Hashberg's quantum work is software, led by co-founder Stefano Gogioso, an Oxford computer science lecturer who heads its effort on high-level quantum programming tools. What the public can see is pauliopt, an AGPL-3.0 Python library for simplifying circuits built from phase and Pauli gadgets, still described by its authors as pre-alpha. The London firm, registered in 2019, calls itself a deep-tech foundry spanning quantum, AI, finance, Web3 and gaming, and lists Spooqy as its public quantum venture.
Hashberg, based in London, is a company whose work covers quantum software and algorithms; it was founded in 2019. No project in this directory lists it yet.
