A study has turned upside down a typical way of looking at the connection between physics and information in quantum systems — with results that could lead to new insight into quantum computation.
Researchers at NIST have developed a novel way of producing light pulses that are "superluminal"—in some sense they travel faster than the speed of light. The new method could be used to improve the timing of communications signals and to investigate the propagation of quantum correlations.
Researchers have discovered that a process known as spontaneous emission that was previously seen as creating unhelpful noise in quantum data can be harnessed not only to protect the data, but even to compute.
In the age of high-speed computing, the photon is king. However, producing the finely tuned particles of light is a complex and time-consuming process, until now.
Thanks to the work by a team of engineers led by Profe...
Physicists from the University of Zurich have discovered a previously unknown particle composed of three quarks in the Large Hadron Collider (LHC) particle accelerator. A new baryon could thus be detected for the first t...
An international collaboration demonstrates the superiority of a dynamical quantum simulator over state-of-the-art numerical calculations.
Combining known factors in a new way, theoretical physicists Boris Svistunov and Nikolai Prokof’ev at the University of Massachusetts Amherst, with three alumni of their group, have solved an intractable 50-year-old problem: How to simulate strongly interacting quantum systems to allow accurate predictions of their properties.
University of Chicago physicists have experimentally demonstrated for the first time that atoms chilled to temperatures near absolute zero may behave like seemingly unrelated natural systems of vastly different scales
Lancaster University based in the UK is populating part of its new world-class Lancaster Quantum Technology Centre (LQTC) with Oxford Instruments’ plasma systems as part of its strategy for the development of physical sciences.
Researchers at the Universitat Politècnica de València (UPV) and the Universitat Miguel Hernández d'Elx (UMH) have developed a model that provides the basis for the application of commercial photonic c...
Researchers of the Opto-electronic Materials section of the TU Delft and Toyota Europe have demonstrated that several mobile electrons can be produced by the absorption of a single light particle in films of coupled quantum dots.
Macquarie University presented its annual Research Awards at a special awards ceremony held on campus on Wednesday evening. Amongst the award winners was Dr James Rabeau whose team won an award for research into nano diamonds.
A University at Buffalo-led research team has established the presence of a dynamic Jahn-Teller effect in defective diamonds, a finding that will help advance the development of diamond-based systems in applications such as quantum information processing.
Rice University physicists have created a tiny "electron superhighway" that could one day be useful for building a quantum computer, a new type of computer that will use quantum particles in place of the digital transistors found in today's microchips.
For the first time, researchers at the California Institute of Technology (Caltech), in collaboration with a team from the University of Vienna, have managed to cool a miniature mechanical object to its lowest possible energy state using laser light.
