Topological insulators (TIs) are among the hottest topics in condensed matter physics today. They're a bit strange: Their surfaces conduct electricity, yet their interiors do not, instead acting as insulators. Physicists consider TIs the materials of the future because they host fascinating new...

Molecules haven't been used in quantum computing, even though they have the potential to make the ultra-high-speed experimental technology even faster. Their rich internal structures were seen as too complicated, too delicate, too unpredictable to manage, so smaller particles have been used....

A research team discovered a quantum state in which electrons move in a completely new way under a twisted graphene structure. The unique electronic state is expected to contribute to the development of more efficient and faster electronic devices. It may also be applicable to technologies such as...

Phonons, the quantum mechanical vibrations of atoms in solids, are often sources of noise in solid-state quantum systems, including quantum technologies, which can lead to decoherence and thus adversely impact their performance....

A kind of umbilical cord between different quantum states can be found in some materials. Researchers at TU Wien have now shown that this "umbilical cord" is generic to many materials....

The next generation of atomic clocks "ticks" with the frequency of a laser. This is about 100,000 times faster than the microwave frequencies of the cesium clocks which are generating the second at present. These optical clocks are still being assessed, but already now, some are 100 times more...

Researchers at Durham University have successfully demonstrated long-lasting quantum entanglement between molecules, opening new doors for future advancements in quantum computing, sensing, and fundamental physics. The paper is published in the journal Nature....

Physicists have spent more than a century measuring and making sense of the strange ways that photons, electrons, and other subatomic particles interact at extremely small scales. Engineers have spent decades figuring out how to take advantage of these phenomena to create new technologies....

The operation and performance of quantum computers relies on the ability to realize and control entanglement between multiple qubits. Yet entanglement between many qubits is inherently susceptible to noise and imperfections in quantum gates....

UNSW engineers have demonstrated a well-known quantum thought experiment in the real world. Their findings deliver a new and more robust way to perform quantum computations—and they have important implications for error correction, one of the biggest obstacles standing between them and a working...
