Apparent roadblock in the development of quantum lithography
Researchers convert quantum signals to telecom wavelengths, increase memory times
Using optically dense, ultra-cold clouds of rubidium atoms, researchers have made advances in three key elements needed for quantum information systems - including a technique for converting photons carrying ...
Scientists provide a new angle on quantum cryptography
An ultra-secure form of coded communication could be given a boost, thanks to scientists from the Universities of Glasgow, Strathclyde and Rochester.
A new ultrabright source of entangled photon pairs
At the very heart of applications such as quantum cryptography, computation and teleportation lies a fascinating phenomenon known as "entanglement". Two photons are entangled if the properties of one depend ...

Using degrees of freedom to get hyperentanglement
A solid case of entanglement
Physicists have finally managed to demonstrate quantum entanglement of spatially separated electrons in solid state circuitry.
JQI researchers create entangled photons from quantum dots
To exploit the quantum world to the fullest, a key commodity is entanglement—the spooky, distance-defying link that can form between objects such as atoms even when they are completely shielded from one another. Now, physicists ...
Creating a six-qubit cluster state
Building a better qubit: Combining 6 photons together results in highly robust qubits
Exploiting quantum mechanics for transmitting information is a tantalizing possibility because it promises secure, high speed communications. Unfortunately, the fragility of methods for storing and sending ...
Physicists Explain How Human Eyes Can Detect Quantum Effects
New method to detect quantum mechanical effects in ordinary objects
At the quantum level, the atoms that make up matter and the photons that make up light behave in a number of seemingly bizarre ways. Particles can exist in "superposition," in more than one state at the same ...
