The fund has made 22 investments to date and serves as a critical early-stage capital source for UK quantum hardware spinouts with national security applications. Notable quantum portfolio companies include Oxford Ionics (a 2 million pound investment in 2023), Nu Quantum (a participant in a $60 million Series A in 2025, co-led by National Grid Partners), Phasecraft (quantum algorithms software), Riverlane (quantum error correction, with NSSIF participating in its Series B), Orca Computing (photonic quantum), PsiQuantum (photonic quantum), and Delta-g (quantum gravimetry). The fund's quantum work spans computing, sensing, communications, and post-quantum cryptography.
