IBM is planning another building at its quantum campus in Poughkeepsie, New York.

As reported by local publication Midhudson News, Big Blue has filed to develop a 511,000 sq ft (47,475 sqm) quantum computing facility at its existing campus.

IBM will demolish two existing buildings with a total floorspace of 161,000 sq ft (14,955 sqm) to establish the new center, which will be used to manufacture and assemble its next-generation Starling quantum systems.

In June last year, IBM updated its quantum computing roadmap and said that it plans to deliver the Starling computer by 2029. Starling will be a large-scale quantum computer that is expected to perform 20,000 times more operations than today’s quantum computers. Plans for it to be housed at the Poughkeepsie campus were announced at the same time.

Starling will reportedly be able to run 100 million quantum operations using 200 logical qubits. It will be a precursor to Blue Jay, another quantum system capable of executing 1 billion quantum operations over 2,000 logical qubits. Both use the company's hexagonal design - Starling comprising six connected hexagonal quantum systems, while Blue Jay will have 11.

The new building could bring the campus's footprint up to 3.9 million sq ft (362,320 sqm) across 45 buildings. The building will create 200 jobs once operational.

The new building will have a maximum height of 40 feet, and will be partially below ground to support the needed quantum cooling infrastructure without exceeding height limits.

“This represents one of the most significant investments in Dutchess County’s history, and the largest at IBM’s Poughkeepsie campus in more than four decades,” said county executive Ron Hicks. “When IBM launched the System/360 in Poughkeepsie in 1964, it helped transform computing and reshape business, science, government, and the technology industry around the world. More than 60 years ago, IBM placed Poughkeepsie on the global stage. Today, it is poised to do so once again.”

While the facility will increase the power draw of the campus, IBM representatives have said that existing infrastructure should be sufficient through 2030.

IBM now needs to get independent verification from Central Hudson on grid capacity and how the grid will be impacted beyond 2030, must conduct traffic, noise, and visual impact studies, and secure amendments to existing state DEC environmental permits. IBM will next present the project in May with updated site plans and the necessary studies.

IBM deployed additional quantum computers at its Poughkeepsie campus in September 2024. At the time, the company said the site was home to the highest number of utility-scale quantum computers at a single location in the world.
