Researchers in Quantum Engineering Explore both Basic and Applied Research

It can be difficult to distinguish between basic and applied research in the nascent field of quantum engineering. One person’s exploration of quantum systems like atoms and electrons yields another’s building block for quantum computers, and vice versa.

Hydrogen-Treated Fibers May Help Reduce Errors in Quantum Computing

To make a better optical fiber for transmitting laser beams, the first idea that comes to mind is probably not a nice long hydrogen bath.

Robust Approach to Certify Quantum Devices

An international team including CQT researchers has come up with a "robust and versatile" scheme for doing quality testing of quantum devices. The scheme is described in a 22 July paper in Physical Review Letters.

Diamonds and Nitrogen Atoms Could be Assembled to Create Topologically Protected Quantum Computer

The Quantum Computer is the Holy Grail of quantum technology. Its computing power would eclipse even the fastest classical computers we have today. A team of researchers from TU Wien (Vienna) the National Institute for Informatics (Tokyo) and NTT Basic Research Labs in Japan has now proposed a new architecture for quantum computing, based on microscopic defects in diamond.

Controlled Positioning of Atomic-Scale Diamond Defects May Help Build Better Quantum Computers

By carefully controlling the position of an atomic-scale diamond defect within a volume smaller than what some viruses would fill, researchers have cleared a path toward better quantum computers and nanoscale sensors. They describe their technique in a paper published in the journal Applied Physics Letters, from AIP Publishing.

Quantum Entanglement of Particles Preserved When Passing Through an Amplifier

Physicists Sergei Filippov (MIPT and Russian Quantum Center at Skolkovo) and Mario Ziman (Masaryk University in Brno, Czech Republic, and the Institute of Physics in Bratislava, Slovakia) have found a way to preserve quantum entanglement of particles passing through an amplifier and, conversely, when transmitting a signal over long distances. Details are provided in an article published in the journal Physical Review A (see preprint).
