The controllable splitting of a single Cooper pair in a hybrid quantum dot system
An abstract diagram of two types of Cooper pair splitters. The conventional Cooper pair splitter (including the faded parts of the diagram) consists of a superconducting contact separated from two…
Exploring spin-orbit coupled Bose-Einstein condensates
A spin microemulsion phase found in simulations of Rashba spin-orbit coupled, Bose-Einstein condensates. Colored regions correspond to dense regions of atoms with the same spin state. Credit: Ethan McGarrigle (doi:…
Study observes strong noise correlations between silicon qubits
Characterization of qubit error correlation in a silicon qubit array. Credit: Yoneda et al To build highly performing quantum computers, researchers should be able to reliably derive information about the…
Optical fiber–based, single-photon light source at room temperature for next-generation quantum processing
Schematic diagram and microscopic observation of an optical fiber doped with rare-earth atoms. The fluorescence from the entire optical fiber can be seen. (b) Schematic diagram and microscopic observation of…
What a ‘2D’ quantum superfluid feels like to the touch
The experiments were carried out at about a 10000th of a degree above absolute zero in a special refrigerator and made use of mechanical resonator the size of a finger…
Simulating spins, spirals and shrinking devices for new classes of energy-efficient materials
Helimagnets are a set of naturally occurring materials in which the electrons arrange themselves into spirals. Some tiny electrically-conducting helimagnets could mimic an inductor—coils of wire that control the flow…
Theoretical modeling illuminates a new nonlinear Hall Effect
(a) Shows how the materials are layered in the heterostructure with six magnetic MBT septuple layers (SLs) and BP layers on top and bottom. (b) Shows atom arrangement in a…
