Credit: Horizon Quantum Computing It's no secret that the best way to achieve maximum performance from a quantum system is to establish a very tight integration between the hardware and software stacks. This allows the software to take advantage of all the idiosyncrasies in the hardware to obtain every ounce of performance that it can. And achieving this maximum performance is surely needed as the industry races to achieve systems that can provide [...]

SemiQon has completed its quantum processor testing and measurement facilities at the premises of the Finnish National Metrology Institute VTT MIKES. The company is the first to operate in this environment, leveraging world-class infrastructure for low-noise, high-precision measurement necessary for advancing scalable quantum hardware. This setup includes a cryogenic measurement system with a 5 Tesla magnetic field and operates at 400 millikelvin to 1 kelvin, higher temperatures than typical superconducting chips which reduces cryogenic requirements. Additionally, the facilities house a probe-station for full-scale wafer probing and various state-of-the-art qubit measurement equipment. The partnership with VTT MIKES boosts the interest in and [...]

QuEra Computing has announced the addition of local qubit control, also known as local detuning, to its 256-qubit quantum computer, Aquila. This new capability enhances the flexibility and programmability of Aquila, allowing users to independently control and manipulate qubits. Aquila's users now have more versatility when addressing problems in areas such as machine learning, optimization, and simulation. The local detuning feature opens up the potential for a broader range of input data and problem types by enabling the individual preparation of qubit states. Two other new capabilities that are also now available include taller geometries with increased lattice height, and tighter [...]

Xanadu, a leader in photonic quantum computing, and South Carolina Quantum (SC Quantum), a non-profit organization focused on creating a sustainable quantum ecosystem, have entered into a partnership to enhance quantum education and research across South Carolina and the Southeast United States. This collaboration aims to create practical educational materials and grow a skilled quantum workforce in the region. Xanadu's expansion in the United States and support for quantum education align with SC Quantum's mission to develop quantum talent and technology. The partnership will leverage Xanadu's open-source software framework, PennyLane, enabling SC Quantum's network to design and test next-generation quantum algorithms [...]

Riverlane has been selected for Phase 2 of DARPA's Quantum Benchmarking program, which aims to design quantum computing metrics for practical problems and estimate quantum and classical resources needed for critical performance thresholds. Riverlane's mission aligns with the program's goals, focusing on error correction and fault tolerance to achieve a useful quantum advantage in various fields. The project involves collaboration with top universities and national labs including the University of Southern California, the University of Sydney and the Los Alamos National Laboratory (LANL) to identify benchmarks for practical issues in plasma physics, fluid dynamics, condensed matter, and high-energy physics. The team [...]

Credit: Qunnect Qunnect, a leader in quantum networking technology, announced record-breaking performance in distributing polarization qubits on the GothamQ Network in New York City. Utilizing existing commercial fiber optic cable, Qunnect achieved transmission rates of 500,000 pairs of high-fidelity entangled photons per second with network uptime above 99%. This advancement demonstrates the viability of Qunnect's quantum networking components for prolonged, real-world deployment. Qunnect's innovative approach uses room-temperature atoms to generate polarization entangled photons, enabling compatibility with other quantum devices such as sensors and computers. The QU-SRC entangled photon source [...]

Progression of Quantuum's Improvements in Quantum Volume Performance. Credit: Quantinuum Quantinuum has always had a strategy of providing users with qubits that demonstrated the highest possible measure of qubit quality, as measured by both gate fidelity metrics as well as the Quantum Volume measure originally proposed by IBM. In fact, in 2020, they declared a goal of continuing to improve the Quantum Volume measure of their machines by a factor of 10X each year. And to their credit, they have continued to meet or beat this goal every year. Now, they have reached a new level of qubit quality performance on [...]

How to Celebrate a Hundred Years of Quantum Mechanics Bard Professor Paul Cadden-Zimansky wants everyone from kindergarteners to CEOs to celebrate the International Year of Quantum Science and Technology in 2025. One of his goals for the initiative is to illustrate the many pathways to jobs in science and technology. He shares his own story that includes both a C in high school physics and a successful career as a professor and superconductivity researcher. Paul Cadden-Zimansky is an associate professor of physics and director of the Physics Program at Bard College. A condensed matter physicist, Paul earned his Ph.D. from Northwestern [...]
