Physicists "entangle" individual molecules for the first time, hastening possibilities for quantum computing
For the first time, a team of Princeton physicists have been able to link together individual molecules into special states that are quantum mechanically "entangled." In these bizarre states, the molecules remain correlated with each other—and can.....»»
Fractal photonic anomalous Floquet topological insulators to generate multiple quantum chiral edge states
An anomalous Floquet topological insulator (AFTI) is a periodically driven topological insulator (TI with nonzero winding numbers to support topological edge modes, though its standard topological invariants like Chern numbers are zero......»»

Rambus launches Quantum Safe Engine for data center and government hardware security
Rambus has unveiled the availability of a Quantum Safe Engine (QSE) for integration into hardware security elements in ASICs, SoCs and FPGAs. Quantum computers will enable adversaries to break current asymmetric encryption, placing important data and.....»»
Counteracting bone and muscle loss in microgravity
In microgravity, without the continuous load of Earth's gravity, the tissues that make up bones reshape themselves. Bone cells readjust their behaviors—the cells that build new bone slow down, while the cells that break down old or damaged bone tis.....»»
