Bridging microwave and optical for applications in quantum sensing and quantum computing

Miraex quantum interconnects

Miraex Quantum interconnects bridge between the microwave and optical frequency domain, unlocking new applications in both quantum sensing and quantum computing

Microwave and optical signals span two different areas of the electromagnetic spectrum, each with their (dis)advantages. In the current quantum technology revolution, both frequency ranges are used – separately – to build promising applications.

At Miraex, we are building a solution to bridge these two areas, so the best of both worlds can be leveraged for new quantum applications or the improvement and scaling of existing ones.

Quantum Converters

Quantum Converters: connecting distant quantum computers together

Miraex quantum converters are designed to convert quantum states between microwave and optical photons. This is exactly what is needed to connect distant superconducting quantum computers together over a quantum network.
The energies of stationary (microwave photons) and flying (optical photons) qubits differ by five orders of magnitude, but Miraex technology can bridge this gap. They enable the transfer of quantum information over long distances between superconducting or spin chips, using classical optical telecom fiber, and thus the realization of quantum networks.

A missing link to scale up quantum computing

Microwave technologies are at the heart of some of the most promising quantum computing technologies today, and it has allowed them to reach the current (record-breaking) stage. But at the same time, the microwave domain is the biggest bottleneck for the scalability of these systems. By bridging to the optical domain where applicable, these disadvantages can be bypassed by using optical tools, e.g. for connecting quantum computers together in a cluster through optical fibers (a new quantum network). This can boost their scalability significantly.

Enabling the true potential of quantum computing

Miraex quantum converters can be used to enable such distributed quantum computing and – on a larger scale – quantum internet. Analogous to classical computers in data centers, such a quantum network can help quantum computers reach the necessary scale for practical applications, including material discovery (e.g. better batteries), drug development, logistics optimization (e.g. lower carbon footprint), financial modeling (e.g. reduced economic risk),… Quantum computing is considered to become an important tool for solving some of the most pressing issues of human civilization.

Quantum Transducers

Quantum Transducer: from microwave to optical

Miraex quantum transducers are ultra-low noise direct microwave photon to optical photon transducers. They enable microwave single-photon detection and allow to extract more precise information about the physical quantity measured.
Our quantum-enhanced sensor technology can surpass existing technologies in terms of sensitivity, electromagnetic immunity and compactness. The use of miniaturized, microscale-sized sensing devices leads to higher spatial resolution and makes quantum sensors suitable for integrated solutions in small and flexible systems.

Quantum-enhanced sensing: detect the undetectable

Quantum properties of electromagnetic fields offer the possibility of breaking classical limits in many domains, in particular in that of remote sensing. It offers an impressive enhancement of sensitivity, especially when detecting targets with very small radar cross-sections and weak returning echoes.
Our quantum transducers can boost the sensitivity of remote sensing to an unprecedented level, potentially excluding the possibility of having stealth targets and overcoming jamming techniques.
