Researchers implement 3-qubit Grover search on a quantum computer
Searching large, unordered databases for a desired item is a time-consuming task for classical computers, but quantum computers are expected to perform these searches much more quickly.
'Quantum radio' may aid communications and mapping indoors, underground and underwater
Researchers at the National Institute of Standards and Technology (NIST) have demonstrated that quantum physics might enable communications and mapping in locations where GPS and ordinary cellphones and radios don't work reliably or even at all, such as indoors, in urban canyons, underwater and underground.
High-speed quantum encryption may help secure the future Internet
Recent advances in quantum computers may soon give hackers access to machines powerful enough to crack even the toughest of standard internet security codes.
New quantum computer chip uses sounds waves to store data
Scientists have designed a new quantum computer chip that uses sound waves to store and convert quantum data.
New quantum memory device small enough to fit on a chip (Video)
A team of researchers from the US and Italy built a quantum memory device that is approximately 1,000 times smaller than similar devices — small enough to install on a chip.
Physicists make quantum leap in understanding life's nanoscale machinery
A diagnostic technique that can detect tiny molecules signaling the presence of cancer could be on the horizon.
Quantum tractor beam could tug atoms, molecules
The wavelike properties of quantum matter could lead to a scaled-down version of Star Trek technology.
Protecting quantum computing networks against hacking threats
Protecting traditional computer systems, which use zeros and ones, from hackers is not a perfect science.
Quantum computing breakthrough could help 'change life completely'
Scientists claim to have produced the first-ever blueprint for a large-scale quantum computer in a development that could bring about a technological revolution on a par with the invention of computing itself.
Electron-photon small-talk could have big impact on quantum computing
In a step that brings silicon-based quantum computers closer to reality, researchers at Princeton University have built a device in which a single electron can pass its quantum information to a particle of light. The particle of light, or photon, can then act as a messenger to carry the information to other electrons, creating connections that form the circuits of a quantum computer.
Quantum computing a step closer to reality
Physicists at the Australian National University (ANU) have brought quantum computing a step closer to reality by stopping light in a new experiment.
Scientists teleport quantum information across four-mile cable
A pair of research teams — one in Canada and one in China — just showcased quantum teleportation across four-mile cables. The feat promises to pave the way for a quantum internet.
Quantum effects observed in 'one-dimensional' wires
Researchers have observed quantum effects in electrons by squeezing them into one-dimensional 'quantum wires' and observing the interactions between them. The results could be used to aid in the development of quantum technologies, including quantum computing.
Quantum fragility may help birds navigate
Harnessing the weirdness of the quantum world is difficult — fragile quantum properties quickly degrade under typical conditions. But such fragility could help migrating birds find their way, scientists report in the June New Journal of Physics.
Quantum weirdness survives space travel
In a feat that demonstrates the feasibility of using satellites to transmit uncrackable quantum messages, scientists have measured the quantum properties of photons sent to space and back again.
