Making Quantum Connections

In quantum mechanics, interactions between particles can give rise to entanglement, which is a strange type of connection that could never be described by a non-quantum, classical theory. These connections, called quantum correlations, are present in entangled systems even if the objects are not physically linked (with wires, for example). Entanglement is at the heart of what distinguishes purely quantum systems from classical ones; it is why they are potentially useful, but it sometimes makes them very difficult to understand.

JQI welcomes new Fellow Mohammad Hafezi

Mohammad Hafezi has accepted a position as a JQI Fellow and Assistant Professor in UMD's Electrical and Computer Engineering Department. He started at JQI in 2009 in Jake Taylor's group as a postdoc and was promoted to senior research associate in 2012. He works at the interface of condensed matter theory and quantum optics. The focus of his research is on theoretical and experimental investigations of artificial gauge fields and topological order in photonics systems. Such systems can be exploited as robust optical devices insensitive to disorder.

How do you build a large-scale quantum computer?

Physicists led by ion-trapper Christopher Monroe at the JQI have proposed a modular quantum computer architecture that promises scalability to much larger numbers of qubits. The components of this architecture have individually been tested and are available, making it a promising approach. In the paper, the authors present expected performance and scaling calculations, demonstrating that their architecture is not only viable, but in some ways, preferable when compared to related schemes.

Stirring-up atomtronics in a quantum circuit

Atomtronics is an emerging technology whereby physicists use ensembles of atoms to build analogs to electronic circuit elements. Modern electronics relies on utilizing the charge properties of the electron. Using lasers and magnetic fields, atomic systems can be engineered to have behavior analogous to that of electrons, making them an exciting platform for studying and generating alternatives to charge-based electronics.

Making Color

Can scientists generate any color of light? The answer is not really, but the invention of the laser in 1960 opened new doors for this endeavor. In a result published in Nature Communications scientists* demonstrate a new semiconductor microstructure that performs frequency conversion. This design is a factor of 1000 smaller than previous devices.
