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 both come first. Dr Jacqui … Read more
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 as well at the same … Read more
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 Vienna’s Professor Caslav Brukner have … Read more
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 known as ‘qubits’. Professor Timothy … Read more
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 cantilever. Nature Physics has published … Read more
