Date Time Remote control for quantum emitters Quantum technologies are enabled by precise control of the state and interactions of individual quantum objects. Innsbruck physicists have now proposed a way to remotely control the state of individual quantum emitters. The underlying idea, developed by a research group led by Oriol Romero-Isart, is based on chirped light pulses. In order to exploit the properties of quantum physics technologically, quantum objects and their interaction must be prec...

Chinese Regime Rolls Out New Plans to Overtake the US in Technology During the annual meeting of China’s rubber-stamp legislature earlier this month, the Chinese regime proposed new plans to bolster its research and development in critical technology sectors in order to surpass the United States and achieve global dominance. Meanwhile, U.S. think tanks and lawmakers have proposed strategies to counter the threat posed by China’s tech ambitions. According to the Five-Year Plan (2021-2025) re...

New Advances Using Exotic Matter May Lead to Ultrafast Computing February 17, 2021 In the 1960s, an exotic phase of matter known as an excitonic insulator was proposed. Decades later, evidence for this phase was found in real materials. Recently, particular attention has centered on Ta2NiSe5 because an excitonic insulator phase may exist in this material at room temperatures. The substance is made up of the elements tantalum, nickel, and selenium, and has the potential to lead to breakt...

Washington [US], February 16 (ANI): Researchers during a recent study have found a way to use light and a single electron to communicate with a cloud of quantum bits and sense their behaviour. This discovery will help in making it possible to detect a single quantum bit in a dense cloud.

There is an element of wishful thinking in some parts of Asia that a Biden policy will lead to a more coherent and consistent pushback against a rampaging China. This could well be true, but it is unlikely to happen in a hurry. There are a variety of reasons for this. Simply put, the priorities of the new administration are likely to be different from that of his predecessor, both at home and abroad. First and foremost, no American President at this juncture can afford to ignore the reality of ...
