Quantum Build-Tech planning to expand, diversify business activities

Quantum Build-Tech is planning for expansion and diversification of business activities of the company. The meeting of Board of Directors of the company will be held on October 27, 2018, to consider the same. Quantum Build-Tech is a public limited company listed with Hyderabad & Bangalore Stock Exchanges. Initially the ... Read More »

How long does a quantum jump take?

Quantum jumps are usually regarded to be instantaneous. However, new measurement methods are so precise that it has now become possible to observe such a process and to measure its duration precisely — for example the famous ‘photoelectric effect’, first described by Albert Einstein. It was one of the crucial ... Read More »

Quantum-level control of an exotic topological quantum magnet

Quantum particles can be difficult to characterize, and almost impossible to control if they strongly interact with each other — until now. An international team of researchers led by Princeton physicist Zahid Hasan has discovered a quantum state of matter that can be “tuned” at will — and it’s 10 ... Read More »

Scientists ‘teleport’ a quantum gate

Yale University researchers have demonstrated one of the key steps in building the architecture for modular quantum computers: the “teleportation” of a quantum gate between two qubits, on demand. The findings appear online Sept. 5 in the journal Nature. The key principle behind this new work is quantum teleportation, a ... Read More »

Could a ‘demon’ help create a quantum computer?

Reduced entropy in a three-dimensional lattice of super-cooled, laser-trapped atoms could help speed progress toward creating quantum computers. A team of researchers at Penn State can rearrange a randomly distributed array of atoms into neatly organized blocks, thus performing the function of a “Maxwell’s demon” — a thought experiment from ...

Quantum weirdness in ‘chicken or egg’ paradox

The “chicken or egg” paradox was first proposed by philosophers in Ancient Greece to describe the problem of determining cause-and-effect. Now, a team of physicists from The University of Queensland and the NÉEL Institute has shown that, as far as quantum physics is concerned, the chicken and the egg can ... Read More »

Superradiance: Quantum effect detected in tiny diamonds

The effect has been predicted theoretically decades ago — but it is very hard to provide experimental evidence for it: “Superradiance” is the phenomenon of one atom giving off energy in the form of light and causing a large number of other atoms in its immediate vicinity to emit energy ...

Quantum leap for Einstein’s scientific principle

How Einstein’s equivalence principle extends to the quantum world has been puzzling physicists for decades, but a team including a University of Queensland researcher has found the key to this question. UQ physicist, Dr Magdalena Zych from the ARC Centre of Excellence for Engineered Quantum Systems, and the University of ... Read More »

Making light work of quantum computing

Light may be the missing ingredient in making usable quantum silicon computer chips, according to an international study featuring a University of Queensland researcher. The team has engineered a silicon chip that can guide single particles of light — photons — along optical tracks, encoding and processing quantum-bits of information ... Read More »

Novel approach to coherent control of a three-level quantum system

For the first time, researchers were able to study quantum interference in a three-level quantum system and thereby control the behavior of individual electron spins. To this end, they used a novel nanostructure, in which a quantum system is integrated into a nanoscale mechanical oscillator in form of a diamond ... Read More »
