About
Equal1 is an Irish quantum computing company building CMOS silicon spin qubit processors that operate at 300mK, within reach of standard industrial cryostats. Founded in 2017 out of University College Dublin and based in Dublin, the company has raised more than $90M. It has demonstrated Ireland's first quantum computer, Bell-1, a 6-qubit SiGe array, and the world's first multi-tile Quantum Controller Chip integrating Arm Cortex cores at 300mK. The 6-qubit array, fabricated on GlobalFoundries 22FDX, achieves 99.4% single-qubit fidelity with an 84ns gate and 98.4% two-qubit fidelity with a 72ns gate. Equal1 targets thousands of qubits through tile-based scaling. In February 2026, Equal1 integrated Q-CTRL's Boulder Opal Scale Up for autonomous calibration of its Bell-1 system. It also signed an MoU with NVIDIA for CUDA-Q integration with its UnityQ QSoC and partnered with TNO on scalable quantum computing research. In May 2026, Equal1 launched RacQ, a rack-mounted silicon-spin quantum computer that fits a standard 19-inch rack with a self-contained cryocooler, and showed it integrated with Dell PowerEdge servers at Dell Technologies World. The same month it announced a strategic alliance with the quantum software company Kvantify. Update 2026-05-15: Equal1's RacQ unit operates using standard power and consumes 1600W.
