New Haven, Connecticut-based Quantum Circuits has raised $26.5 million in an extended Series-B funding round.

Led by Sequoia Capital Partners, the round brings the total raised by the quantum computing company since it was established in 2015 to $84m.

Founded by two Yale University scientists and now with a staff of around 50, Quantum Circuits is working to develop quantum computing systems based on superconducting technology with a proprietary approach to error correction.

According to a report in the Hartford Business Journal (HBJ), Quantum Circuits is now looking to transition into the engineering stage of testing, with newly appointed president and CEO Ray Smets telling the news outlet that this year he anticipates the company will start selling its quantum computing capabilities via a cloud service.

In addition to supporting Quantum Circuits’ long-term goal of selling quantum computers to customers, the company said it will use the funds to expand its workforce by 50 percent and grow its footprint in New Haven. Its current lab space is situated in Yale’s Science Park.

Commenting on the strength of quantum computing talent in Connecticut – which has recently sought to establish a quantum technology business corridor dubbed QuantumCT – Smets told HBJ that there are no two companies alike as everyone is approaching the challenge from a different angle.

“There’s going to be multiple winners. Different quantum computers may solve different kinds of problems. We intend to be one of the winners,” he said.

Smets added that it is his aim to eventually take the company public.
