Putting Entanglement on Hold

A JQI team has shown that entanglement -- the quantum-mechanical process by which the properties of two objects become inextricably intertwined -- persists between two complex images even when one of them is slowed down by a factor of 500. Read More

The Quantum Wire

  • Quantum Encrypted Information Sent Over An Eight-Node, Mesh Network
    Science Daily -- Researchers from across Europe have united to build the largest quantum key distribution network ever built. The efforts of 41 research and industrial organisations were realised as secure, quantum encrypted information was sent over an eight node, mesh network.
  • Coherent Holes in a Semiconductor Quantum Dot
    Science -- Perspective: Quantum states of positive charge carriers may be more stable to information loss than those of electron-based systems. [PDF]
  • Photons pushed together
    Nature -- News & Views: Photons do not interact well with each other, which is a real headache for researchers developing all-optical transistors for computing applications. But a single molecule can mediate photon–photon affairs. [PDF]
  • Quantum Communications One Step Closer: Novel Ion Trap
    Science Daily -- A novel ion trap geometry demonstrated at NIST could usher in a new generation of applications. The device holds promise as a stylus for sensing very small forces or as an interface for efficient transfer of individual light particles for quantum communications.
  • Quasiparticle doppelgängers
    Physics -- Viewpoint: By exploiting the concept of particle-hole duality, one can realize a point junction between integer and fractional quantum Hall phases, which constitutes a crucial building block towards possible applications of the quantum Hall effect.
  • Scientists create first electronic quantum processor
    EurekAlert -- They also used the two-qubit superconducting chip to successfully run elementary algorithms, such as a simple search, demonstrating quantum information processing with a solid-state device for the first time. The findings appear in Nature's advance online publication June 28.
  • Lasers Can Lengthen Quantum Bit Memory By 1,000 Times
    ScienceDaily -- Physicists have found a way to drastically prolong the shelf life of quantum bits, the 0s and 1s of quantum computers.
  • Super resolution with superposition
    Physics -- Viewpoint: A proposal for obtaining optical resolution better than the classical limit by means of spatially entangled quantum states of light opens a new frontier in the fields of quantum optical imaging, metrology, and sensing.
