Research Bits: June 8

Five-second coherence for silicon carbide qubits Researchers from the University of Chicago, National Institutes for Quantum Science and Technology, and Linköping University built a qubit from silicon carbide and was able to retain its coherence, or the length of time the quantum state persists, for over five seconds. “It’s uncommon to have quantum information preserved on these human ... » read more

Step Towards Quantum Internet: Quantum Teleportation (TU Delft)

New research paper "Qubit teleportation between non-neighbouring nodes in a quantum network" from QuTech and Kavli Institute of Nanoscience, Delft University of Technology, Delft, The Netherlands. Abstract "Future quantum internet applications will derive their power from the ability to share quantum information across the network. Quantum teleportation allows for the reliable transfer of q... » read more

Bell state analyzer for spectrally distinct photons

Abstract "We demonstrate a Bell state analyzer that operates directly on frequency mismatch. Based on electro-optic modulators and Fourier-transform pulse shapers, our quantum frequency processor design implements interleaved Hadamard gates in discrete frequency modes. Experimental tests on entangled-photon inputs reveal fidelities of ∼98% for discriminating between the |Ψ+⟩ and |Ψ−⟩... » read more

Manufacturing Bits: Aug. 18

Quantum Internet The U.S. Department of Energy (DOE) recently unveiled a strategy to develop a quantum Internet in the United States. DOE’s 17 National Laboratories will serve as the backbone of the quantum Internet, which will rely on the laws of quantum mechanics to control and transmit information over a network. Currently in its initial stages of development, the quantum Internet coul... » read more

System Bits: Oct. 1

Jumping the gap in microchips A quasi-particle that travels along the interface of a metal and dielectric material may be the solution to problems caused by shrinking electronic components, according to an international team of engineers. "Microelectronic chips are ubiquitous today," said Akhlesh Lakhtakia, Evan Pugh University Professor and Charles Godfrey Binder Professor of Engineering S... » read more

Power/Performance Bits: Feb. 19

Flexible energy harvesting rectenna Researchers from MIT, Universidad Politécnica de Madrid, University Carlos III of Madrid, Boston University, University of Southern California, and the Army Research Laboratory created a flexible rectenna capable of converting energy from Wi-Fi signals into electricity to power small devices and sensors. The device uses a flexible RF antenna to capture e... » read more
