Chessboard-like method enables the operation of largest gate-defined quantum dot system
Photograph of the quantum chip hosting the 16 quantum dot crossbar array, seamlessly integrated to a chessboard motif. Every quantum dot, like a pawn on a chessboard, is uniquely identifiable…
Do measurements produce the reality they show us?
According to quantum theory, measurement results are shaped by the changes in the relation between the past and the future of a system caused by the measurement interaction. Credit: Tomonori…
Research group detects a quantum entanglement wave for the first time using real-space measurements
Artistic illustration depicts magnetic excitations of cobalt-phthalocyanine molecules, where entangled electrons propagate into triplons. Credit: Jose Lado/Aalto University Triplons are tricky little things. Experimentally, they’re exceedingly difficult to observe. And…
Advances in quantum emitters mark progress toward a quantum internet
Left, model of the atomic structure of the quantum light-emitting defect in silicon (gray), composed of two substitutional carbon atoms (black), and one silicon interstitial atom (pink). The size of…
Physicists use a 350-year-old theorem to reveal new properties of light waves
Physicists at Stevens Institute of Technology use a 350-year-old theorem that explains the workings of pendulums and planets to reveal new properties of light waves. Credit: Stevens Institute of Technology…
