Recently, a new Dirac material - a lattice system where the excitations are described by relativistic Dirac or Weyl equations - namely a topological insulator (TI), entered researchers' sight. TIs possess a small band gap in their bulk state and a gapless metallic state at their edge/surface. A research group working on two-dimensional materials photonicshas now experimentally demonstrated for the first time tha ...

When it comes to recognizing complex patterns or to decoding encrypted messages, conventional computers reach their limits. A whole new quality in the communication and processing of data is expected from a technology that exploits the special properties of quantum particles such as superposition and entanglement. Scientists are pursuing a variety of different concepts towards the development of such a quantum computer. One professor follows the strategy o ...

KentuckyFC (1144503) writes "The resolving power of telescopes is limited by the diffraction limit, a natural bound on resolution caused by the way light diffracts as it passes through a lens. But in recent years, physicists have worked out how to use quantum techniques to beat the diffraction limit. The trick is to create a pair of entangled photons, use one to illuminate the target and the other to increase the ...

March Du Nain Rouge
One approach to make qubits for quantum computing relies on the creation of two single photons that interfere with one another in a device called a waveguide. Results from a recent applied science study support the idea that waveguides coupled with another quantum particle -- the surface plasmon -- co ...

Quantum photon properties revealed in another particle—the plasmon


March Du Nain Rouge
( —For years, researchers have been interested in developing quantum computers—the theoretical next generation of technology that will outperform conventional computers. Instead of holding data in bits, the digital units used by computers today, quantum computers store information in units called "qubits." One approach for computing with qubits relies on the creation of two single photons that interfere with one another in a device called a ...
