Scientists at Princeton have developed a new method for creating superconducting qubits using tantalum, significantly increasing their coherence time to 1.68 milliseconds, which is three times longer than current systems, potentially enabling more powerful quantum computing operations. However, challenges such as the scarcity of tantalum remain before these advancements can be widely implemented.
Physicists at Stevens Institute of Technology have developed a precise formula that fully quantifies the wave-like and particle-like behaviors of quantum objects, advancing understanding of wave-particle duality and enabling new applications in quantum imaging and computing.
Researchers at Stevens Institute of Technology have developed a new formula that precisely quantifies the wave-ness and particle-ness of quantum objects, revealing their dual nature and enabling advanced applications in quantum imaging and computing. The formula incorporates coherence as a key variable, allowing for exact measurements and a better understanding of quantum behavior, with potential implications for quantum information technology.
Researchers at EPFL's Photonic Systems Laboratory have developed a hybrid device that combines semiconductor lasers with silicon nitride photonic circuits containing microresonators, resulting in a chip-scale laser source that enhances the performance of lasers and enables the generation of shorter wavelengths. This breakthrough improves the coherence of semiconductor lasers and shifts their output towards the visible spectrum, opening up new possibilities for applications in telecommunications, metrology, and other high-precision fields. The technology has the potential to revolutionize industries such as biomedical imaging and precision timekeeping, and it lays the groundwork for future advancements in laser technology.
Former Attorney General Bill Barr responded to Donald Trump's attacks by mocking the former president's limited verbal skills and lack of coherence. Barr cited Trump's excessive use of adjectives and lack of discipline in his speech. Trump frequently criticizes Barr for not pursuing his claims of voter fraud in the 2020 election, but Barr stated that he did not act because the claims had no merit.
