High coherence and low cross-talk in a superconducting qubit architecture

 Quantum Physics News
 29 April 2022
In a new report now published in Science Advances, Peter A. Spring and a team of scientists in physics at the Oxford University described qubit coherence and low cross-talk and single-qubit gate errors in superconducting qubit architecture, suited for two-dimensional (2D) lattices of qubits. The...

Physicists are re-examining the foundations of quantum physics from the perspective of momentum and exploring what happens when the momentum of light is reduced to zero. ...

Study points to physical principles that underlie quantum Darwinism

 Quantum Physics News
 27 April 2022
At the atomic and subatomic scales, objects behave in ways that challenge the classical worldview based on day-to-day interactions with macroscopic reality. A familiar example is the discovery that electrons can behave as both particles and waves, depending on the experimental context in which they...

Research has found a new way to create nano-sized magnetic particles using ultrafast laser light pulses. The discovery could pave the way for new and more energy-efficient technical components and become useful in the quantum computers of the future. ...

New and surprising duality found in theoretical particle physics

 Quantum Physics News
 25 April 2022
A new and surprising duality has been discovered in theoretical particle physics. The duality exists between two types of scattering processes that can occur in the proton collisions made in the Large Hadron Collider at CERN in Switzerland and France. The fact that this connection can, surprisingly,...
