Guilford life sciences firm Quantum-Si Inc. announced Tuesday it has signed a lease for a new headquarters at the Winchester Works building in New Haven.

The new location will include 65,000 square feet of office, research and development space. The lease is for 10 years. Financial terms were not disclosed.

Serial entrepreneur Jonathan Rothberg founded Quantum-Si in 2013. The company is focused on the field of proteomics, or the study of proteins. Its technology is powered by a semiconductor chip which enables single-molecule protein sequencing. The technology can be used to advance drug discovery and for diagnostics, according to the company.

Quantum-Si will begin relocating to the new headquarters in the first half of 2022. Last June, the company also announced it had leased a new product development and operations facility in San Diego, which opened this past fall. Read More

Science Park’s redevelopers landed a $2 million state grant to help clean up and demolish a derelict section of the former Winchester Arms factory — and to advance plans to create hundreds of new apartments and tens of thousands of square feet of office, lab, and retail space.

Gov. Ned Lamont made that announcement in a Thursday midday email press release about $17.9 million in newly awarded grants from the state Department of Economic and Community Development’s Brownfield Remediation Program.

One of the 40 grants included in this latest tranche is $2 million to the Science Park Development Corporation to, as the press release put it, ​“abate and demolish the former Winchester Repeating Arms Company buildings located at 275 Winchester Avenue. This will allow for the construction of residential, office, laboratory space and/or retail buildings, and public open space on the 3.11-acre site.” Read More
