Naturally Occurring Vibrations in Artificial Atoms Could Be Used to Build Quantum Sensors
BRISTOL, England, Aug. 19, 2019 — The discrete nature of photons that are emitted from individual atoms ensures low fluctuations in brightness, as only one photon is emitted at a time. Scientists believe this property could be useful in developing future quantum technologies where...
Coral Health Monitored with Robots, Hyperspectral Imaging
BRISTOL, England, March 12, 2019 — A fluorescence hyperspectral camera mounted on an underwater remotely operated vehicle (ROV) is being developed by scientists at the University of Bristol and Sealife London Aquarium to cost-effectively monitor coral health. Corals and the...
UCL, Google Begin Quantum Computing Partnership
LONDON, Nov. 9, 2018 — University College London (UCL) is joining forces with Google to launch a £5.5 million ($7.2 million) Prosperity Partnership, which aims to harness the revolutionary power of quantum computers for applications in modeling and simulation. The...
International Team Engineers Silicon Chip for Quantum Information Processing
BRISTOL, England, Aug. 24, 2018 — An international team led by the University of Bristol has demonstrated the ability to control two qubits of information within a single silicon chip. This programmable two-qubit quantum processor could be used as a tool to perform quantum...
Researchers Use Silicon Photonics to Create Quantum Random Number Generator
BRISTOL, England, July 30, 2018 — A chip-based device measuring just 1 sq mm has demonstrated the potential to generate quantum-based random numbers at gigabit (Gb)-per-second speeds, using minimal power. The tiny device, which is enabled by silicon photonics, could be used as a...

Quantum mystery of light revealed
BRISTOL, UK, and NICE, France – A unique setup involving an integrated photonic quantum chip in a quantum beamsplitter is helping to answer one of the most fundamental questions in physics: Is light made of waves or particles? Debates on the particle-wave theories of light have...
Photons Observed as Particles, Waves Simultaneously
BRISTOL, England, and NICE, France, Nov. 5, 2012 — It is well-known that photons can act like waves or particles, depending on how they are measured experimentally. But they have never been seen exhibiting both behaviors at the same time — until now. The particle-wave theories of light were...
Silicon could enable mass production of quantum computing
BRISTOL, UK – A new silicon-based approach to quantum computing could make the technology easier to mass-produce. Scientists at the University of Bristol’s Centre for Quantum Photonics, leading an international collaboration, made the leap from glass-based...
Quantum Computer Recycles Photons
BRISTOL, England, Oct. 25, 2012 — New demonstrations show it is possible to recycle the photons inside a quantum computer so that quantum factoring can be achieved using only one-third of the particles originally required.
