Over 1,000 Controllable Atomic Qubits Achieved

In a research article just published on the arXiv preprint server the research team from TU Darmstadt in Germany reports on the world’s first successful experiment to realise a quantum-processing architecture that contains more than 1,000 atomic qubits in one single plane.

The researchers used a novel method of “quantum bit supercharging” that enabled researchers to overcome the limitations imposed by the performance of lasers on the number of usable qubits. By implementing this method, 1305 single-atom qubits were successfully loaded into a quantum array with 3,000 trap sites and reassembled into defect-free target structures containing up to 441 qubits. Utilizing several laser sources in parallel, this approach addressed what was previously considered to be an insurmountable technological barriers.

The paper further outlines how increasing the number of laser sources could enable the use of 10,000 qubits and beyond in the coming years.

For many applications, 1,000 qubits is regarded as the threshold value at which the efficiency boost promised by quantum computers can be demonstrated, i.e. the threshold to achieving quantum supremacy.

I am the Founder of Applied Quantum (AppliedQuantum.com), a research-driven professional services firm dedicated to helping organizations unlock the transformative power of quantum technologies. Alongside leading its specialized service, Secure Quantum (SecureQuantum.com)—focused on quantum resilience and post-quantum cryptography—I also invest in cutting-edge quantum ventures through Quantum.Partners. Currently, I’m completing a PhD in Quantum Computing and authoring an upcoming book “Practical Quantum Resistance” (QuantumResistance.com) while regularly sharing news and insights on quantum computing and quantum security at PostQuantum.com. I’m primarily a cybersecurity and tech risk expert with more than three decades of experience, particularly in critical infrastructure cyber protection. That focus drew me into quantum computing in the early 2000s, and I’ve been captivated by its opportunities and risks ever since. So my experience in quantum tech stretches back decades, having previously founded Boston Photonics and PQ Defense where I engaged in quantum-related R&D well before the field’s mainstream emergence. Today, with quantum computing finally on the horizon, I’ve returned to a 100% focus on quantum technology and its associated risks—drawing on my quantum and AI background, decades of cybersecurity expertise, and experience overseeing major technology transformations—all to help organizations and nations safeguard themselves against quantum threats and capitalize on quantum-driven opportunities.
