Quantum non-demolition measurement allows physicists to count photons without destroying them
Physicists propose test for loop quantum gravity
Quantum theory reveals puzzling pattern in how people respond to some surveys
Researchers used quantum theory – usually invoked to describe the actions of subatomic particles – to identify an unexpected and strange pattern in how people respond to survey questions.
How 'spooky' quantum mechanical laws may affect everyday objects (Update)
(PhysOrg.com) -- In a study published in the July 1 issue of the journal Nature, Dartmouth researchers describe one example of the microscopic quantum world influencing--even dominating, they say--the behavi ...
Entanglement between particle and wave-like states of light resembles Schrodinger's cat experiment (Update)
Science's breakthrough of the year: The first quantum machine
Until this year, all human-made objects have moved according to the laws of classical mechanics. Back in March, however, a group of researchers designed a gadget that moves in ways that can only be descri ...
Scientists find quantum mechanics at work in photosynthesis
(PhysOrg.com) -- A team of University of Toronto chemists have made a major contribution to the emerging field of quantum biology, observing quantum mechanics at work in photosynthesis in marine algae.
143 km: Physicists break quantum teleportation distance
Physicists at the University of Vienna and the Austrian Academy of Sciences have achieved quantum teleportation over a record distance of 143 km. The experiment is a major step towards satellite-based quantum ...
Solving big problems with new quantum algorithm
(PhysOrg.com) -- In a recently published paper, Aram Harrow at the University of Bristol and colleagues from MIT in the United States have discovered a quantum algorithm that solves large problems much faster ...
Can an oil bath solve the mysteries of the quantum world?
For the past eight years, two French researchers have been bouncing droplets around a vibrating oil bath and observing their unique behaviour. What sounds like a high-school experiment has in fact provided the first ever ...
Using quantum methods to read classical memories offers surprising advantages
First-ever calculation performed on optical quantum computer chip
(PhysOrg.com) -- A primitive quantum computer that uses single particles of light (photons) whizzing through a silicon chip has performed its first mathematical calculation. This is the first time a calculation ...
Teleportation with engineered quantum systems
A team of University of Queensland physicists has transmitted an atom from one location to another inside an electronic chip.
