-
Quantum computing is currently limited by the inability to scale the number of qubits due to size and cooling constraints of dilution refrigerators. There is a critical need for devices that can link separate quantum processors to overcome these scalability bottlenecks.
-
QphoX develops quantum transducers that convert photons between microwave and optical frequencies using a nanomechanical resonator, enabling low-loss, high-fidelity transmission of quantum states between processors. Their Quantum Modem™ facilitates efficient quantum information transfer via optical networks, addressing the scaling challenges.
-
As quantum hardware developers like IBM approach the limits of current technology within the next 2–3 years, the need for scalable solutions like quantum interconnects becomes urgent. QphoX's technology is timely, addressing imminent bottlenecks in quantum computing scalability.
FINANCIALS
QphoX is pre-revenue but has secured significant funding, including a €2.5 million EIC grant in 2022 and an €8 million seed round in December 2023 at a €28 million pre-money valuation. They are positioned financially to execute their product development roadmap.
MARKET SIZE
The quantum computing market is projected to reach €15–20 billion by 2030, creating significant demand for scalable quantum hardware solutions such as interconnects. QPhoX aims to capture a portion of this growing market by providing essential infrastructure for quantum computing expansion.
TEAM
Led by CEO Prof. Simon Gröblacher, a full professor at TU Delft with extensive expertise in quantum optics, and co-founder Dr. Robert Stockill. The team comprises 20 full-time employees specializing in quantum transduction technology.
-
QphoX's core product is a quantum transducer that enables the conversion of quantum signals between microwave and optical frequencies, facilitating efficient information transfer between quantum processors. They plan to release optical QPU interfaces in 2025 and their Quantum Modem™ in 2027.
-
They manufacture quantum hardware for scalable all-optical readout and control of quantum processor units and for networking remotely located quantum processors via fiber-optic entanglement links. Revenue is generated through product sales and collaborations with quantum computing manufacturers.
-
Competition is limited; direct competitor Miraex has limited resources, and major companies like IBM are partnering with QphoX. QphoX is considered the strongest player in the quantum interconnect segment, with unique technology and execution capabilities.
