So far, superconducting quantum computers have certain constraints on qubit connectivity, such as nearest-neighbor couplings. To overcome this limitation, a team of researchers at RIKEN, Japan, has proposed a scalable architecture to simultaneously connect several
Researchers at Oxford University, in collaboration with DeepMind, University of Basel and Lancaster University, have created a machine learning algorithm that interfaces with a quantum device and ‘tunes’ it faster than human experts, without any
Physicists from Trinity College Dublin have proposed a thermometer based on quantum entanglement that can accurately measure temperatures a billion times colder than those in outer space. These ultra-cold temperatures arise in clouds of atoms,
A research project funded by the U.S. Army has developed a new approach to manufacturing quantum computer chips, representing a significant step forward toward making quantum processors. The research was completed by scientists at the
With the recent technological advancements in quantum computing, scientists face new challenges when it comes to the setup and control of qubit systems. In a webinar (August 20th, 2020 17:00 – 18:00 CEST, 11:00 –
A team of researchers successfully created the first artificial atom using photons as threads to weave electrons together. In contrast to interband excitons in undoped quantum wells, doped quantum wells do not display sharp resonances
MIP* = RE is not a typo. It is a groundbreaking discovery and the catchy title of a recent paper in the field of quantum complexity theory. Complexity theory is a zoo of “complexity classes” of which MIP*and RE are
Amazon announced the general availability of Amazon Braket, a fully managed Amazon Web Services (AWS) product that provides a development environment for exploring and designing novel quantum algorithms. Customers can tap Braket — which launched in preview last
Researchers at IBM T. J. Watson Research Center discovered unexpectedly a new mathematical proof of quantum advantage – the elusive threshold at which quantum computers outperform classical machines in certain use cases. They study shows
Computer scientists at UCLA have shown that existing compilers, which tell quantum computers how to use their circuits to execute quantum programs, inhibit the computers’ ability to achieve optimal performance. Specifically, their research has revealed
