Los Alamos reveals it's been running quantum network for two and a half years
Does the quantum wave function represent reality?
Quantum computing may actually be useful, after all
(PhysOrg.com) -- In recent years, quantum computers have lost some of their luster. In the 1990s, it seemed that they might be able to solve a class of difficult but common problems — the so-called NP-complete ...
Quantum non-demolition measurement allows physicists to count photons without destroying them
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 ...
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 ...
Physicists Solve Difficult Classical Problem with One Quantum Bit
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 ...
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.
Physicists propose test for loop quantum gravity
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
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.
