Scientists cast doubt on renowned uncertainty principle
Werner Heisenberg's uncertainty principle, formulated by the theoretical physicist in 1927, is one of the cornerstones of quantum mechanics. In its most familiar form, it says that it is impossible to measure ...
67-attosecond extreme ultraviolet laser pulse is the world's shortest
A University of Central Florida research team has created the world's shortest laser pulse and in the process may have given scientists a new tool to watch quantum mechanics in action – something that has ...
A one-way street for spinning atoms
Elementary particles have a property called "spin" that can be thought of as rotation around their axes. In work reported this week in the journal Physical Review Letters, MIT physicists have imposed a stri ...
Shaking the electron has strengthened quantum mechanics
Decays of atomic nuclei are potential sources of information on fundamental phenomena occurring in the quantum world. Unfortunately, it is a rather difficult task to model such processes. However, NCBJ physicists ...
Nature: Electronic read-out of quantum bits
Quantum computers promise to reach computation speeds far beyond that of today's computers. As they would use quantum effects, however, they would also be susceptible to external interferences. Information ...
Caught on camera: quantum mechanics in action
(Phys.org) -- Scientists at the University of Glasgow have captured images of ‘quantum entanglement’ on camera for the first time.
Electromagnetic 'swamps' don't always bog electrons down
Scientists have designed a simple system to study how electrons travel through energy barriers instead of over them.
A roll of the dice: Quantum mechanics researchers show that nature is unpredictable
Many of the predictions we make in everyday life are vague, and we often get them wrong because we have incomplete information, such as when we predict the weather.
Classical problem becomes undecidable in a quantum setting
Entanglement study makes a quantum leap
Some scientists have likened it to voodoo, while Albert Einstein called it just plain "spooky." In the bizarre realm of quantum mechanics, entanglement is the phenomenon in which two seemingly distinct particles control each ...
Strength in numbers: Physicists identify new quantum state allowing three -- but not two -- atoms to stick together
(Phys.org) -- A Kansas State University-led quantum mechanics study has discovered a new bound state in atoms that may help scientists better understand matter and its composition.
Researchers tune the strain in graphene drumheads to create quantum dots
Researchers have shown that they can tune the strain in graphene suspended like drumheads over microscopic holes in a substrate of silicon oxide using the tip of an advanced scanning probe microscope and a ...
Quantum bar magnets in a transparent salt
Scientists have managed to switch on and off the magnetism of a new material using quantum mechanics, making the material a test bed for future quantum devices.
Got mass? Scientists observe electrons become both heavy and speedy
A Princeton University-led team of scientists has shown how electrons moving in certain solids can behave as though they are a thousand times more massive than free electrons, yet at the same time act as speedy ...
