Physicists 'teleport' logic operation between separated ions

Physicists at the National Institute of Standards and Technology (NIST) have teleported a computer circuit instruction known as a quantum logic operation between two separated ions (electrically charged atoms), showcasing ...

New blueprint for more stable quantum computers

Researchers at the Paul Scherrer Institute (PSI) have put forward a detailed plan of how faster and better defined quantum bits—qubits—can be created. The central elements are magnetic atoms from the class of so-called ...

Paving the way for a faster quantum computer

A team of physicists from the University of Vienna and the Austrian Academy of Sciences have demonstrated a new quantum computation scheme in which operations occur without a well-defined order. The researchers led by Philip ...

Ions clear another hurdle toward scaled-up quantum computing

Scientists at the Joint Quantum Institute (JQI) have been steadily improving the performance of ion trap systems, a leading platform for future quantum computers. Now, a team of researchers led by JQI Fellows Norbert Linke ...

Early look at Windows 8 baffles consumers (Update)

The release of Microsoft's Windows 8 operating system is a week away, and consumers are in for a shock. Windows, used in one form or another for a generation, is getting a completely different look that will force users to ...

First Google hire leaving for online academy

The first person hired by Google's founders is leaving the Internet giant to devote himself to an innovative online education website called Khan Academy.

Counting photons for quantum computing

Experts in nuclear physics and quantum information have demonstrated the application of a photon-number-resolving system to accurately resolve more than 100 photons. The feat is a major step forward in capability for quantum ...

Full control of a six-qubit quantum processor in silicon

Researchers at QuTech—a collaboration between the Delft University of Technology and TNO—have engineered a record number of six, silicon-based, spin qubits in a fully interoperable array. Importantly, the qubits can be ...
