Measurement-based Quantum Compute Leaves Bottlenecks at the Gate
WAKO, Japan, Dec. 27, 2023 — Much of the progress so far in quantum computing has been done on so-called gate-based quantum computers. These devices use physical components, most notably superconducting circuits, to host and control the qubits. The approach bears similarity to conventional, device-based classical computers. The two computing architectures are thus relatively compatible and could be used together in hybrid. Furthermore, future quantum computers could be fabricated by harnessing existing technologies used
Raising Light Frequencies Makes Nanosized Objects Visible
CANBERRA, Australia, May 3, 2023 — Researchers at Australian National University (ANU) and the University of Adelaide are using nanotechnology to increase the frequency of the light that can be detected by cameras and other technologies by up to seven times. There is significant...
Leica Opens Imaging Center in Heidelberg: Week in Brief: 02/04/22
CANBERRA, Australia, Feb. 4, 2022 — Researchers at the Australian National University achieved an efficiency record of 22.6%, breaking their previous record for solar cell efficiency. The study, led by research fellow Jun Peng, focused on 1-cm2 solar cells made with perovskites...
ANU Scientists Set New Record with Bifacial Solar Cells
CANBERRA, Australia, Aug. 31, 2021 — Researchers at Australia National University (ANU) have produced a more efficient type of solar cell — a true bifacial solar cell, using laser processing — and have set a world record for power output with bifacial solar cells in the...
Thin-Film Design Delivers Night-Vision Prototype Without the Bulk
CANBERRA, Australia, June 21, 2021 — An international team of researchers has developed a technology that allows people to see clearly in the dark. The technology is based on nanoscale crystals and has potential applications in defense and safety applications, such as night driving....
Adaptive Optics Keep an Eye on Space Junk
CANBERRA, Australia, May 12, 2021 — Researchers at Australian National University (ANU) have employed an artificial guide star to bring objects orbiting Earth into focus. The approach may help mitigate risks from space debris. The guide star laser is a tool in adaptive optics, a field...
Squeezing Improves LIGO’s Sensitivity to Quantum Noise
CAMBRIDGE, Mass., Dec. 10, 2019 — A new instrument called a quantum vacuum squeezer is helping LIGO — the Laser Interferometer Gravitational-Wave Observatory — to detect gravitational wave signals nearly every week. Just a year ago, LIGO was picking up gravitational...
Miniature Lens Could Enable Fast Transfer of Quantum Information
CANBERRA, Australia, Sept. 17, 2018 — A tiny camera lens, invented by an international research team led by the Australian National University (ANU), could one day be used to link quantum computers to an optical fiber network. The lens is made of a silicon film with millions of...
Infrared Hologram Device Achieves New Optical Properties
CANBERRA, Australia, Jan. 30, 2017 — Australian National University physicists have invented a tiny device that creates the highest quality holographic images ever achieved, opening the door to imaging technologies often seen in science fiction movies. "As a child, I learned about the...
Laser Tractor Beam Operates on Centimeter Scale
CANBERRA, Australia, Oct. 30, 2014 — A new laser tractor beam has the ability to attract and repel millimeter-scale objects over longer distances than previously possible.
Hydrogen Produced Using Photosynthetic Blueprint
CANBERRA, Australia, Aug. 26, 2014 — Researchers have artificially replicated steps of photosynthesis to produce hydrogen as a zero-carbon replacement for petroleum products. A team from Australian National University modified the naturally occurring protein ferritin to display a...
Laser Cooling Enhances Atomic-Force Microscopy
CANBERRA, Australia, Aug. 19, 2014 — Cooling nanowire probes with lasers could lead to significant improvements in the sensitivity and resolution of atomic-force microscopes. The technique, developed by a team from Australian National University, uses lasers to achieve a broadband...
Meta-Atoms Alter Light Polarization
CANBERRA, Australia, July 30, 2014 — A new metamaterial that is deformed by light while altering its polarization could become a tool for developing photonic circuits. A team from Australian National University’s Research School of Physics and Engineering (RSPE) made this new...
Simple Lens-Making Method Turns Phones into Dermascopes
CANBERRA, Austalia, April 25, 2014 — High-resolution silicon polymer lenses can be baked in conventional ovens and attached to smartphones to make an inexpensive microscope.
Lasers to Clean Up Space Junk
CANBERRA, Australia, April 2, 2014 — A new approach to eliminating space debris may be reminiscent of a sci-fi movie scene or video game, but it could actually prove more practical than options previously studied.
Tying knots in light
CANBERRA, Australia – Light can be coaxed to tie itself into knots, but new research suggests that the knot-tying can happen spontaneously – under the right conditions. Australian National University physicists have produced a model from physics and mathematical...
Tying Knots in Light
CANBERRA, Australia, Oct. 31, 2012 — Light can be coaxed to tie itself into knots, but under the right conditions the knot-tying can happen spontaneously, new research suggests.
Surprising Quantum Source Yields Info Advantage
SINGAPORE, Aug. 13, 2012 — Quantum entanglement may not always be necessary to run quantum computers, new research suggests. Moreover, technologies discovered over the past few years can gain a quantum advantage without entanglement.
Laser Systems Model Extreme Events
CANBERRA, Australia, June 19, 2012 — Extreme events in nature may be more commonplace and predictable than you might think, says an international group that uses lasers to study such random events.
Short Movies Stored in Atomic Vapor
COLLEGE PARK, Md., May 31, 2012 — Using lasers and a magnetic field, physicists stored and replayed two letters of the alphabet in a tiny cell of rubidium atoms, the first time two images have been reliably stored in a nonsolid medium.
Expanding Universe Work Earns Trio a Physics Nobel
STOCKHOLM, Oct. 5, 2011 — Competing American astronomers who studied dozens of distant exploding stars, and in the process discovered that the universe is expanding at an ever-accelerating rate, will share the $1.5 million Nobel Prize in Physics for 2011, the Royal Swedish...
Nanowires to Enable Photonic Chip Creation
SWINBURNE, Australia, Oct. 5, 2011 — Using an optimized laser nanofabrication technique, researchers have engineered one of the smallest nanowires made from the optical material chalcogenide glass. The nanowires could lead to the creation of a photonic chip — considered by many...
Coal-rich Australia warms to solar power
Sep 1, 2011 — Australia is a land rich with coal and natural gas – so why is it a boom time for solar energy on the island continent? Coal generates 80 percent of Australia’s electrical energy, and the nation’s coal reserves are so large...
