Fast control methods enable record-setting fidelity in superconducting qubit
In an artist’s impression of a recent MIT experiment, a central sphere represents a qubit, which is irradiated by two control signals: charge (blue) and flux (purple). These control signals…
Physicists discover and explain unexpected magnetism in atomically thin material
MIT physicists have created an ultrathin, two-dimensional material with unusual magnetic properties. They did so by working with three layers of graphene. Each layer is composed of only a single…
Collaboration tests new method for protecting quantum networks
Oak Ridge National Laboratory collaborated with commercial utility EPB and the University of Tennessee Chattanooga to develop and test the first transmission of an entangled quantum signal using multiple wavelength…
Quantum breakthrough may lead to sustainable chiral spintronics
Rendering of the tilting of relativistic Dirac cones in the bulk electronic bands of a quasi-two-dimensional (2D) magnetic topological semimetal achieved with insertion of hydrogen that generates tunable low-dissipation chiral…
Record cold quantum refrigerator paves way for reliable quantum computers
The new quantum refrigerator—the square object in the center of the qubit in the image—is based on superconducting circuits and powered by heat from the environment. It can autonomously cool…
Physicists achieve simulation of non-Hermitian skin effect in 2D with ultracold fermions
Atoms accumulate at the edge with non-Hermiticity introduced through dissipation in two dimensions. Credit: HKUST A research team led by The Hong Kong University of Science and Technology (HKUST) has…
