Quantum algorithms company Phasecraft has announced a groundbreaking partnership with Quantinuum. The collaboration aims to combine Phasecraft’s cutting-edge quantum algorithms with Quantinuum’s state-of-the-art hardware to accelerate the path to quantum advantage. As part of the partnership, Phasecraft will gain access to Quantinuum’s System Model H2, a quantum computer with industry-leading 2-qubit gate fidelities of 99.9%. This will enable Phasecraft to run advanced algorithms and tackle ambitious applications in materials science and beyond. In return, Quantinuum will license Phasecraft’s patented compact encoding technology, a highly efficient method for encoding solid-state systems on quantum computers, for non-commercial research. “This collaboration is a major milestone in our mission [...]

CEA-Leti, in collaboration with Quobly, CEA-List, and CEA-Irig, has unveiled a cryo-CMOS charge-readout IC capable of simultaneous microsecond readouts for multiple qubits, achieving a record-low power consumption of 18.5μW per qubit. Presented at ISSCC 2025, the solution leverages FD-SOI CMOS technology and a capacitive-feedback transimpedance amplifier (CTIA) to enable 4- and 16-point quadrature-amplitude modulation (QAM), significantly reducing power use by 10x and footprint by 2x compared to existing methods. The innovation addresses key scalability challenges in quantum computing, such as wiring bottlenecks and cryogenic power constraints. Quentin Schmidt, lead author of the paper, noted, “This approach allows for efficient multiplexing of qubits, paving the way for scalable [...]

A team at QuTech, a collaboration between TU Delft and TNO, has demonstrated the initialization, readout, and universal control of four qubits encoded in eight germanium quantum dots. Published in Nature Nanotechnology and featured on its February issue cover, this work marks a significant step toward scalable quantum computing using semiconductor qubits. The researchers created a 4×2 array of quantum dots, enabling precise control and coupling of four qubits, a critical requirement for large-scale quantum systems. The team achieved high-fidelity quantum information transfer and entanglement swapping across qubits, with a 75% Bell state fidelity between the first and fourth qubits. This demonstrates the system’s capability to perform [...]

American Binary has introduced Ambit Client, the first enterprise VPN solution fully compliant with the NSA’s CNSA 2.0 standard for quantum resistance. Designed to counter "Harvest Now, Decrypt Later" (HNDL) attacks, Ambit Client ensures complete protection across all four cryptographic components required by CNSA 2.0: digital signatures, key exchange, bulk encryption (AEAD), and hashing. This includes the implementation of ML-KEM 1024 cryptography, which is mathematically proven to resist both classical and quantum attacks. Unlike traditional VPNs that rely on vulnerable methods like Diffie-Hellman key exchange or elliptic-curve cryptography, Ambit Client addresses the quantum security gap by providing end-to-end quantum resistance. Kevin Kane, CEO of American Binary, emphasized, “The quantum threat is not a future [...]

The Quantum Economic Development Consortium (QED-C) has announced significant progress in cryogenic technologies, supported by a NIST-funded R&D program. Four QED-C members—FormFactor, Northrop Grumman, Quantum Opus, and Triton Systems—have achieved advancements in cryogenics, a critical enabler for quantum computing, sensing, and communication systems. The $877,000 program, co-funded by NIST and the participating companies, has driven innovations in energy-efficient, compact, and cost-effective cryogenic solutions. FormFactor developed a high-speed cryogenic testing system for quantum chips, capable of testing complex dies with hundreds of connections at temperatures as low as 2 Kelvin (-271 °C) in just two hours. This research led to the commercialization of the HPD IQ2000 chip scale prober, which [...]

The Materiel and IT Command (COMMIT) of the Dutch Ministry of Defence has officially launched the Quantum Challenges, an initiative aimed at addressing technical and operational quantum challenges through innovative solutions. Six participants, including start-ups, knowledge institutes, and universities such as QuiX Quantum, TNO, and Eindhoven University of Technology, were selected to collaborate on this eight-month project. The initiative focuses on fostering collaboration between the Ministry of Defence and the quantum ecosystem, with participants developing solutions for specific defence-related use cases. The results will be showcased at Purple NECtar/Innovation in Defence in November 2025, where the best solutions will receive follow-up assignments. COMMIT aims to not only solve its own challenges [...]

Kipu Quantum has partnered with IBM Quantum to launch a new optimization function in the Qiskit Functions Catalog, a platform designed to simplify quantum application workflows. The new function, “Iskay Quantum Optimizer,” leverages Kipu Quantum’s Bias-Field Digitized Counterdiabatic Quantum Optimization BF-DCQO algorithm algorithm, offering a powerful tool for solving complex optimization problems on IBM’s quantum hardware.The BF-DCQO algorithm, developed by Kipu Quantum, has demonstrated superior performance in solving higher-order unconstrained binary optimization (HUBO) problems, outperforming classical methods and existing quantum algorithms like the Quantum Approximate Optimization Algorithm (QAOA) and quantum annealing. The algorithm’s ability to handle large-scale optimization tasks efficiently makes [...]

Highlighting projects such as “Curiosity” and the Quantum Casino, [...]

Figure 1 - Microsoft's Eight Qubit Majorana 1 Device. Credit: Microsoft Introduction After almost 20 years of development, Microsoft has developed a controllable topological qubit module design that they intend on scaling up very quickly to produce a 1 million qubit error corrected quantum computer within a few years. In theory, a topological qubit could provide the optimal type of qubit because it combines three desirable properties together without requiring tradeoffs: Reliability, Speed, and Size. In practice, the topological qubit has been very difficult to build because it depends on leveraging Majorana zero modes (MZMs) which hitherto was only a theoretical [...]
