Physicists propose test for loop quantum gravity
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 ...
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 ...
Space-based experiment could test gravity's effects on quantum entanglement
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.
The diamond’s quantum memory
For years, quantum computers have been the holy grail of quantum technology. When a normal computer has to solve a number of problems, it can only execute them one after the other. In contrast, a quantum computer ...
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 ...
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.
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 ...
Not all quantum properties are lost through interaction with the environment
Quantum engineering pushes refrigerator beyond classical efficiency limits
Physicists Propose New Method for Quantum Computing
(PhysOrg.com) -- The new system, which can compute faster and more efficiently than previous quantum computers, may bring the technology closer to reality.
