Researchers at Centre for Quantum Technologies Create and Probe Single Barium Ions

All the apparatus that fills the laboratory of the Microtraps group at the Centre for Quantum Technologies — three heavy metal optical benches densely packed with lasers, lenses, mirrors and above them shelves full of electronics — has been put into service to produce and probe single ions of Barium.

Study Results Provide New Insights into Precision Quantum Measurement

Scientists who study the ultra-small world of atoms know it is impossible to make certain simultaneous measurements, for example finding out both the location and momentum of an electron, with an arbitrarily high level of precision. Because measurements disturb the system, increased certainty in the first measurement leads to increased uncertainty in the second.

Cause and Effect Situations May Have Far-Reaching Implications in Quantum Mechanics

One of the most deeply rooted concepts in science and in our everyday life is causality; the idea that events in the present are caused by events in the past and, in turn, act as causes for what happens in the future. If an event A is a cause of an effect B, then B cannot be a cause of A.

Physicists Receive Grant to Explore Dark Matter Particles

The eight academics in the University’s particle physics group conduct experiments using the giant CMS and LHCb detectors, deep underground on the Swiss-French border.

Capturing First Images of Landau Levels

Physicists have directly imaged Landau Levels – the quantum levels that determine electron behaviour in a strong magnetic field – for the first time since they were theoretically conceived of by Nobel prize winner Lev Landau in 1930.

Japan Set to Claim Naming Rights for Elusive Atomic Element 113

Over nine years of research to conclusively identify element 113 has borne fruit.

Researchers Redefine Quantum Theory

In an experiment conducted at the Microkelvin Laboratory at the University of Florida, an international research team has overturned an accepted thumb rule in quantum theory to predict the conditions required for the occurrence of transition between two quantum states.

University of Granada Awarded 1.5 million Grant to Develop Quantum Sensor

A group of researchers have collaborated to measure the effects of layers on super-heavy elements. These elements have not yet been discovered in nature. So far, they have been created by bombarding elements in particle accelerators. These elements have an atomic number greater than Z=103, which is higher than the element lawrence.

Portsmouth Astronomers Validate the Existence of Dark Energy

A two-year study conducted by a team of astronomers from the University of Portsmouth and LMU University Munich indicate the probability of existence of dark energy in the universe to be 99.9996%.
