Scaling up Quantum Processors to Large Scale Quantum power !


Use Microwave Error Correction to cancel Noise and improve your qubits readout fidelity.

Perform real-time embedded calibration to optimize QPU availability and track system evolution.


Our Concept

Our Energy efficient products roadmap is unique as it allows to control One Million qubits & gates.

  • Reduce your cryostat passive heat load with optical fibers instead of coaxial or ribbon cables
  • Remove all Attenuators generating a useless active heat load
  • Reduce the amount of electronics you need to control your qubits, multiplexing is Key

Hardware Qubit control

  • Qubit Controller

    The RF signal generation chassis will allow you to control the Qubits in your QPU in two different modes: "Direct" Control or "Multeplexing" Control Mode.

  • RF Over Fiber

    The Optical Extenssion chassis for converting the RF signals over Optical Fibers, conserving the integrity signals genrated on two methods (Single or Multiplexed mode) RF signals with the VIQTHOR's Optical/RF converter module through the Cryostat.

Our Photonics Quantum Control System is based on building blocks which are available to fit your needs.

From Firmware IP licence to Full Hardware system control we can help you scale up your QPU in size and performance.

Our Multiplexing Skill

Our Multiplexing VIQTHOR’s Techology is a method to control the large-scale quantum computers. This solution features an unmatched density of channels and is easily expandable to cost-efficiently control even the largest quantum processors available.

Scale up your quantum computer with reduction of cablings add our optical fibers solutions to distubutes many controls signals at your Quantum Processor.

All our solutions preserve all integrity of properties of the signals transmitted, to guarantee the best performance.

Our Technology

Qubit control signals transport through Photonics, Microwaves and Signal Processing

Microwaves : Low-Noise up & down converters to dozens of GHz.

Processing digitally very high frequency is often a tough technical challenge and using a frequency translating device can be a game changer for the budget and the accuracy of the signals.

Our Up and Down converters allows you to use most of the sub-6 GHz products at a much higher frequency, potentially up to 140 GHz.

Photonics : Low-Noise RF over Fiber, Cryogenic Photonics

Coaxial cables are lossy, big, draw heat and have limited bandwidth; this is way optical fibers are so popular in the telecom industry. Take leverage of this mature technology to connect your processor, being at room temperature or down-to cryogenic ones at 10mK.

We have connectorized solutions to transmit up to 40 simultaneous Microwave signals over fiber to your QPU.

Signal Processing : up to 3 GHz of instantaneous Bandwidth with up to 12 GHz DACs and ADCs interfaces connected to FPGAs based pulse processor
