Astronomers Identify Best Type Ia Supernovae for Measuring Cosmic Distances

The brilliant explosions of dead stars have been used for years to illuminate the far-flung reaches of our cosmos. The explosions, called Type Ia supernovae, allow astronomers to measure the distances to galaxies and measure the ever-increasing rate at which our universe is stretching apart. [More]
Single Photon Successfully Entangles 3,000 Atoms

Single Photon Successfully Entangles 3,000 Atoms

Physicists from MIT and the University of Belgrade have developed a new technique that can successfully entangle 3,000 atoms using only a single photon. The results, published today in the journal Nature, represent the largest number of particles that have ever been mutually entangled experimentally. [More]

Scientists Observe Converging Point of Classical and Quantum Behavior

If we are ever to fully harness the power of light for use in optical devices, it is necessary to understand photons - the fundamental unit of light. Achieving such understanding, however, is easier said than done. That's because the physical behavior of photons - similar to electrons and other sub-atomic particles - is characterized not by classical physics, but by quantum mechanics. [More]

Orbital Angular Momentum for Encoding Information Increases Possibility of High-Dimensional Quantum Key Distribution

Orbital Angular Momentum for Encoding Information Increases Possibility of High-Dimensional Quantum Key Distribution

Researchers at the University of Rochester and their collaborators have developed a way to transfer 2.05 bits per photon by using "twisted light." This remarkable achievement is possible because the researchers used the orbital angular momentum of the photons to encode information, rather than the more commonly used polarization of light.

CQP Researchers Publish Paper on Active Temporal Multiplexing of Photons in arXiv

A paper co-authored by researchers including Gabriel Mendoza, Raffaele Santagati, Jack Munns, Lizzy Hemsley, Mateusz Piekarek, Enrique Martin-Lopez, Graham Marshall, Damien Bonneau, Mark Thompson and Jeremy O'Brien from the Centre for Quantum Photonics has been published in arXiv this month. [More]
Quantum Dots Help Sharpen Nanoscale Microscopy

Quantum Dots Help Sharpen Nanoscale Microscopy

The 2014 chemistry Nobel Prize recognized important microscopy research that enabled greatly improved spatial resolution. This innovation, resulting in nanometer resolution, was made possible by making the source (the emitter) of the illumination quite small and by moving it quite close to the object being imaged.

Novel Technique Creates Ultra-Precise Laser Beam Using a Quantum Frequency Filter

Novel Technique Creates Ultra-Precise Laser Beam Using a Quantum Frequency Filter

Atomic clocks are the most accurate clocks in the world. In an atomic clock, electrons jumping from one orbit to another decides the clock's frequency. To get the electrons to jump, researchers shine light on the atoms using stabilised laser light. However, the laser light has to have a very precise frequency to trigger very precise electron jumps. It is however challenging to get the laser light frequency ultra precise - there will always be a little 'noise'. [More]
Entanglement Can Improve Performance of Optical Sensors

Entanglement Can Improve Performance of Optical Sensors

The extraordinary promise of quantum information processing — solving problems that classical computers can’t, perfectly secure communication — depends on a phenomenon called “entanglement,” in which the physical states of different quantum particles become interrelated. But entanglement is very fragile, and the difficulty of preserving it is a major obstacle to developing practical quantum information systems. [More]
Quantum Imaging Centre Opens at the Glasgow Science Centre

Quantum Imaging Centre Opens at the Glasgow Science Centre

Based in Glasgow, QuantIC, the Quantum Imaging Centre, will commercialise cameras built with newly-developed quantum technology, with the potential to create affordable handheld video cameras capable of seeing areas of the spectrum only previously visible with large and expensive devices. More than 30 industry partners will help QuantIC’s imaging systems bring new benefits to the UK economy. [More]
