Phasecraft Leads Quantum Computing Revolution with Hardware-Agnostic Algorithms and Expands into US Market
September 2, 2025
Phasecraft is advancing quantum algorithms that are hardware-agnostic, enabling practical applications across industries such as materials science, energy, and biology, with a focus on delivering real-world quantum advantage.
Founded in 2019 by Toby Cubitt, Ashley Montanaro, and John Morton, the company has expanded its research efforts, including opening a new office in Washington D.C. led by Professor Steve Flammia.
The company has raised over $50 million in total funding, with a recent round co-led by Plural, Playground Global, and Novo Holdings’ Quantum Fund.
CEO Ashley Montanaro emphasizes that Phasecraft's work is already producing meaningful results and that the company is expanding into the US market.
To support its growth, Phasecraft appointed Plural partner Ian Hogarth as chair, highlighting strategic leadership to accelerate its development.
Montanaro advocates for government support, emphasizing the importance of software and algorithms in advancing quantum technology, and encourages government as a customer to foster industry growth.
Quantum computing's core advantage lies in qubits' ability to exist in superposition, allowing simultaneous calculations crucial for solving complex problems.
Ian Hogarth from Plural underscores that Phasecraft’s hardware-agnostic approach enables it to work with multiple quantum devices, creating highly efficient algorithms for scientific and industrial challenges.
The industry context includes collaborations like IBM’s partnership with AMD to develop hybrid quantum and high-performance computing architectures, illustrating the integration of quantum tech into practical applications.
Montanaro highlights that the company is already achieving quantum advantage with algorithms that simulate complex materials and optimize energy networks, making significant industry impacts.
Phasecraft’s technology treats quantum computing as a complementary partner to classical systems, enabling previously unattainable tasks at large scales.
Ian Hogarth emphasizes the company's revolutionary impact and its partnerships with tech giants like Google and IBM to accelerate quantum device applications.
The company's hardware-agnostic technology allows it to work across various quantum devices, avoiding over-reliance on a single platform and reducing associated risks.
