Review: Soulpepper’s ‘Copenhagen’ is a challenging yet rewarding debate Special

Toronto - So why did Werner Heisenberg meet with Niels Bohr in Copenhagen in 1941 – and what were the historical consequences? What was Heisenberg’s real purpose? Why did their friendship end? And did Heisenberg have anything on his conscience?

Key to quantum computing is understanding quantum chaos

A new study indicates that a deeper understanding of quantum chaos could provide the key to unlock the full potential of quantum computers. This is based on studies where researchers have manipulated atoms through a quantum simulator.

Improving LEDs with quantum dots

Zurich - Getting lights to last for longer and remain bright is an important backdrop to furthering the development of many modern technologies. A type of quantum dot could well hold the answer to driving such improvements.

Investment in Swedish quantum computing

A Swedish university has received a large grant to continue its research into developing a quantum computer. This could place Sweden and the Chalmers University of Technology at the forefront of this future technology.

The Grover algorithm: Fine tuning for quantum computing

Another step along the path towards quantum computers has been completed. This is a database search mechanism. The system has recently been tested for future quantum computers at the Karlsruhe Institute of Technology.

Quantum computing advanced with silicon-laced diamonds

Boston - Quantum computing could be advanced through a relatively simple process: the addition of a little silicon to a diamond, which turns diamond defects into efficient quantum bits.

IBM to start building 'universal' quantum computers this decade

IBM has announced it will begin manufacturing mainstream quantum computers within the next few years. The commercial first will see 50-qubit machines go on sale this decade with performance millions of times greater than current desktops.

New data transfer efficiency record set

Computer technologists have set a new record for the transfer of information via superdense coding. This is a process where the properties of particles are used to store as much information as possible.

Microsoft ready to start building scalable quantum computers

Microsoft has announced it is progressing from simply researching quantum computing to actually building machines that run on "qubits." Quantum computing could open up new avenues of scientific research by offering vastly greater performance.

Review: ‘Constellations’ tries to find string theory in relationships Special

Toronto - Not everybody finds quantum physics romantic or sexy. British playwright Nick Payne evidently does, as his acclaimed 2012 stage hit “Constellations” tries to examine different incarnations of a relationship between two scientists.

Deploying lasers to sniff out toxic gas

The days of using dogs to sniff out toxic substances could be about to end. Scientists have pioneered a new approach for toxic gas detection based on infrared lasers, and the scientific explanation is at the quantum level.

Artificial intelligence designs better quantum experiments

Quantum science is so difficult to grasp — even for scientists — that a doctoral student designed an algorithm to better design experiments.

Quantum science helps track explosives

London - Scientists report on a new step towards a more efficient monitoring method, using quantum dots, to quickly sniff out and identify five dangerous compounds.

Scientists show future events decide what happens in the past

An experiment by Australian scientists has proven that what happens to particles in the past is only decided when they are observed and measured in the future. Until such time, reality is just an abstraction.

Op-Ed: Do quantum or classical physics rule? MIT wants to find out

Sydney - The dichotomy between classical Newtonian physics and quantum physics has created more than a few tense debates. Which are the dominant/presiding physical laws? MIT has proposed an experiment to settle this vexed question.

Op-Ed: The God particle has finally been discovered

On Wednesday, 4 July 2012, in Geneva, Switzerland, scientists working at the European Organization for Nuclear Research (CERN) announced that they have found the elusive Higgs boson particles, sometimes referred to as the God particle.

Viennese university physicists create first quantum twin atoms

Vienna - Will the first quantum twin atoms experience quantum entanglement? In the mysterious world of quantum physics, quantum particles, even at a distance, share similar physical properties. Physicists have created the world's first quantum twin atoms.

Physicist: Large Hadron Collider could be used as time machine

Geneva - Physics of the impossible? Or physics of the future? One physicist believes the world's largest atom smasher, the Large Hadron Collider, could double as a time machine that could allow people to go back in time.

Strings of photons are the future of IT encryption

Quantum physics can bring good news to all those who want to conduct totally secure communications over IT networks - particularly financial institutions. Strings of photons are affected when they are observed and this fact can be used in IT encryption.

From Big Bang to Big Bounce- are we living in a recycled universe?

Quantum physics has been added to Einstein’s General Theory of Relativity to produce a model of the creation of the universe. The new theory is called Loop Quantum Gravity. It's about as simple as it sounds.

In the July 14, 1995 issue of Science magazine, researchers from JILA reported achieving a temperature far lower than had ever been produced before and creating an entirely new state of matter predicted decades ago by Albert Einstein and Indian physicist Satyendra Nath Bose. Cooling rubidium atoms to less than 170 billionths of a degree above absolute zero caused the individual atoms to condense into a "superatom" behaving as a single entity.
