Engineers have shown that a widely used method of detecting single photons can also count the presence of at least four photons at a time. The researchers say this discovery will unlock new capabilities in physics labs working in quantum information science around the world, while providing easier paths to developing quantum-based technologies.
UTA and University of Vermont researchers developed an optical medium in which multiple beams of light can autocorrect their properties without affecting other beams. This could lead to a dramatic reduction in the cost and energy consumption of high-speed internet communications.
The emerging domain of parallelized quantum information processing opens up new possibilities for precise measurements, communication and imaging. Precise control of multiple stored photons allows efficient handling of this subtle information in large amounts. In the Quantum Memories Laboratory at Faculty of Physics, University of Warsaw a group of laser-cooled atoms has been used as a memory which can store simultaneously up to 665 quantum states of light. The experimental results have been published in a prestigious Nature Communications journal.
Research teams all over the world are exploring different ways to design a working computing chip that can integrate quantum interactions. Now, Australian and Dutch engineers believe they have cracked the problem, reimagining the silicon microprocessors we know to create a complete design for a quantum computer chip that can be manufactured using mostly standard industry processes and components.
Recently developed computational strategies could help realize the promise of peptide-based drugs. Researchers were able to sample the diverse landscape of shapes that peptides can form as a guide for designing the next generation of stable, potent, selective drugs. They compiled a library of peptide scaffolds upon which drug candidates might be designed. Their methods also can be used to design additional custom peptides with arbitrary shapes on demand.
Presenting their work at this year's Conference on Neural Information Processing Systems, Prof. Josh Tenenbaum and one of his students, Jiajun Wu, are co-authors on four papers that examine the fundamental cognitive abilities that an intelligent agent requires to navigate the world: discerning distinct objects and inferring how they respond to physical forces.
Article describes development of a deep learning neural network to predict disruptions on fusion plasmas.
Brown University researchers have developed software that lets users control robots over the internet with off-the-shelf virtual reality hardware.
The elementary particles of 'new physics' must be so massive that their detection in the LHC, the largest modern accelerator, will not be possible. This none- too-optimistic conclusion comes from the most comprehensive review of observational data from many scientific experiments and their confrontation with several popular varieties of supersymmetry theory. The complicated, extremely computationally demanding analysis was carried out by the team of the international GAMBIT Collaboration -- and leaves a shadow of hope.
Digital screen use is a staple of contemporary life for adults and children, whether they are browsing on laptops and smartphones, or watching TV. Pediatricians and scientists have long expressed concerns about the impact of overusing technology on people's wellbeing. However, new Oxford University research suggests that existing guidance managing children's digital media time may not be as beneficial as first thought.
