Neutral Atoms

Neutral atoms are atoms with balanced positive and negative charge. Every atom of the same isotope is identical by nature, giving quantum systems a uniform foundation that does not need to be fabricated qubit by qubit. Infleqtion uses the internal states and motion of atoms for quantum computing, precision timing, spectrum sensing, inertial sensing, and gravity sensing.

In a neutral atom quantum computer, lasers cool atoms to near absolute zero and optical tweezers hold them in programmable arrays. Quantum information is encoded in selected atomic energy levels. Lasers then control individual atoms, excite them into Rydberg states so they can interact, and read the result through light emitted by the atoms.

Neutral atoms combine natural uniformity, long coherence, optical control, and flexible array geometry. Large numbers of atoms can be arranged and repositioned without manufacturing each qubit as a separate device. For Infleqtion, these characteristics support a common technology base for both quantum computing and multiple forms of quantum sensing.

No. Neutral atoms are laser-cooled to extremely low temperatures, and the surrounding system can operate at room temperature. Infleqtion’s neutral atom architecture does not require large cryogenic refrigeration systems used by some other quantum-computing approaches. The system still requires precision lasers, vacuum technology, controls, electronics, and software.

Different atomic properties enable different sensing functions. Stable atomic transitions provide precise timing references; highly excited Rydberg atoms respond to radio-frequency fields; and atom interferometry measures acceleration, rotation, gravity, and gravity gradients. Infleqtion applies these capabilities to optical clocks, spectrum sensing, navigation, and geophysical and space-based measurement programs.

One neutral atom platform means Infleqtion reuses core capabilities across several product categories. Those capabilities include vacuum systems, atom sources, lasers, photonics, electronics, controls, calibration, and software. The atoms are organized and measured differently for each application, but shared technology and engineering expertise can support computing, timing, spectrum sensing, and inertial and gravity sensing.

Neutral atom systems can scale by arranging many identical atoms in optical-tweezer arrays and reconfiguring their positions for computation. Atom movement can create flexible connectivity between qubits, while integrated optical control can address larger arrays. Practical scale also depends on gate performance, error correction, control systems, software, and reliable system integration, not physical-qubit count alone.
