The result highlights a fundamental tension: Either the rules of quantum mechanics don’t always apply, or at least one basic assumption about reality must be wrong. Some excerpts of this very amazing article in QuantaMagazine,
Researchers from the Centre of Excellence for Quantum Computation and Communication Technology (CQC2T) working with Silicon Quantum Computing (SQC) have located the ‘sweet spot‘ for positioning qubits in silicon to scale up atom-based quantum processors.
Researchers at Sandia National Laboratories propose a very large family of benchmarks for probing the performance of quantum computers. They call them Volumetric Benchmarks (VBs) because they generalize IBM’s benchmark for measuring Quantum Volume. The Quantum Volume
Parametrized quantum optical circuits are a class of quantum circuits in which the carriers of quantum information are photons and the gates are optical transformations. Classically optimizing these circuits is challenging due to the infinite
Creating perfect entanglement requires full control over all qubit-qubit interactions. Until now, this goal has been hindered by the presence of an always-on and fundamental parasitic interaction that disturbs entanglement. Now, researchers at Forschungszentrum Jülich
Moscow State University in Russia is developing a quantum computer on an optical chip and aims to achieve 50 qubits using French startup Quandela’s technology. The highly efficient photonic quantum bit sources support Russian quantum
Trapping and controlling electrons in bilayer graphene quantum dots yields a promising platform for quantum information technologies. Researchers at UC Santa Cruz have now achieved the first direct visualization of quantum dots in bilayer graphene,
Platforms of Rydberg atoms have been proposed as promising candidates to solve some combinatorial NP-hard optimization problems. A team of scientists at Atos Quantum Lab has computed quantitative requirements on the system sizes and noise
Researchers at the National Institute of Standards and Technology (NIST) have invented a miniature thermometer with big potential applications such as monitoring the temperature of processor chips in superconductor-based quantum computers, which must stay cold
A team led by University of New South Wales (UNSW) has found that removing random doping in quantum electronic devices dramatically improves their reproducibility. That is a key requirement for future applications such as quantum-information
