Equal1 unveils rack-mounted silicon-spin quantum computer, RacQ

Irish quantum computing startup Equal1 has unveiled RacQ, a rack-mounted silicon-spin quantum computer powered by UnityQ, the company’s CMOS quantum system-on-chip.

In a statement, Equal1 said RacQ builds on its earlier Bell-1 system, extending the company’s quantum technology into a standard data center form factor designed for hybrid quantum-classical computing.

Described by the company as a world first, Equal1 said the system has been designed to fit inside a conventional 19-inch rack, meaning it can be plugged into existing data centers using only a standard 1.6kW power socket.

Weighing 400kg (882lb), RacQ also features an integrated, self-contained, closed-cycle cryocooler that maintains an internal temperature of 0.3 Kelvin (-272.85°C/-459.13°F) without external infrastructure.

Equal1 said it will demonstrate how RacQ can be deployed in a data center environment by integrating it with a Dell PowerEdge R770 server and a PowerSwitch networking environment at Dell Technology’s annual conference in Las Vegas next week.

“For nearly every organization, quantum computing remains out of reach, confined to labs,” says Jason Lynch, CEO of Equal1. “We’re changing that. We are putting quantum inside the rack so customers can roll it in, plug it in, and begin running hybrid quantum–classical workloads in days, using the infrastructure they already own.”

Spun out of University College Dublin in 2018, Equal1 has been developing a quantum processor using silicon spin qubits, a technology that has been co-developed by TNO and Delft University of Technology.

The company unveiled its Bell-1 quantum server in March 2025. Named after John Stewart Bell, the Belfast-born physicist whose work focused on quantum mechanics, Bell-1 is a silicon-based offering that operates at 1,600W and slots “seamlessly” into existing data centers and high-performance computing (HPC) environments by plugging into standard electrical sockets.

In January 2026, the company announced it had raised $60 million in a funding round led by the Ireland Strategic Investment Fund.
