Imaging Method Lights up Brain Oxygenation
ROCHESTER, N.Y., April 11, 2024 — Researchers at the University of Rochester and University of Copenhagen’s Center for Translational Neuromedicine developed a bioluminescence imaging technique that tracks the movement of oxygen in mice brains to reveal the level of oxygen...
Storage Life Extended for Room-Temperature Qubits
COPENHAGEN, Denmark, June 25, 2021 — Researchers at the University of Copenhagen have demonstrated a method for storing qubits at room temperature for a duration that is hundreds of times longer than has been achieved with previous approaches. The method takes a new approach to the...
Nanochip Team Aims for Quantum Advantage with Photons
COPENHAGEN, Denmark, Dec. 9, 2020 — Collaborating researchers from the University of Copenhagen’s Niels Bohr Institute and the University of Bochum (Germany) have developed a chip with scale-up potential that they say will serve as a core component of a quantum simulator. The...
Photon Connection Helps Researchers Entangle Large, Distant Objects
KØBENHAVN, Denmark, Oct. 12, 2020 — Researchers at the Niels Bohr Institute at the University of Copenhagen have entangled two very different quantum objects — a mechanical oscillator/vibrating dielectric membrane, and a cloud of atoms with each atom acting as a tiny magnet. The...
SMILES Brighten Fluorescent Materials
BLOOMINGTON, Ind., Aug. 11, 2020 — A joint effort between researchers at Indiana University and the University of Copenhagen has yielded a new class of materials, called small-molecule ionic isolation lattices (SMILES), which the researchers say are the brightest fluorescent...
Scientists Show Microwave-Optical Entanglement via Mechanical Interface
COPENHAGEN, April 3, 2020 — Using lasers, researchers at the Niels Bohr Institute at the University of Copenhagen have developed a way to entangle electromagnetic fields from microwave radiation and optical beams. Creating entanglement between microwave and optical fields...
Nanomechanical Router Could Open Way for Scalable Quantum Networks
COPENHAGEN, Denmark, April 29, 2019 — University of Copenhagen researchers have developed a nanocomponent that emits photons carrying quantum information. The component, called a nanomechanical router, emits quantum information carried by photons and routes the photons in different...
Quantum Dots Create Distance Between Electron Spins for Quantum Computing
COPENHAGEN, Denmark, March 21, 2019 — Scientists at the Niels Bohr Institute have realized the swap of electron spins between distant quantum dots. This is significant for future quantum communications because it will allow the distance between the quantum dots to be large enough for...
Hyperspectral Imaging Could Automate, Improve Plastics Recycling
EXTREMADURA, Spain, and COPENHAGEN, Jan. 24, 2019 — A new method using NIR hyperspectral imaging (HSI) and chemometrics could make it possible to sort between different types of plastic and between different flame retardants added to plastic, a necessity for recycling plastics more economically. The...
Scientists Find Way to Overcome Quantum Limit in GWDs
COPENHAGEN, Sept. 7, 2018 — Researchers at the Neils Bohr Institute (NBI) at the University of Copenhagen are developing equipment that will enable gravitational wave detectors (GWDs) to monitor and carry out measurements in an eight times bigger volume of space than what is...
Better Beer, Bread Thanks to Supercontinuum Lasers
Oct 2, 2017 — Most beer is made from four primary ingredients: grains, hops, yeast and water. The basic ingredients for bread are flour, yeast, water and salt. Throw a supercontinuum laser combined with near-IR into the mix and researchers say they can produce...
Commerce, Health and Safety Benefitting From Spectroscopy
Jan 5, 2017 — For decades, spectroscopy has been used in the life sciences, pharmaceuticals, and even cosmetics and forensics applications. Now, researchers are finding new applications for this noninvasive technique in a broad and growing market. New technique...
Research Innovation Recognized by Edmund Educational Awards
BARRINGTON, N.J., Nov. 11, 2015 — Researchers behind a flow cytometer for seawater, a 3D superresolution microscopy technique and the study of bubbles took top honors in this year's Educational Awards presented by Edmund Optics Inc. The awards recognize undergraduate and graduate...
Strain Measurement Optimizes Nanowire LEDs
COPENHAGEN, Denmark, June 30, 2015 — Tiny defects can affect the performance of nanowire LEDs. Now researchers have a way to detect these defects and potentially correct them. A team from the Niels Bohr Institute at the University of Copenhagen used x-ray microscopy to pinpoint exactly...
Narrower Lasers Could Yield Better Atomic Clocks
COPENHAGEN, Denmark, March 10, 2015 — Atomic clocks lose 1 second every 300 million years, but that level of accuracy isn’t good enough for researchers at the Niels Bohr Institute. For even better precision, they’ve devised a new way to narrow the linewidth of the red lasers...
‘Cannon’ Launches Single Photons
COPENHAGEN, Denmark, Sept. 2, 2014 — A new photonic "cannon" could provide the necessary light control for quantum encryption and computing.
Nanowires Could Revolutionize Solar Energy
LAUSANNE, Switzerland, and COPENHAGEN, Denmark, April 9, 2013 — A single nanowire that uses 10,000 times less material can capture 15 times more light and produce energy with incredible efficiency at a much lower cost. The technology could provide the basis for a new generation of highly efficient solar cells or...
Photons can sense each other
COPENHAGEN, Denmark – Photons can “sense” each other and coordinate their separate paths through a complex material, new research from the Niels Bohr Institute shows. The scientists demonstrated that photons emitted from a light source embedded in a complex...
Photons Sense Each Other
COPENHAGEN, Denmark, Dec. 28, 2012 — Photons can “sense” each other and coordinate their separate paths through a complex material, new research from the Niels Bohr Institute shows.
Record Set for Cesium Atom Entanglement
COPENHAGEN, Denmark, Aug. 22, 2011 — A record for maintaining the entanglement of the spins of two gas clouds of cesium atoms for up to an hour has been set by researchers from Niels Bohr Institute (NBI) at the University of Copenhagen. Entanglement, a key component in quantum...
Entangled Light Beams Store Quantum Info
COPENHAGEN, Denmark, Nov. 10, 2010 — Quantum information has been stored using two entangled light beams, researchers at the Niels Bohr Institute at the University of Cophenhagen report. Quantum memory or information storage is a necessary element of future quantum communication...
Photon-Powered PCs Proposed
COPENHAGEN, Denmark, Aug. 27, 2007 -- A new theory uses nonlinear optics to create the photon transistors necessary to drive future quantum computers. Incredibly fast supercomputers that can solve extremely complicated tasks have long been a dream for researchers, but there are some...
