Bluefors Lab

We are here to enable the quantum technology breakthrough, to support scientists and industries to go further, to allow new innovations and care for our global community. We want to support the quantum ecosystem by enabling companies to succeed with their R&D and join in contributing to the development. For this purpose, we created the Bluefors Lab services.

With the Bluefors Lab service, early phase R&D companies get easy access to a quantum measurement system, to do successful experiments proving their work. Through the Lab, customers can work with a leading technology partner and become a part of the global quantum ecosystem.

  • Measurement system for R&D

    Quick, convenient, and secure access to a millikelvin measurement system for R&D purposes.

  • Consultation and support

    Experiments consulted and supported by Bluefors.

  • Laboratory staff

    Bluefors specialist is responsible for handling and operating the dilution refrigerator measurement system.

Service features

Bluefors Lab offers companies in the early phases of R&D a way to perform quantum measurements, without the need to invest into a dilution refrigerator measurement system.

Bluefors Lab enables customers quick access to usage of a millikelvin measurement system. The focus of the lab is primarily on supporting research projects that involve electrical measurements of devices that operate at millikelvin temperatures, but the hardware and the cooling system have been chosen to enable various user applications. As such the Lab offers possibilities to test quantum applications, but also other types of research are supported.

Bluefors Lab offers a low-risk option to test solutions before investing in a permanent owned measurement system. Successful experiments can be done with a flexible service, which also provides protection for intellectual property rights.
In the Bluefors Lab customers get to work with a leading technology partner with engagement to long-term development and co-operation.

Experiments in the Bluefors Lab are supported and consulted in 2–8-week terms.

Consultation and support

Experiments at the Bluefors Lab are provided with consultation and support from Bluefors. The consultation is provided to enable the experiments to succeed. The support provided makes sure that the cryogenic system provided operates as specified.

Before any experiments begin, we consult on how they will be the most successful and how they can be done as efficiently as possible. Afterwards we help you with moving forward from the first round of experiments to the following ones.

During experiments, Bluefors Cryo Engineer is present on-site to ensure the optimal operation of systems to ensure the success of measurements being done. The laboratory staff is fully responsible for handling and operating the dilution refrigerator measurement system. This includes the following procedures:

  • Modifying the cryogenic components in the wiring channels
  • Opening and closing the cryostat shields
  • Cooldown and warm-up of the system
  • Filling in the LN2 Trap
  • Maintenance of the system and Bluefors electronics.

“Bluefors Delft Lab is an integral part of our product development process. Having a convenient and well-maintained setup at the Bluefors Lab is having measurable impact on the speed and quality of our product development.”

Delft Facility

The Bluefors Lab is situated in the Netherlands at Delft, which is home to the Quantum Delft ecosystem and the House of Quantum. The Lab is centrally located on the TU Delft campus in building 22.

The facility is easily reachable from all around Europe and the globe, as Delft is centrally located in Europe with good transit connections.

Equipment provided at Delft

The Bluefors Lab in Delft consists of a LD 400 Dilution Refrigerator System and an Orange Rack Quantum Research System. The setup was designed to include a basic suite of qubit measurement electronics to provide the needed infrastructure for quantum research.

Other hardware can be added or provided hardware replaced based on experimental needs. Additional hardware can be provided by the user or sourced by Bluefors.

Remote access is available for monitoring experiments off-site.

Bluefors LD400 system

The service includes basic operation of the LD 400 Dilution Refrigerator System. The LD 400 dilution refrigerator has best-in-class heat exchangers with superior performance. The LD400 system typically provides more than 15 µW at 20 mK on the experimental flange. In addition, it has a high cooling power of ∼0.5 mW when operated at 100 mK. This well-engineered dilution refrigerator measurement system has a clean and open design with sensitive parts well protected and out of reach for the user – minimal risk of damage during installation of experimental equipment. A single push of a button initiates a fully automated cool-down sequence from room to base temperature.

The versatile LD System gives opportunity for vast choice of options, and it can be tailored to meet various measurement setup requirements. As with all our dilution refrigerator measurement systems, the height can be easily adapted to suit your experimental requirements. The LD System features a good variety of line-of-sight access ports between Room Temperature Flange and Mixing Chamber Flange. Learn more about the system here.

Electronics rack and control computer

Quantum Research System capable of 2-qubit characterization consists of (room temperature quantum control hardware):

  • Orange Box, a lab computer with a pre-installed Docker Image of Quantify.
  • Orange Rack, a 19” stack of room temperature equipment with AWG qubit control modules which directly outputs RF signals in the range from 2-18 GHz, a readout module containing LOs, IQ mixing, and digitizers; step attenuator.
  • Orange Rack extension, for 4-terminal DC characterization capabilities.
  • Other tools may be included (as available)

Quantify is provided as the measurement and control software. Quantify is a python based open-source data acquisition platform focused on Quantum Computing and solid-state physics experiments.
