Riken Claims Quantum Breakthrough: Entanglement of Three Spin Qubits

Researchers at Japan’s RIKEN scientific research institute have claimed a breakthrough in quantum computing, increasing the number of silicon-based qubits that can be entangled to three from two, which they say improves the potential of spin qubits for realizing multi-qubit quantum algorithms and effectively addressing quantum error correction. Reporting recently in SciTechDaily, the five researchers […]

Seeqc’s Naples Team Claims 2-Qubit Gate Quantum Milestone

Naples, Italy–April 6, 2021– Digital quantum computing company Seeqc today announced its Naples team, lead by Marco Arzeo, Ph.D., has developed and measured a two-qubit gate. According to the organization, Seeqc’s is the first team in Italy and one of a few international quantum computing firms to achieve this critical engineering milestone. The two-qubit gate […]

New EU Consortium Launches 4-year Quantum Scaling Project

A European consortium has been launched with the goal of scaling silicon quantum technologies. Named QLSI (Quantum Large-Scale Integration with Silicon), it’s a four-year four-year, €15 million ($17.7 million)  EU project coordinated by CEA-Leti, the Grenoble, France-based electronics and IT research institute, and it aims to lay the foundation for industrial-scale semiconductor quantum processors. The […]

Quantum Superiority: How Far Away?

Some technologies, it’s said, are “always 10 years away” – we hear this in reference to autonomous vehicles and quantum computing. Of course, how far away we think they are has a lot to do with how they’re defined. Semi-autonomous cars are here today and becoming smarter with each new model year. As for quantum […]

New Paper: A novel error-correction scheme for quantum computers

By taking advantage of the infinite geometric space of a particular quantum system made up of bosons, the researchers, led by Dr Arne Grimsmo from the University of Sydney, have developed quantum error correction codes that should reduce the number of physical quantum switches, or qubits, required to scale up these machines to a useful size. “The beauty of these codes is they are ‘platform agnostic’ and can be developed to work with a wide range of quantum hardware systems,” Dr Grimsmo said.

Stepping up Qubit research at the DOE

To use quantum computers on a large scale, we need to improve the technology at their heart – qubits. Qubits are the quantum version of conventional computers’ most basic form of information, bits. The DOE’s Office of Science is supporting research into developing the ingredients and recipes to build these challenging qubits.
