NSA May be Attempting to Exploit Practical Loops in Quantum Key Distribution

In this month's issue of Physics World, Jon Cartwright explains how the revelation that the US National Security Agency (NSA) is developing quantum computers has renewed interest and sparked debate on just how far ahead they are of the world's major labs looking to develop the same technology.

Researchers Manipulate Photons on Silicon Chip, Make Significant Progress Towards Quantum Computer

An international research group of scientists and engineers led by the University of Bristol, UK, has made an important advance towards a quantum computer by shrinking down key components and integrating them onto a silicon microchip.

Potentially Harder Tests Needed for Quantifying Quantum Speedup

Texas A&M University physicist Helmut G. Katzgraber's research takes him to the crossroads of physics, computer science, quantum information theory and statistical mechanics. For more than a decade, he has been pushing the frontiers of computational physics to study hard optimization problems and disordered materials, applying his expertise to problems in the fascinating and fast-evolving field of quantum computing.

Novel Nanoscale Sensitive Quantum Measurement Device Operates at Wider Range of Temperatures

Nanoscale Superconducting QUantum Interference Devices (nanoSQUIDs) are potentially the most sensitive measurement devices in the world. They detect changes in an electromagnetic property known as magnetic flux, which means they can be used to detect single photons or to characterise the tiny quantum oscillations in nano-electromechanical systems (NEMS).

Quantum Physics-Based ‘One-Shot’ Memory Unit Could Boost Computer Security Systems

Computer security systems may one day get a boost from quantum physics, as a result of recent research from the National Institute of Standards and Technology (NIST). Computer scientist Yi-Kai Liu has devised away to make a security device that has proved notoriously difficult to build—a "one-shot" memory unit, whose contents can be read only a single time.

Novel Method to Cool Trapped Ions and Put Them into Entangled States

In Manas Mukherjee's laboratory at CQT, they have only recently trapped their first cloud of ions, but they've already got ambitious plans for what to do with them. Manas and his collaborators have proposed a novel way to cool trapped ions and put them into an entangled state. Such states can form the starting point for quantum computations or simulations. The work was published in Physical Review Letters in October.

New Lab for Creation of Quantum Materials Opens at Institute for Quantum Computing

A first-of-its-kind, world-class laboratory that could lead to the creation of quantum materials for use in a new generation of technologies opened at the University of Waterloo’s Institute for Quantum Computing (IQC) today.

Time Travelers Could Possibly Copy Quantum Data from the Past

Popular television shows such as "Doctor Who" have brought the idea of time travel into the vernacular of popular culture. But problem of time travel is even more complicated than one might think. LSU's Mark Wilde has shown that it would theoretically be possible for time travelers to copy quantum data from the past.

Nonlinear Light-Generating Zero-Index Metamaterial Holds Promise for Quantum Computing

The Information Age will get a major upgrade with the arrival of quantum processors many times faster and more powerful than today's supercomputers.

Photon Pairs Produced Through Four-Wave Mixing in Cold Atomic Vapour

Quantum technologies for communication and computation can play on the strengths of different systems: photons are good for zipping information around, atoms are good for storage. CQT researchers have demonstrated a technique for producing entangled photon pairs that promises to help interface the two.
