Overview on quantum initiatives worldwide

Posted by in categories: innovation, quantum physics

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 It might be outdated by now, but it gives an idea 💡 and add to it the latest announced investments.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.

Xi stresses advancing development of quantum science and technology

Posted by in categories: policy, quantum physics, science

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.

‘Classified knots’: Researchers create optical framed knots to encode information

Posted by in categories: encryption, quantum physics, security

In a world first, researchers from the University of Ottawa in collaboration with Israeli scientists have been able to create optical framed knots in the laboratory that could potentially be applied in modern technologies. Their work opens the door to new methods of distributing secret cryptographic keys—used to encrypt and decrypt data, ensure secure communication and protect private information. The group recently published their findings in Nature Communications.

“This is fundamentally important, in particular from a topology-focused perspective, since framed knots provide a platform for topological quantum computations,” explained senior author, Professor Ebrahim Karimi, Canada Research Chair in Structured Light at the University of Ottawa.

“In addition, we used these non-trivial optical structures as information carriers and developed a security protocol for classical communication where information is encoded within these framed knots.”

Research team discovers uniquely quantum effect in erasing information

Posted by in categories: computing, quantum physics

Researchers from Trinity have discovered a uniquely quantum effect in erasing information that may have significant implications for the design of quantum computing chips. Their surprising discovery brings back to life the paradoxical “Maxwell’s demon,” which has tormented physicists for over 150 years.

The thermodynamics of computation was brought to the fore in 1961 when Rolf Landauer, then at IBM, discovered a relationship between the dissipation of heat and logically irreversible operations. Landauer is known for the mantra “Information is Physical,” which reminds us that information is not abstract and is encoded on physical hardware.

The “bit” is the currency of information (it can be either zero or one) and Landauer discovered that when a bit is erased there is a minimum amount of heat released. This is known as Landauer’s bound and is the definitive link between information theory and thermodynamics.

Turning Diamond Into Metal – For Improved Solar Cells, LEDs, and Power Electronics

Posted by in categories: quantum physics, solar power, sustainability

Normally an insulator, diamond becomes a metallic conductor when subjected to large strain in a new theoretical model.

Long known as the hardest of all natural materials, diamonds are also exceptional thermal conductors and electrical insulators. Now, researchers have discovered a way to tweak tiny needles of diamond in a controlled way to transform their electronic properties, dialing them from insulating, through semiconducting, all the way to highly conductive, or metallic. This can be induced dynamically and reversed at will, with no degradation of the diamond material.

The research, though still at an early proof-of-concept stage, may open up a wide array of potential applications, including new kinds of broadband solar cells, highly efficient LEDs and power electronics, and new optical devices or quantum sensors, the researchers say.

Could Schrödinger’s cat exist in real life? Our research may soon provide the answer

Posted by in categories: mathematics, particle physics, quantum physics

Have you ever been in more than one place at the same time? If you’re much bigger than an atom, the answer will be no.

But atoms and particles are governed by the rules of quantum mechanics, in which several different possible situations can coexist at once.
