Quantinuum extends its significant lead in quantum computing, achieving historic milestones for hardware fidelity and Quantum Volume
Posted by Cecile G. Tamura in categories: computing, quantum physics
‘Three Nines’ Surpassed: Quantinuum Notches Milestones For Hardware Fidelity And Quantum Volume Formed in 2021, Quantinuum is the combination of the quantum hardware team from Honeywell Quantum Solutions (HQS) and the quantum software team at Cambridge Quantum Computing, HQS was founded in 2014.
Quantinuum has raised the bar for the global ecosystem by achieving the historic and much-vaunted “three 9’s” 2-qubit gate fidelity in its commercial quantum computer and announcing that its Quantum Volume has surpassed one million – exponentially higher than its nearest competitors.

Quantum Systems: Potential Improvements and Future Developments
Posted by Laurence Tognetti, Labroots Inc. in categories: computing, particle physics, quantum physics
“Interfacing two key devices together is a crucial step forward in allowing quantum networking, and we are really excited to be the first team to have been able to demonstrate this,” said Dr. Sarah Thomas.
How close are we to making quantum computing a reality? This is what a recent study published in Science Advances hopes to address as an international team of researchers discuss recent progress in how quantum information is both stored and then transmitted over long distances using a quantum memory device, which scientists have attempted to develop for some time. This study holds the potential to help scientists better understand the processes responsible for not only making quantum computing a reality, but also enabling it to work as seamlessly as possible.
While traditional telecommunications technology uses “repeaters” to prevent the loss of information over long distances, quantum computing cannot use such technology since it will destroy quantum information along the way. While quantum computing uses photons (particles of light) to send information, storing the information using a quantum memory device for further dissemination has eluded researchers for some time. Therefore, to combat the problem of sending quantum information over long distances, two devices are required: the first will send the quantum information while the second will store them for later dissemination.

Internet can achieve quantum speed with light saved as sound
Posted by Saúl Morales Rodriguéz in categories: internet, quantum physics
Researchers at the University of Copenhagen’s Niels Bohr Institute have developed a new way to create quantum memory: A small drum can store data sent with light in its sonic vibrations, and then forward the data with new light sources when needed again. The results demonstrate that mechanical memory for quantum data could be the strategy that paves the way for an ultra-secure internet with incredible speeds.
