Albert Einstein’s twin paradox is one of the most famous thought experiments in physics. It postulates that if you send one of two twins on a return trip to a star at near light speed, they will be younger than their identical sibling when they return home. The age difference is a consequence of something called time dilation, which is described by Einstein’s special theory of relativity: the faster you travel, the slower time appears to pass.

But what if we introduce quantum theory into the problem? Physicists Alexander Smith of Saint Anselm College and Dartmouth College and Mehdi Ahmadi of Santa Clara University tackle this idea in a study published today in the journal Nature Communications. The scientists imagine measuring a quantum atomic clock experiencing two different times while it is placed in superposition—a quirk of quantum mechanics in which something appears to exist in two places at once. “We know from Einstein’s special theory of relativity that when a clock moves relative to another clock, the time shown on it slows down,” Smith says. “But quantum mechanics allows you to start thinking about what happens if this clock were to move in a superposition of two different speeds.”

Physicists describe a way to merge quantum theory with Einstein’s special theory of relativity—and even a method to test it experimentally.

The double slit experiment — Does consciousness create reality? Quantum mechanics shows us that particles are in superposition, meaning they can exist in different states and even multiple places at the same time. They are nothing more than waves of probabilities, until the moment that they are measured. One interpretation of this phenomenon is that the measurement being made requires a measurer, or a conscious observer. If this is correct, then it implies that consciousness has to be is an integral part of creating the world that we observe. Could this consciousness then be required for creating reality? Does this mean that there would be no reality without consciousness?

Experiments can show that what we think of as particles behave like waves. Waves of probabilities. This is the foundation of Quantum mechanics. The famous double slit experiment illustrates this. What is bizarre is that when you try to find out what’s going on at the slits by placing a detector at the two slits to try to figure out which slit the individual atoms are going through – the “WHICH WAY” information, they all of a sudden stop behaving like waves, and behave like particles.

Researchers led by Technische Universität Kaiserslautern (TUK) and the University of Vienna successfully constructed a basic building block of computer circuits using magnons to convey information, in place of electrons. The ‘magnonic half-adder’ described in Nature Electronics, requires just three nanowires, and far less energy than the latest computer chips.

A team of physicists are marking a milestone in the quest for smaller and more energy-efficient computing: they developed an integrated circuit using magnetic material and magnons to transmit binary data, the 1s and 0s that form the foundation of today’s computers and smartphones.

The new circuit is extremely tiny, with a streamlined, 2-D design that requires about 10 times less energy than the most advanced computer chips available today, which use CMOS technology. While the current magnon configuration is not as fast as CMOS, the successful demonstration can now be explored further for other applications, such as quantum or neuromorphic computing.

Recent experiments show that particles should be able to go faster than light when they quantum mechanically “tunnel” through walls.

Over the last years, there has been an exponential increase in investment in quantum technologies worldwide. The global effort for #publicfunding has been boosted. It is an amazing and exciting time of innovation in this new second quantum revolution. We have summarised the main programs and efforts around the world below. It is not a quantum race. It is a global ecosystem to develop new #quantum technology! It might be outdated by now, but it gives an idea 💡 and add to it the latest announced investments. However, this is not the real deal. Most are disguised under other initiatives such as the ones carried by the DOE in the US.

President Xi Jinping, also general secretary of the Communist Party of China (CPC) Central Committee, has stressed the importance and urgency of advancing the development of quantum science and technology. Xi made the remarks while presiding over a group study session of the Political Bureau of the CPC Central Committee on Friday. Quantum mechanics is a fundamental theory which has been used successfully in explaining microscopic phenomena in all branches of physics. Experts believe the whole world is on the brink of a quantum revolution. Xi noted that China has made breakthroughs in some of the key areas, but still faces multiple challenges. He stressed the need to develop self-reliant technology in order to secure a stable supply chain. More support should be given to the industry in areas including development policy, talent recruiting, academic environment and so on, said Xi.
