When memory qubits and photons get entangled
Encrypting data in a way that ensures secure communication is an ever-growing challenge because crucial components of today's encryption systems cannot withstand future quantum computers. Researchers around the world are therefore working on technolo.....»»
Neutral atom innovations by quantum systems accelerator mark quantum computing milestones
Before quantum computers can solve complex problems, researchers must develop technologies that manage larger numbers of qubits (the building blocks of quantum computers) for extended periods. Neutral atoms play an important role in this effort and a.....»»
Licking an ice lolly at school might make a good memory, but this isn"t the secret to learning science
A group of scientists, including people from the Royal Society of Chemistry, recently proposed that experiences such as licking an ice lolly should be part of the science curriculum. By licking a lolly and seeing how it melts—the idea goes—childr.....»»
Entangled photon pairs enable hidden image encoding
Researchers at the Paris Institute of Nanoscience at Sorbonne University have developed a new method to encode images into the quantum correlations of photon pairs, making it invisible to conventional imaging techniques. The study is published in the.....»»
Researchers say 40% of UK seabird species are in trouble—bird flu, climate change, overfishing to blame
A visit to a seabird colony in summer is an assault on the senses. First there's the noise, then the overwhelming ammonia smell that stains the memory, and then the swirl of color and activity on the white-washed cliffs......»»
Researchers create entangled quantum magnets with protected quantum excitations
When different quantum states combine, new collective states of matter can emerge. In the quantum realm, combining components such as atoms that possess quantum effects can give rise to macroscopic quantum states of matter, featuring exotic quantum e.....»»
Scientists create ultracompact polarization-entangled photon sources for miniaturized quantum devices
Scientists have created an ultra-thin light source that emits pairs of polarization-entangled photons. These specially correlated photons hold promise for future quantum technologies, including ultra-secure communication, powerful computation, and hi.....»»
The FBI is apparently not great at keeping its own memory systems secure
The FBI has been criticized for the way it handles storage and destruction of data hardware......»»
Physicists ease path to entanglement for quantum sensing
Nothing in science can be achieved or understood without measurement. Today, thanks to advances in quantum sensing, scientists can measure things that were once impossible to even imagine: vibrations of atoms, properties of individual photons, fluctu.....»»
Test of a prototype quantum internet runs under New York City for half a month
To introduce quantum networks into the marketplace, engineers must overcome the fragility of entangled states in a fiber cable and ensure the efficiency of signal delivery. Now, scientists at Qunnect Inc. in Brooklyn, New York, have taken a large ste.....»»
Researcher explores how you can stretch your mind to grasp quantum entanglement
My new article, "Quantum Entanglement of Optical Photons: The First Experiment, 1964–67," is intended to convey the spirit of a small research project that reaches into uncharted territory. The article breaks with tradition, as it offers a first-pe.....»»
Humpback whale freed from Sydney Harbour after 22-hour ordeal
A juvenile humpback whale was freed Friday after it was entangled in ropes and buoys in the harbour of Australia's largest city for 22 hours......»»
Study uncovers condensed-matter dark states in a quantum system with two pairs of sublattices
Dark states are quantum states in which a system does not interact with external fields, such as light (i.e., photons) or electromagnetic fields. These states, which generally occur due to interferences between the pathways through which a system int.....»»
A maximally entangled quantum state with a fixed spectrum does not exist in the presence of noise, mathematician claims
For more than 20 years, quantum researchers have wondered whether a quantum system can have maximum entanglement in the presence of noise. A mathematician from Spain recently answered the question: No......»»

Ultrathin quantum light sources: Scientists show excitonic interactions boost efficiency of entangled photon generation
Scientists from the National University of Singapore (NUS) have shown that excitonic resonances and transitions between excitons can significantly increase the efficiency of generating entangled photon pairs. This could lead to the development of eff.....»»
How long do SSDs really last?
Samsung If you want fast and reliable storage, there’s no question — you should get a , and if you , it might serve you well for years. However, by definition, SSDs don’t last forever. The NAND flash memory that powers them only has.....»»
Theoretical research holds promise for advancing modular quantum information processing
The operation of a quantum computer relies on encoding and processing information in the form of quantum bits—defined by two states of quantum systems such as electrons and photons. Unlike binary bits used in classical computers, quantum bits can e.....»»
Singing from memory unlocks a surprisingly common musical superpower
Psychologists from UC Santa Cruz wanted to study "earworms," the types of songs that get stuck in your head and play automatically on a loop. So they asked people to sing out any earworms they were experiencing and record them on their phones when pr.....»»
Waste into gold: Oyster shells repurposed as magic "Seawool"
Growing up on Taiwan's west coast where mollusk farming is popular, Eddie Wang saw discarded oyster shells transformed from waste to function—a memory that inspired him to create a unique and environmentally friendly fabric called "Seawool"......»»
