Quantum physics, the study of the universe on an atomic scale, gives us a reference model to understand the human ecosystem in the discrete individual unit. It helps us understand how individual human behavior impacts collective systems and the security of humanity. Metaphorically, we can see this in how a particle can act both like a particle or a  wave . The concept of entanglement is at the core of much of applied quantum physics. The commonly understood definition of entanglement says that particles can be generated to have a distinct reliance on each other, despite any three-dimensional or 4-dimensional distance between the particles. What this definition and understanding imply is that even if two or more particles are physically detached with no traditional or measurable linkages, what happens to one still...

Snehal Fernandes  ·  06-May-2019 A multinational team of astronomers, led by a Mumbai-based scientist, has solved a long-standing cosmic puzzle: How many years after the Big Bang did the universe achieve conditions that determined and eventually led to the universe we see around us today? The seven-member team, including 35-year-old theoretical physicist Girish Kulkarni from the Tata Institute of Fundamental Research (TIFR), Mumbai, found that the universe finished heating up 12.7 billion years ago by a process called reionisation that occurred due to light from young stars formed in the first galaxies. That’s 1.1 billion years after Big Bang. The paper was published in the April issue of the Monthly Notices of the Royal Astronomical Society, London. “Reionisation led to the universe we see around us,” said Dr Kulkarni, the paper’s lead author. “Without reionisation, the universe would be dark and cold with temperatures close to absolute zero (–273.15 degrees Celsius). The uni...

Knowing how to solve physics problems is a process that can be learned. By    Marcia Wendorf May, 11th 2019 Albert Einstein once said: “The formulation of the problem is often more essential than its solution ...  credits:deposit photos Former Apple CEO Steve Jobs said, "When you start looking at a problem and it seems really simple, you don’t really understand the complexity of the problem. Then you get into the problem, and you see that it’s really complicated, and you come up with all these convoluted solutions. That’s sort of the middle, and that’s where most people stop… But the really great person will keep on going and find the key, the underlying principle of the problem — and come up with an elegant, really beautiful solution that works." Solving problems, whether in physics or other disciplines, can be learned.

Credit: University of Vienna, created by Thomas Rögelsperger A novel material that consists of a single sheet of carbon atoms could lead to new designs for optical quantum computers. Physicists from the University of Vienna and the Institute of Photonic Sciences in Barcelona have shown that tailored graphene structures enable single photons to interact with each other. The proposed new architecture for quantum computer is published in the recent issue of  npj Quantum Information . Photons barely interact with the environment, making them a leading candidate for storing and transmitting  quantum  information. This same feature makes it especially difficult to manipulate information that is encoded in photons. In order to build a photonic quantum computer, one  photon  must change the state of a second. Such a device is called a quantum logic gate, and millions of  logic gates  ...
