A new study from the University of Chicago taps an ingredient most often used in the lithium-ion batteries that power our devices to open new avenues in biomedical technology. Lithium plays vital roles in the body, but taking it orally can have unwanted side effects—so a pair of UChicago chemistry labs teamed up to find a way to deliver lithium only to the exact places where it’s needed.

Their study, published in Nature Materials, could be the foundation for future biomedical technologies to treat p...

Silicon is ubiquitous in modern electronics, and now it is becoming increasingly useful in quantum computing. In particular, silicon’s compatibility with existing chip technology and its long coherence times in silicon-based spin qubits make it a promising material for scalable quantum computing. A new study, published in Nature Nanotechnology, has demonstrated silicon’s use in a logical quantum processor, representing the first of its kind.

Researchers have developed a holographic data storage approach that stores and retrieves information in three dimensions by combining three properties of light—amplitude, phase and polarization. By allowing more data to be stored in the same space, the new approach could help advance efforts to meet the growing global demand for data storage.

Quantum computers, systems that process information leveraging quantum mechanical effects, could outperform classical computers on some advanced tasks. These systems rely on qubits, the fundamental units of quantum information, that become linked via an effect known as quantum entanglement and share a unified quantum state.

Qubits are known to be highly sensitive to slight changes or disturbances in their surrounding environment, also referred to as noise. Noise can prompt them to lose quantum information via a process called decoherence, which in turn leads to errors.

In recent years, quantum scientists and engineers have introduced various approaches aimed at mitigating or correcting quantum errors, with the goal of re...
