1. Pumps based on lithographically fixed tunnel barriers ...

    Towards a quantum representation of the ampere using single electron pumps

    Electron pumps generate a macroscopic electric current by controlled manipulation of single electrons. Despite intensive research towards a quantum current standard over the last 25 years, making a fast and ac...
