Scientists have demonstrated that wires more than 100 times thinner than a human hair can act like a quantum one-way street for electrons when made of a peculiar material known as a topological insulator. The […]
Boson Sampling is a computational paradigm representing one of the most viable and pursued approaches to demonstrate the regime of quantum advantage. Recent results have shown significant technological leaps in single-photon generation and detection, leading […]
Researchers at the Max Planck Institute of Quantum Optics succeeded in massively improving the performance of a component that is crucial to optical quantum systems. Future quantum computers are expected not only to solve particularly […]
A new two-path-interference experiment has been designed at TU Wien that only has to measure one specific particle to prove quantum superposition. A single neutron is measured at a specific position — and due to […]
A team of researchers from Université Paris-Saclay, the University of Ulm and the Institute of Quantum Technologies has developed an on-chip circuit that produces up to six microwave photons at the same time. The circuit […]
The mixing of conduction band valleys plays a critical role in determining electronic spectrum and dynamics in a silicon nanostructure. Researchers have investigated theoretically how valley–orbit coupling affects the exchange interaction in a silicon double […]
Computational detective work by physicists has confirmed cerium zirconium pyrochlore is a 3D quantum spin liquid, a solid material in which quantum entanglement and the geometric arrangement of atoms cause electrons to fluctuate between quantum […]
Quantum entanglement is a key resource in quantum technology, and its quantification is a vital task in the current noisy intermediate-scale quantum (NISQ) era. Researchers have combined hybrid quantum-classical computation and quasi-probability decomposition to propose […]
In quantum mechanics, the act of measurement produces unavoidable perturbation (also called “back-action”) on the state of the measured system. This effect is, in many cases, not desirable, as back-action often limits the precision of […]
A collaboration between Harvard University with scientists at QuEra Computing, MIT, University of Innsbruck and other institutions has demonstrated a breakthrough application of neutral-atom quantum processors to solve problems of practical use. Previously, neutral-atom quantum […]
