Technology Overview: Principles and Advantages of Cold-Atom Qubits

Cold-atom quantum computing leverages the quantum properties of neutral atoms, typically cooled to microkelvin or nanokelvin temperatures using laser and evaporative cooling techniques. At these ultra-cold temperatures, atoms can be precisely manipulated and trapped in optical lattices or tweezers, forming highly controllable arrays of qubits. The fundamental principle relies on isolating individual atoms—often alkali metals like rubidium or cesium—so their quantum states can be coherently controlled and entangled using laser pulses and magnetic fields.

A key advantage of cold-atom qubits is their exceptional coherence times. Because neutral atoms interact weakly with their environment, they are less susceptible to decoherence compared to solid-state qubits such as superconducting circuits. This property enables longer quantum operations and potentially higher fidelity in quantum gates. Additionally, cold-atom systems are inherently scalable: optical trapping techniques allow for the arrangement of hundreds or even thousands of atoms in regular, reconfigurable patterns, supporting the development of large-scale quantum processors.

Another significant benefit is the uniformity of atomic qubits. Since all atoms of a given species are identical, cold-atom platforms avoid the fabrication variability that can affect other qubit technologies. This uniformity simplifies error correction and calibration, which are critical for practical quantum computing. Furthermore, cold-atom systems can implement a variety of quantum gate mechanisms, including Rydberg interactions—where atoms are excited to high-energy states to induce strong, controllable interactions over micrometer distances. This approach enables fast, high-fidelity two-qubit gates, a cornerstone for universal quantum computation.

In 2025, several companies are advancing cold-atom quantum computing. Pasqal (France) is a leading developer, building quantum processors based on arrays of neutral atoms and focusing on both hardware and software integration. ColdQuanta (USA, now operating as Infleqtion) is another major player, developing quantum computers and quantum networking solutions using cold-atom technology. Atom Computing (USA) is notable for its large-scale, optically trapped atomic arrays and has demonstrated record-breaking coherence times. These companies are collaborating with research institutions and industry partners to accelerate the commercialization of cold-atom quantum computers.

Looking ahead, the field is expected to see rapid progress in the next few years. Advances in laser technology, vacuum engineering, and control electronics are driving improvements in qubit number, gate fidelity, and system stability. As cold-atom platforms mature, they are poised to compete with, and potentially surpass, other quantum computing modalities in scalability and performance, making them a promising candidate for practical quantum advantage in the near future.

As of 2025, the field is witnessing rapid technological progress, with several companies and research institutions advancing the scalability, coherence, and operational fidelity of cold-atom platforms. This section provides a comparative analysis of cold-atom quantum computing relative to superconducting and trapped-ion approaches, focusing on recent developments and the outlook for the next few years.

Superconducting qubits, championed by industry leaders such as IBM and Rigetti Computing, have achieved significant milestones in terms of qubit count and gate speed. These systems benefit from mature fabrication techniques and integration with existing semiconductor infrastructure. As of early 2025, superconducting processors routinely demonstrate devices with over 100 qubits, with IBM publicly outlining roadmaps toward 1,000+ qubit systems. However, superconducting qubits face challenges related to coherence times (typically in the range of tens to hundreds of microseconds) and crosstalk as systems scale.

Trapped-ion quantum computers, developed by companies such as IonQ and Quantinuum, are recognized for their long coherence times (often exceeding seconds) and high-fidelity gate operations. These systems leverage the uniformity of atomic ions and precise laser control, enabling robust error rates and all-to-all connectivity within small qubit registers. However, scaling trapped-ion systems to hundreds or thousands of qubits remains a significant engineering challenge, primarily due to the complexity of optical control and the physical footprint of the required hardware.

Cold-atom quantum computing, led by innovators such as Pasqal and Quandela (the latter also active in photonic quantum computing), utilizes neutral atoms trapped in optical lattices or tweezers. These platforms offer several intrinsic advantages: neutral atoms exhibit minimal sensitivity to environmental noise, enabling coherence times that can rival or exceed those of trapped ions. Furthermore, cold-atom systems are inherently scalable, as large arrays of atoms can be manipulated in parallel using advanced optical techniques. In 2024 and 2025, Pasqal has demonstrated programmable quantum processors with 100+ qubits, and has announced plans to scale to several hundred qubits within the next few years.
