Rigetti Computing (RGTI) is stepping up its game in quantum hardware, teaming up with Dutch startup QphoX and the UK’s National Quantum Computing Centre (NQCC) to tackle one of the industry’s biggest headaches: heat.
What is the Actual News About?
The trio has secured a multinational grant to develop and scale a new way to read superconducting qubits—using light, not wires. The method, known as optical readout, converts microwave signals from quantum chips into optical pulses, which can be carried through thin fiber instead of bulky coaxial cables. This breakthrough promises to dramatically reduce heat buildup inside quantum systems, which must operate at near absolute zero.
Rigetti will integrate this technology into its 9-qubit Novera processor, with testing planned at the NQCC. If successful, it could help the company pack more qubits into its machines and move closer to the holy grail of fault-tolerant quantum computing.
“This is an innovative solution to a well-known scaling challenge,” said Rigetti CEO Dr. Subodh Kulkarni. “Our modular system architecture allows us to bring in cutting-edge tech from partners like QphoX to accelerate progress.”
Timing Is Everything
While the total value of the grant hasn’t been disclosed, similar European programs often range between £3 and £10 million. For Rigetti, this is a welcome boost—and crucially, it doesn’t dilute shareholders.
The news lands at a sensitive time for Rigetti. The stock has lost 35% of its value since the beginning of the year. In the meantime, investors have been watching closely for signs of real technical traction—and this project could be one.
With big names like IBM (IBM) and Google (GOOG) setting the pace in quantum computing, Rigetti has to carve out its own path. By betting on open architecture and deep partnerships, the company aims to punch above its weight. The new optical readout initiative won’t move markets overnight, but it gives Rigetti a fresh narrative—and potentially, a powerful new tool in its quantum toolbox.
Is RGTI Stock a Good Buy?
Currently, Riggeti has the firm belief of Wall Street analysts, sporting a Strong Buy rating. The average price target for RGTI stock is $15.50, implying a 58.41% upside potential.
