KDDI Research, Inc. (“KDDI Research”), and Toshiba Digital Solutions Corporation (“Toshiba Digital Solutions”) have developed a multiplexing technology for quantum key distribution (QKD) that is theoretically impossible to eavesdrop. This technology assigns secret keys to the C-band and high-volume data signals to the O-band, enabling multiplexed transmission over a single optical fiber. Furthermore, utilizing this technology, we have successfully transmitted secret keys and high-capacity data signals at 33.4 Tbps over 80 km for the first time.

Today, Amazon Web Services (AWS) announced Ocelot, a new quantum computing chip that can reduce the costs of implementing quantum error correction by up to 90%, compared to current approaches. Developed by the team at the AWS Center for Quantum Computing at the California Institute of Technology, Ocelot represents a breakthrough in the pursuit to build fault-tolerant quantum computers capable of solving problems of commercial and scientific importance that are beyond the reach of today’s conventional computers.

In a milestone that brings quantum computing tangibly closer to large-scale practical use, scientists at Oxford University Physics have demonstrated the first instance of distributed quantum computing. Using a photonic network interface, they successfully linked two separate quantum processors to form a single, fully connected quantum computer, paving the way to tackling computational challenges previously out of reach. The results have been published today in Nature.

The procurement contract for MareNostrum-Ona, the EuroHPC quantum computer to be located in Spain, has been signed by the European High Performance Computing Joint Undertaking (EuroHPC JU) and Qilimanjaro Quantum Tech, the selected vendor.

a team of Harvard scientists has succeeded for the first time in trapping molecules to perform quantum operations. This feat was accomplished by using ultra-cold polar molecules as qubits, or the fundamental units of information that power the technology. The findings, recently published in the journal Nature, open new realms of possibility for harnessing the complexity of molecular structures for future applications.

the U.S. Department of Energy (DOE) announced $71 million in funding for 25 projects in high energy physics that will use the emerging technologies of quantum information science to answer fundamental questions about the universe.

Infleqtion, the world’s leading quantum information company, today announced its receipt of $11 million in funding from the U.S. Department of Defense (DoD) as part of the latest tranche of awards under the Accelerate the Procurement and Fielding of Innovative Technologies (APFIT) program. This funding supports Infleqtion’s work on the Rack Mounted Optical Clocks project, with Tiqker at the forefront, driving advancements in precision timing solutions—critical for enhancing military operational readiness, secure communications, and mission success in contested environments.

Quantum sensors pave the way for innovation in sensing technology. They are set to revolutionise a variety of sectors, spanning from health care to space and defence. VTT Technical Research Centre of Finland is at the forefront of quantum sensor development, aiming to commercialise the technology for the benefit of many. The research institute strongly believes that broader adoption of quantum technologies has a strong and positive societal and environmental impact.

In an article published September 23, 2024 in the journal Physical Review A, JQI researchers proposed a way to use the physics of superconducting junctions to let each function as more than one qubit. They also outlined a method to use the new qubit design in quantum simulations. While these proposed qubits might not immediately replace their more established peers, they illustrate the rich variety of quantum physics that remains to be explored and harnessed in the field.

Oxford Ionics, a world leader in trapped-ion quantum computing, today announced that it has won a contract, alongside Infineon Technologies AG, to build a state-of-the-art portable quantum computer for Agentur für Innovation in der Cybersicherheit GmbH, or 'Cyberagentur'. Oxford Ionics and Infineon are one of three independent contractors selected by Cyberagentur, who is investing a total of €35M into the project.
