QphoX B.V., a Dutch quantum technology startup that is developing leading frequency conversion systems for quantum applications, Rigetti Computing, Inc., a pioneer in full-stack quantum-classical computing, and Qblox, a leading innovator in quantum control stack development, today announced that their joint research demonstrating the ability to readout superconducting qubits with an optical transducer was published in Nature Physics.

Quandela, the European leader in photonic quantum computing, announces a major breakthrough for the sector in a scientific paper describing a reduction by a factor of 100,000 in the number of components required for fault-tolerant calculations. Quandela’s hybrid approach, based on a technology that generates photonic qubits with unprecedented efficiency from artificial atoms (semiconductor quantum emitters), should enable the company to accelerate the scaling-up of its quantum computers.

PsiQuantum has successfully completed the research & development viability phase of the Defense Advanced Research Projects Agency's (DARPA) Utility-Scale Quantum Computing program and is now entering the validation phase of the program. In this final phase, DARPA will evaluate PsiQuantum’s utility scale system design, component and system performance to specification, and application use cases and economic utility. This next and final phase of work marks another significant milestone in PsiQuantum's roadmap to develop the world’s first utility-scale, fault-tolerant quantum computers on the fastest timeline possible.

IQMQuantum Computers, Riverlane, and Zurich Instruments have announced the launchof the SurgeonQ project, a strategic collaboration to create the first quantumcomputing platform capable of running multiple real-time quantum errorcorrection operations. The project represents progress towards commerciallyviable quantum computing systems.

SEALSQ Corp ("SEALSQ" or "Company"), a company that focuses on developing and selling Semiconductors, PKI, and Post-Quantum technology hardware and software products, today announced that it will host SEALSQ Quantum Day at NASDAQ on February 11, 2025, featuring a high-profile Roundtable Discussion following the NASDAQ Closing Bell Ceremony. The event will focus on the United States' strategic need for technological independence in semiconductors, post-quantum artificial intelligence (AI), and cybersecurity, which are critical for national security, economic growth, and technological leadership.

Scientists at the National Institute of Standards and Technology (NIST) have created a new thermometer using atoms boosted to such high energy levels that they are a thousand times larger than normal. By monitoring how these giant “Rydberg” atoms interact with heat in their environment, researchers can measure temperature with remarkable accuracy. The thermometer’s sensitivity could improve temperature measurements in fields ranging from quantum research to industrial manufacturing.

Quantum Computing Inc. (“QCi” or the “Company”), an innovative, integrated photonics and quantum optics technology company, today announced it has received a fifth purchase order for its thin film lithium niobate (TFLN) photonic chip foundry. The latest order comes from a research group based in Canada to support its research efforts on quantum photonics.

SandboxAQ announced today it has signed an agreement with Aramco, one of the world’s leading integrated energy and chemicals companies, to collaborate on developing a multi-GPU enabled differentiable computational fluid dynamics solver for application in oil and gas processing facilities.

The University of Strathclyde has partnered with the National Physical Laboratory (NPL) and Quantum Motion to develop new ways to overcome the challenges of running quantum control electronics in extremely cold conditions.

Quintessent Inc., a pioneer in quantum dot laser technology and heterogeneous silicon photonics, and IQE plc, the leading global supplier of advanced epitaxial wafer products and services, have partnered together to establish the world’s first large-scale quantum dot laser and semiconductor optical amplifier (SOA) epitaxial wafer supply chain. This collaboration, supported by purchase order commitments from Quintessent, will see IQE deliver production quantities of epitaxial wafers to Quintessent throughout 2025.
