Smart atomic cloud solves Heisenberg’s observation problem
And this problem - which has to do with the fact that in-accuracies inevitably taint certain measurements conducted at quantum level - is described in Heisenberg’s Uncertainty Princi...
Quantum teleportation is even weirder than you think
Whatever it’s called, the process transfers the quantum state of one particle onto another, identical particle, and at the same time erases the state in the original. Crucially, howe...
Quantum mechanics inside Earth’s core
Flowing of liquid metal in the outer core can intensify electric currents and create Earth’s magnetic field – at least according to the common geodynamo theory. Band-structure induce...
Probability that the quantum world obeys local realism is less than one in a billion, experiment shows
Three Bell tests The test reported here is the latest loophole-free Bell test: one that simultaneously closes the two biggest loopholes, the locality loophole and the detection loop...
Physicists accelerate plans for a new Large Hadron Collider three times as big
Credit: CERN An international league of scientists is kicking off the decades-long process of developing the successor to the Large Hadron Collider, the world’s largest and most pow...
Niels Bohr: Biography & Atomic Theory
Right: Antonio Abrignani Niels Bohr was one of the foremost scientists of modern physics, best known for his substantial contributions to quantum theory and his Nobel Prize-winning ...
More than the sum of its parts: the ATLAS Experiment looks inside the proton
Measured inclusive jet cross section as a function of the jet transverse momentum. It depicts the proton (and other hadrons) as a system of elementary particles, in this case quarks ...
Measured for the first time: Direction of light waves changed by quantum effect
The ‘quantized magneto-electric effect’ has been demonstrated for the first time in topological insulators at TU Wien, which is set to open up new and highly accurate methods of meas...
Magnetic switch turns strange quantum property on and off
But when an applied magnetic field reaches a critical value, it acts as a switch, altering the shape of the orbits and causing the electrons to possess different physical properties ...
LHC’s objective—maximum intensity
Trains of proton bunches have been circulating in the machine for the past week. Despite the ultra-high vacuum, residual gas molecules and electrons remain trapped on the walls of th...
How the quantum Zeno effect impacts Schroedinger’s cat
Credit: Washington University in St. Louis You’ve probably heard about Schrödinger’s cat, which famously is trapped in a box with a mechanism that is activated if a radioactive atom...
First practical building blocks for a global quantum internet
Erbium, a rare earth ion, has unique quantum properties such that it operates in the same band as existing fibre optic networks, eliminating the need for a conversion process. We’ve ...
Entanglement distributed over 1200 km by quantum satellite – Physics World
Quantum satellite: entangled photons have been distributed over 1200 km. Now, a team led by Jian-Wei Pan of the University of Science and Technology of China in Hefei has used the ph...
ATLAS Experiment explores how the Higgs boson interacts with other bosons
Figures 1 and 2: Measurement of the Higgs boson production cross sections in its main production modes and normalised to the Standard Model predictions, as obtained by the H→ZZ→4ℓ an...
What will the future look like? Elon Musk speaks at TED2017
In conversation with TED’s Head Curator Chris Anderson, serial entrepreneur and future-builder Elon Musk discusses his new project digging tunnels under LA, Hyperloop, Tesla, SpaceX ...
Upgrading the CERN LHC’s CMS experiment detector
The CMS experiment is one such detector. But to do this, the CMS detector needed an upgrade. The flexible copper cables emanating from the pixel modules bring the data collected by t...
Understanding the language of cellular communication
This language is thought to be common to many types of cellular communication and has implications for designing future therapies, according to scientists in the laboratory of Michae...
Solar-to-fuel system recycles CO2 to make ethanol and ethylene
Having largely achieved that task using several types of devices, JCAP scientists doing solar-driven carbon dioxide reduction began setting their sights on achieving efficiencies sim...
Scientists evade the Heisenberg uncertainty principle
In MRI, for example, the pointing angle of the spin gives information about where in the body the atom is located, while the amount of spin (the amplitude) is used to distinguish dif...
Quantum computing: towards reality
Now the environment exists to make prototype devices a reality. Enter quantum computers, which were first mooted in the 1980s, when it was suggested that it might be possible to cons...
Physicists find a way to control charged molecules – with quantum logic
The new technique achieves an elusive goal, controlling molecules as effectively as laser cooling and other techniques can control atoms. This type of control of molecular ions – sev...
New materials bring quantum computing closer to reality
Quantum computers work by isolating spinning electrons inside a new type of semiconductor material. Quantum dots One way to create this laser-electron interaction chamber is through...
Five ways quantum computing will change the way we think about computing
In March 2017, IBM announced the industry’s first initiative to build commercially available universal quantum computing systems. One of the first and most promising applications for...
