The Quantum Principle of Relativity
According to theorists from universities in Warsaw and Oxford, the most important features of the quantum world may result from the special theory of relativity, which until now seemed to have little to do with
Entangled photons for imaging and measurement techniques
A team of researchers from the Fraunhofer Institute for Applied Optics and Precision Engineering IOF in Jena has developed a quantum imaging solution that can facilitate highly detailed insights into tissue samples using extreme spectral
High-quality photon entanglement out of a stand-alone silicon chip
The fruitful association of quantum and integrated photonics holds the promise to produce, manipulate, and detect quantum states of light using compact and scalable systems. Integrating all the building blocks necessary to produce high-quality photonic
Tools for the performance optimization of single-photon QKD
Quantum light sources emitting triggered single photons or entangled photon pairs have the potential to boost the performance of quantum key distribution (QKD) systems. Proof-of-principle experiments affirmed these prospects, but further efforts are necessary to
Quantum-entangled light from a vibrating membrane
Researchers from the Quantum Optomechanics group at the Niels Bohr Institute, University of Copenhagen, recently entangled two laser beams through bouncing them off the same mechanical resonator, a tensioned membrane. This provides a novel way
New quantum technology could diagnose and treat heart condition
Atrial fibrillation (AF) is a heart condition that causes an irregular and abnormally fast heart rate, potentially leading to blood clots, stroke, heart failure and other heart-related complications. AF is commonly diagnosed using an electrocardiogram
Auto-tuning qubits using AI
Scientists at the National Institute of Standards and Technology (NIST) has proposed that the best way to tune qubits is using an AI. The team outlines a way to teach an AI to make an
Broken time-reversal symmetry in superconducting UPt3
Researchers at the University of Notre Dame, in partnership with those at Northwestern University, are a step closer to understanding how superconductors can be improved for reliability in future quantum computers. The team, led by
Tiny optical cavity could make Quantum Internet possible
Engineers at Caltech have shown that atoms in optical cavity could be foundational to the creation of a Quantum Internet. The researchers constructed a nanophotonic cavity, a beam that is about 10 microns in length
New entangled photon source for more secure QKD
An international team has developed a new method for generating quantum-entangled photons in a spectral range of light that was previously inaccessible. The team has developed a new method for generating and detecting quantum-entangled photons
