Squeezed Light Improves Accuracy of Magnetometry Measurements
BARCELONA, Spain, Nov. 22, 2021 — Researchers from ICFO (The Institute of Photonic Sciences) and Hangzhou Dianzi University have revealed that the effect known as “squeezed light” — the organization of photons in motion that ensures that they arrive on a target in...
Xanadu, Imec Partner to Develop Quantum Photonic Chips
TORONTO, Aug. 19, 2021 — Xanadu, a full-stack photonic quantum computing company, and imec are partnering to develop the next generation of quantum qubits based on ultralow-loss silicon nitride waveguides. A SiN wafer with photonic integrated circuits manufactured on...
Researchers Claim New Record in Quantum Light Detection
BRISTOL, England, Nov. 12, 2020 — Researchers from the University of Bristol have claimed a new record for detecting squeezed light, using a newly developed balanced homodyne detector. The work could pave the way for higher-performance quantum computers and quantum communications....
Quantum Microscope Squeezes Out Noise
OAK RIDGE, Tenn., Sept. 16, 2020 — Researchers at the U.S. Department of Energy’s Oak Ridge National Laboratory (ORNL) used quantum optics to advance state-of-the-art microscopy and, in doing so, chart a a path to detecting material properties with greater sensitivity than is...
Photonic Cluster States Generated at Room Temps for Quantum Computation
KONGENS LYNGBY, Denmark, Nov. 18, 2019 — To observe quantum phenomena on a macroscopic scale, researchers at the Center for Macroscopic Quantum States (bigQ) and the Technical University of Denmark (DTU) created an extremely entangled quantum state, called a cluster state. The team’s...
Optical Quantum Processor Scales to Extreme
MELBOURNE, Australia, Oct. 29, 2019 — A prototype of a large-scale quantum processor made of laser light has been created by a team from Australia, Japan, and the U.S. The processor has built-in scalability that allows the number of quantum components to scale to extreme numbers. “Our...
Squeezed Light Reduces Noise, Could Speed Quantum Sensing
OAK RIDGE, Tenn., June 20, 2019 — Oak Ridge National Laboratory (ORNL) physicists studying quantum sensing, which could affect a range of potential applications from airport security scanning to gravitational wave measurements, said that certain quantum sensors can use a...
Directional Character of Nanolight Could Improve Efficiency of Nanophotonic Devices
MELBOURNE, Australia, Oct. 26, 2018 — Squeezed light in the nanoscale (“nanolight”) was found to propagate only in specific directions along thin slabs of molybdenum trioxide (α-MoO3), a natural anisotropic 2D material. The discovery was made by an international team...
Squeezing Light Cools Microscopic Drum Below Quantum Limit
GAITHERSBURG, Md., Jan. 16, 2017 — Using a special circuit to generate microwave photons stripped of intensity fluctuations, physicists at the National Institute of Standards and Technology (NIST) have cooled a mechanical object to a temperature lower than previously thought...
Individual Photons Squeezed by QDs
CAMBRIDGE, England, Aug. 31, 2015 — Quantum dots can provide the control necessary to "squeeze" individual photons — a feat previously considered impossible to observe. Squeezing is quantum phenomenon that produces an extremely low-noise signal potentially useful in technology...
Squeezed Light Transmitted Through Air
ERLANGEN, Germany, Sept. 16, 2014 — German scientists have overcome a theoretical hurdle by transmitting a pulse of squeezed light over a long distance through the air.
On-chip squeezed light could improve sensors
PASADENA, Calif. – A microchip-based way to create squeezed light could assist a range of precision measurements and provide a viable route toward real-world on-chip sensor applications and technology. Monitoring a mechanical object’s motion, even with a touch...

Squeezed light measures moving target
TOKYO – A novel quantum mechanical squeezing technique that precisely tracks the phase of optical waveforms in motion has broken the standard limits for ultraprecise measurement by exploiting quantum lightwaves in a different way. In optical communications,...
Moving Target Measured with Squeezed Light
TOKYO, Sept. 24, 2012 — A novel quantum mechanical squeezing technique that precisely tracks the phase of optical waveforms in motion has broken the standard limits for ultraprecise measurement by exploiting quantum lightwaves in a different way.
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.
Squeezed light helps measure gravitational waves
HANNOVER, Germany – A new “squeezed light” method improves the sensitivity and accuracy of the interferometers used to measure gravitational waves. Observing the gravitational waves that result from supernova explosions and other cosmic events requires...
“Optics table on a chip” superpositions photons
GAITHERSBURG, Md. – A tiny, tunable superconducting circuit can place a single microwave photon in two frequencies simultaneously, potentially leading to the long-sought “optics table on a chip.” Researchers at the National Institute of Standards and...
Squeezed Light From Single Atoms
GARCHING, Germany, July 11, 2011 — Researchers have shown that an atom interacting with light inside a cavity can alter the wavelike properties of the light, reducing its amplitude or phase fluctuations below the level allowed for classical electromagnetic radiation. The team,...
'Squeezed Light' Record Set
HANOVER, Germany, Jan. 29, 2008 -- An extremely high-quality green laser beam has allowed a record number of photons to be placed in a specific order for use in gravitational wave detectors. Ordering the photons reduced fluctuations in the intensity of the light by 90 percent. This...
