A cure for clashing qubits: Researchers successfully entangle different-color photons
Physicists demonstrate a four-fold quantum memory
Researchers at the California Institute of Technology (Caltech) have demonstrated quantum entanglement for a quantum state stored in four spatially distinct atomic memories.
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 ...
Experiment opens the door to multi-party quantum communication (Update)
In the world of quantum science, Alice and Bob have been talking to one another for years. Charlie joined the conversation a few years ago, but now by enforcing the space-like separation of the three parties, ...
Physicists demonstrate quantum entanglement in mechanical system
Physicists at the National Institute of Standards and Technology have demonstrated entanglement--a phenomenon peculiar to the atomic-scale quantum world--in a mechanical system similar to those in the macroscopic ...
Closing the last Bell-test loophole for photons
(Phys.org) —An international team of researchers has reached a milestone in experimental confirmation of a key tenet of quantum mechanics, using ultra-sensitive photon detectors devised by PML scientists.
World first for quantum memory storage
(PhysOrg.com) -- An Australian National University-led team has developed the most efficient quantum memory for light in the world, taking us closer to a future of super-fast computers and communication secured ...
New research signals big future for quantum radar
A prototype quantum radar that has the potential to detect objects which are invisible to conventional systems has been developed by an international research team led by a quantum information scientist at the University ...
An infallible quantum measurement
Entanglement is a key resource for upcoming quantum computers and simulators. Now, physicists in Innsbruck and Geneva realized a new, reliable method to verify entanglement in the laboratory using a minimal ...
The Death of Entanglement: Life Without Half-Life
(PhysOrg.com) -- Quantum entanglement, a type of correlation peculiar to quantum objects, has been found to disregard completely the "half-life" rule that is obeyed by all natural processes, such a radioactive decay.
Researchers show that relatively simple physical systems could yield powerful quantum computers
Quantum computers are devices—still largely theoretical—that could perform certain types of computations much faster than classical computers; one way they might do that is by exploiting "spin," a property ...
Quantum physics: Flavors of entanglement
The entanglement of quantum objects can take surprising forms. Quantum physicists at the University of Innsbruck have investigated several flavors of entanglement in four trapped ions and report their results ...
Scientists provide a new angle on quantum cryptography
An ultra-secure form of coded communication could be given a boost, thanks to scientists from the Universities of Glasgow, Strathclyde and Rochester.
Vibration rocks for entangled diamonds
(PhysOrg.com) -- Diamonds are celebrated for their enduring beauty and hardness but they can also be a physicists best friend.
