Store Single Photons in a Vapor Cell and Pass Them on Later? Yes, U. Basel Scientists Show
U. Basel researchers have realized a single photon source which allowed them to test the quality and storage time of quantum memory.
Twin Photons From Unequal Sources?
A team of researchers led by Richard Warburton at the University of Basel, in collaboration with colleagues at the University of Bochum, has now succeeded in creating identical photons originating from different and widely-separated sources.
Using Quantum Computing to Understand Quantum Systems
Part of the work of the TQN – Theory of Quantum Nanostructures, and many other groups worldwide, is to model quantum systems using conventional computers to crack down the equations.
Seismic Sensing Using Quantum Cryptography Network
Experiment demonstrates that quantum key distribution networks, which are part of highly secure cryptography schemes, can also detect and locate earthquakes.
New Error Mitigation Approach Helps Quantum Computers Quiet Their Act
Researchers at Lawrence Berkeley National Laboratory developed a new approach to quantum error mitigation that could help make quantum computing’s theoretical potential a reality: noise estimation circuits.
Derived and Verified for the 1st Time: Information Preservation Relation in Quantum Measurement
Quantum superposition and measurement are not only the foundation of quantum physics, but also guarantee the safety of quantum computing and cryptography. The KIST research team derived and verified the information preservation relation for the first time in quantum measurement.
How to Create Magnetic Skyrmions in Ultra-Short Time Scales Using Pulses of Laser Light
In a new study, researchers Claudio Verdozzi from Lund University and Emil Viñas Boström and Angel Rubio from the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg have found a new approach. “In our study, we have theoretically shown how it is possible to meet one of these requirements, that is, how to create magnetic skyrmions in ultra-short time scales using pulses of laser light”, says Claudio Verdozzi, physics researcher at Lund University.
Stony Brook U Discovery Provides Novel Platform for the Second Quantum Revolution
The development of experimental platforms that advance the field of quantum science and technology (QIST) comes with a unique set of advantages and challenges common to any emergent technology. Researchers at Stony Brook University, led by Dominik Schneble, PhD, report the formation of matter-wave polaritons in an optical lattice, an experimental discovery that enables studies of a central QIST paradigm through direct quantum simulation using ultracold atoms. The researchers project that their novel quasiparticles, which mimic strongly interacting photons in materials and devices but circumvent some of the inherent challenges, will benefit the further development of QIST platforms that are poised to transform computing and communication technology.
