Researchers create new state of light
University of Dayton researchers became the first to create a new “state of light” and showed it also can rotate around a transverse axis perpendicular to the direction light travels, like a cyclone. This new
Quantum computing with exciton-polariton condensates
Researchers at Nanyang Technological University, Singapore, have presented a complete theoretical scheme of quantum computing with exciton-polariton condensates formed in semiconductor micropillars. Exciton-polariton condensates have attractive features for quantum computation, e.g., room temperature operation, high
Defects may be responsible for messy behavior in quantum materials
Researchers are investigating light-emitting defects in materials that may someday form the basis of quantum-based technologies, such as quantum computers, quantum networks or engines that run on light. Once understood, these defects can become controllable
Berkeley Lab to tackle particle physics with Quantum Computing
Massive-scale particle physics produces correspondingly large amounts of data and this is particularly true of the Large Hadron Collider (LHC), the world’s largest particle accelerator, which is housed at the European Organization for Nuclear Research
Quantum teleportation using highly coherent emission from telecom C-band quantum dots
A practical way to link separate nodes in quantum networks is to send photons over the standard telecom fibre network. This requires sub-Poissonian photon sources in the wavelength band around 1550 nm, with photon coherence times
CERN first measurements of certain quantum effects in antimatter
The ALPHA collaboration at CERN has reported the first measurements of certain quantum effects in the energy structure of antihydrogen, the antimatter counterpart of hydrogen. These quantum effects are known to exist in matter, and
Physicists grab individual atoms in groundbreaking experiment
In a first for quantum physics, University of Otago researchers have “held” individual atoms in place and observed previously unseen complex atomic interactions. The team has investigated this quantum process, which until now was only
What if we could teach photons to behave like electrons?
A Stanford-led team has created a pseudo-magnetic force that can precisely control photons. In the short term, this control mechanism could be used to send more internet data through fiber optic cables. In the future, this discovery
A spookily good sensor using quantum entanglement
Scientists from the Research Center for Advanced Science and Technology (RCAST) at The University of Tokyo demonstrated a method for coupling a magnetic sphere with a sensor via the strange power of quantum entanglement. They
MIT proposes more efficient error correction for quantum devices
Researchers at MIT propose a new method which could provide a significant step forward in quantum error correction. It involves fine-tuning the system to address the kinds of noise that are the most likely, rather than casting
