A 2D device for quantum cooling
To perform quantum computations, quantum bits (qubits) must be cooled down to temperatures in the millikelvin range (close to -273 Celsius), to slow down atomic motion and minimize noise. However,…
Scientists at uOttawa develop innovative method to validate quantum photonics circuits performance
A team of researchers from the University of Ottawa’s Nexus for Quantum Technologies Institute (NexQT), led by Dr. Francesco Di Colandrea under the supervision of Professor Ebrahim Karimi, associate professor…
Quantum entanglement measures Earth rotation
A team of researchers led by Philip Walther at the University of Vienna carried out a pioneering experiment where they measured the effect of the rotation of Earth on quantum…
Magnetic avalanche triggered by quantum effects
Iron screws and other so-called ferromagnetic materials are made up of atoms with electrons that act like little magnets. Normally, the orientations of the magnets are aligned within one region…
The world is one step closer to secure quantum communication on a global scale
Researchers at the University of Waterloo’s Institute for Quantum Computing (IQC) have brought together two Nobel prize-winning research concepts to advance the field of quantum communication. Scientists can now efficiently…
Physicists discover a quantum state with a new type of emergent particles: Six-flux composite fermions
If the fractional quantum Hall regime were a series of highways, these highways would have either two or four lanes. The flow of the two-flux or four-flux composite fermions, like…
A new design for quantum computers
Creating a quantum computer powerful enough to tackle problems we cannot solve with current computers remains a big challenge for quantum physicists. A well-functioning quantum simulator — a specific type…
Technique could improve the sensitivity of quantum sensing devices
In quantum sensing, atomic-scale quantum systems are used to measure electromagnetic fields, as well as properties like rotation, acceleration, and distance, far more precisely than classical sensors can. The technology…
Shining a light on the hidden properties of quantum materials
Certain materials have desirable properties that are hidden, and just as you would use a flashlight to see in the dark, scientists can use light to uncover these properties. Researchers…
Towards the quantum of sound
The quantum ground state of an acoustic wave of a certain frequency can be reached by completely cooling the system. In this way, the number of quantum particles, the so-called…
