Lancaster Physics Joins Elite €3 Million European Initiative to Revolutionize Quantum Computing Hardware
Lancaster University News
The United Kingdom’s quantum research sector, Lancaster University has been named a key partner in a prestigious €3 million European Innovation Council (EIC) Pathfinder project. The project, called “Superconducting Integrated Circuits for Scalable Quantum Systems” (Super ICQ), intends to remove the technological obstacles that stand in the way of the commercial and industrialization of quantum computers.
To lead the development of ultra-low-power electronics, the Lancaster University team led by Dr. Michael Thompson and including Professors Jonathan Prance and Yuri Pashkin has been granted a €650,000 special grant. A substantial investment in “visionary science” aimed at generating “breakthrough innovation” in the field of cryogenic electronics is represented by this financing.

The Quest for “Quantum Systems on a Chip”
A fundamental rethink of the design of quantum technology lies at the core of this research. At the moment, the qubits, the “brains” of a quantum computer, need enormous, intricate support systems in order to function. The project’s Lancaster-led component aims to show a new approach to ultra-low-power electronics capable of managing the interface, readout, and control of superconducting quantum computers.
By reducing the size of these devices, the group intends to move closer to “future quantum systems on a chip,” which would essentially transfer quantum computing from massive, lab-scale operations to a more scalable and integrated form factor.

Overcoming the “Josephson Junction” Limitation
Josephson junctions (JJs), the current building blocks of quantum electronics, must be examined in order to comprehend the relevance of this endeavor. These elements have long served as the foundation for both classical and quantum cryogenic electronics. However, the fact that conventional JJs depend on magnetic flux control or electric current is a serious engineering flaw.
That the voltage control found in the transistors that drive the contemporary semiconductor industry is significantly more practicable than this approach. Field-effect transistors, which employ small voltage signals to function efficiently, are used in everyday gadgets like laptops and cellphones. The goal of the Super ICQ project is to use Josephson field-effect transistors (JoFETs) to achieve the same degree of efficiency in the quantum world.
A New Era: From Graphene to 200 mm Wafers
The “proof-of-concept” versions of JoFETs have been documented in a variety of materials since the 1980s, the technology has infamously failed to progress to the integrated circuit (IC) level. A novel scalable production method for graphene-based JoFETs is thought to provide the answer by the Lancaster University and their collaborators.
The goal of the Super ICQ consortium is to create a 200 mm wafer platform by utilizing this graphene technology. The development of “truly scalable” superconducting integrated circuits depends on this. The researchers will construct a number of crucial elements on this platform, such as:
- Quantum-limited parametric amplifiers
- On-chip filters
- Ultra-sensitive microwave bolometers
- Voltage-tunable resonators
- Multiplexed control and readout modules.
The ability of these modules to control and read out cutting-edge superconducting qubits will be utilized to validate the new JoFET integrated circuits.

Global Competition and the EIC Pathfinder
The Lancaster team’s accomplishment in obtaining this financing demonstrates the university’s rising stature in the international research community. Over 2,000 concepts from 71 different countries were submitted in this round of the EIC Pathfinder prizes, setting a new record for interest.
Just 44 projects were chosen for financing from this enormous pool of applications. As a result, the Super ICQ project joins a select group that comprises the top 2% of creative projects globally.
In addition to funding, EIC Business Acceleration Services will provide Lancaster University researchers networking, coaching, and mentoring. This help ensures that the scientific vision is instantly turned into practice, especially in high-stakes fields like HPC and AI.
The Broader Impact: AI and Beyond
This finding has far-reaching consequences outside of the physics lab. It is anticipated that the development of scalable, gated Josephson junctions would “kick off a new era” in computing technology. JoFET technology’s incredibly quick and low-power capabilities could serve as the hardware basis for the upcoming generation of supercomputers, as artificial intelligence and high-performance computing continue to demand greater power and higher processing rates.
This project intends to facilitate the ongoing “quantum computing revolution” by producing ultra-low-power superconducting integrated circuits that are not achievable by traditional silicon electronics.
