Scalable Quantum Computing Hardware

Universal Quantum will build a scalable quantum computer, allowing the QEC Project consortium to take a big step towards unlocking the full commercial potential of quantum computers.


Scalable quantum computing hardware is vital to tackle real-world problems and unlock the true potential of this technology. The QEC project will use the scalable quantum computing blueprint pioneered by Universal Quantum to make a scalable quantum computer. This architecture uses individually charged atoms – ions – as its qubits. 


Qubits are naturally identical, well isolated from the environment, and easily controllable.


A microchip ideally suited for error correction - enables ion qubits to be moved around for full connectivity


This high connectivity may allow more efficient quantum error correction methods to be used. 

Universal Quantum’s scalable approach to building quantum computers overcomes many barriers to large-scale quantum computing.

This unique design does not require cooling to near absolute zero as with superconducting quantum computers


Instead of complex laser-based technology, quantum information is processed by applying voltages to a microchip analogous to a classical transistor


With a single wafer holding just a few thousand qubits at most, modularity is critical to scale quantum computers

This design uses ultra-fast electric field connections as compared to complex photonic interconnects between quantum computing modules. These modules feature a fully connected trapped ion qubit system and integrated qubit control technology.


These modules feature a fully connected trapped ion qubit system and integrated qubit control technology. This capitalizes on the wealth of expertise that has come out of the development of the silicon microchips used in conventional computers.


To ensure successful long-term and zero-intervention operation of the Quantum Error Corrected Quantum Computer, it must be installed and operated in Extreme High Vacuum (XHV) vacuum system which requires solutions to unique elements such as:

  • compatible material and sealing selection,

  • zero vibrations,

  • specific gas loads,

  • magnetic field suppression and stability,

  • cryogenic interfaces

  • passive pumping configuration with a minimum footprint to control leaks, outgassing and long term permeation

  • maximum allowable temperature during baking to be <120° C.

The Quantum Computer at the heart of the QEC project will use trapped-ion technology which presents specific vacuum requirements and challenges.
Edwards takes the responsibility for the design, assembly, optimisation and commissioning of the XHV system.
