Engineers make sound loud enough to bend light on a computer chip
During a thunderstorm, we all know that it is common to hear thunder after we see the lightning. That's because sound travels much slower (768 miles per hour) than light (670,000,000 miles per hour).
Three's a charm: NIST detectors reveal entangled photon triplets
Researchers at the University of Waterloo in Canada have directly entangled three photons in the most technologically useful state for the first time, thanks in part to superfast, super-efficient single-photon ...
Quantum biology: Algae evolved to switch quantum coherence on and off
A UNSW Australia-led team of researchers has discovered how algae that survive in very low levels of light are able to switch on and off a weird quantum phenomenon that occurs during photosynthesis.
Rare earth ions in a crystal become candidate for a quantum memory
(Phys.org) —A promising material is lining itself up as a candidate for a quantum memory. A team at the Max Planck Institute for the Science of Light in Erlangen is the first to succeed in performing high-resolution ...
How to test the twin paradox without using a spaceship
Forget about anti-ageing creams and hair treatments. If you want to stay young, get a fast spaceship. That is what Einstein's Theory of Relativity predicted a century ago, and it is commonly known as "twin ...
Ultrabright lasers help switch single photons
(Phys.org) —In the search for a single photon source, researchers in Australia and France have achieved a major step towards a turn-key source of individual, precisely tailored photons from an integrated ...
Proposed modular quantum computer architecture offers scalability to large numbers of qubits
How do you build a universal quantum computer? Turns out, this question was addressed by theoretical physicists about 15 years ago. The answer was laid out in a research paper and has become known as the ...
Quantum mechanics explains efficiency of photosynthesis
Light-gathering macromolecules in plant cells transfer energy by taking advantage of molecular vibrations whose physical descriptions have no equivalents in classical physics, according to the first unambiguous ...
Distant artificial atoms cooperate by sharing light, physicists show
An international team of scientists has shown for the first time that atoms can work collectively rather than independently of each other to share light.
Simulation sets atoms shivering
(Phys.org) —In "Harry Potter and the Sorcerer's Stone" (JK Rowling, 1997), Harry, Ron, and Hermione encounter a massive stone chessboard, one of many obstacles in their path. To advance, they must play, ...
Beyond quantum simulation: Physicists create 'crystal' of spin-swapping ultracold molecules
Physicists at JILA have created a crystal-like arrangement of ultracold gas molecules that can swap quantum "spin" properties with nearby and distant partners. The novel structure might be used to simulate ...
Physicist disentangles 'Schrodinger's cat' debate
Physicist Art Hobson has offered a solution, within the framework of standard quantum physics, to the long-running debate about the nature of quantum measurement.
'Listening' to black holes form with gravity waves
New technology that breaks the quantum measurement barrier has been developed to detect the gravity waves first predicted by Einstein in 1916.
Physicists discover atomic clock can simulate quantum magnetism
Researchers at JILA have for the first time used an atomic clock as a quantum simulator, mimicking the behavior of a different, more complex quantum system.
