Quantum computers promise enormous computational power, but the nature of quantum states makes computation and data inherently "noisy." Rice University computer scientists have developed algorithms that account for noise ...
A research team from Aarhus University, Denmark, has measured and explained the exceptionally low thermal conductivity of the crystalline material AgGaGe3Se8. Despite its ordered structure, the material behaves like a glass ...
In their quest to explore and characterize high-temperature superconductors, physicists have mostly focused on a material that is not the absolute highest. That's because that crystal is much easier to split into uniform, ...
A line of engineering research seeks to develop computers that can tackle a class of challenges called combinatorial optimization problems. These are common in real-world applications such as arranging telecommunications, ...
A study conducted by researchers from the Changchun Institute of Optics, Fine Mechanics and Â鶹ÒùÔºics (CIOMP) of the Chinese Academy of Sciences has demonstrated how nitrogen vacancies (VN) resolve asymmetric carrier injection ...
Electricity flows through wires to deliver power, but it loses energy as it moves, delivering less than it started with. But that energy loss isn't a given. Scientists at Penn State have found a new way to identify types ...
Using new techniques, Yale researchers have demonstrated the ability to use lasers to cool quantized vibrations of sound within massive objects to their quantum ground state, the lowest energy allowable by quantum mechanics. ...
In a new study published in Nature Â鶹ÒùÔºics, scientists have achieved the first experimental observation of phonon angular momentum in chiral crystals.
While conventional computers store information in the form of bits, fundamental pieces of logic that take a value of either 0 or 1, quantum computers are based on qubits. These can have a state that is simultaneously both ...
Just as overlapping ripples on a pond can amplify or cancel each other out, waves of many kinds—including light, sound and atomic vibrations—can interfere with one another. At the quantum level, this kind of interference ...
