Qphox Raises €2M to Revolutionize Quantum Computing Connectivity

The Necessity of Quantum Networks

The potential of quantum computers will remain largely unrealized if these machines operate in isolation. Similar to the internet, the true power lies in interconnectedness and the ability to form a network.

Currently, however, the technological infrastructure required to effectively link these advanced devices is limited.

QphoX: Bridging the Quantum Divide

Dutch startup QphoX is addressing this challenge with a €2 million funding round, aimed at developing a “quantum modem” to facilitate communication between quantum computers.

This investment was spearheaded by Quantonation, Speedinvest, and High-Tech Gründerfonds, with additional support from TU Delft.

From University Research to Commercial Product

QphoX intends to transform a quantum modem initially developed at Delft University of Technology (TU Delft) into a commercially viable product.

This technology will enable the networking of separate processors, paving the way for quantum computers to scale beyond current limitations of tens or hundreds of qubits.

How the Quantum Modem Works

According to Simon Gröblacher, CEO and co-founder of QphoX, the quantum modem functions analogously to a classical modem.

It coherently converts electrical and microwave signals into optical signals, ensuring that quantum information remains intact during transmission.

This conversion process allows two quantum computers to communicate effectively with one another.

Compatibility Across Quantum Architectures

QphoX’s approach is designed to be versatile, accommodating various types of quantum computers.

The current focus is on the microwave spectrum, enabling compatibility with superconducting qubits, topological qubits, and others.

The system converts microwaves to optical signals, facilitating communication between different quantum platforms.

Gröblacher emphasizes that QphoX is currently the first company actively building a commercial product in this space, with competitors primarily residing within academic institutions.

Industry Perspective on Quantum Networking

Rick Hao, principal with Speedinvest’s Deep Tech team, highlights the strategic importance of QphoX’s work.

Speedinvest aims to invest in early-stage deep tech companies that are shaping the future, and QphoX is positioned to have a significant impact.

Hao anticipates rapid advancements in quantum computers over the next few years.

The Quantum Modem developed by QphoX will be instrumental in enabling the creation of quantum computers capable of demonstrating quantum advantage through the combination of separate quantum processors.
