WE ARE QUANTUM DESIGNERS

// Physics + Engineering

Building a Quantum Computer is 30% Physics and 70% Engineering

// 01 CHIP LEVEL

Create a high-grade cat-qubit chip

Design

//

From Electronic Design Automation to Machine Learning, our researchers design the best Alice & Bob chip.

//

The Chip design team uses simulation software to imagine how new generation of quantum chips could look.

//

They continuously test and improve their circuits working hand in hand with the Nano-fabrication team.

Nano-fabrication

//

This is where the chip is born. The Nano-fabrication team operates at the limits of modern engineering.

//

The chip is crafted according to design at a scale of just a few nanometers from superconducting materials.

//

Advanced lithography and precision instruments enable the refinement to Alice & Bob’s standards.

Designing new quantum circuits

This is the very heart of the system – how we create cat qubits. A lot of smarts are packed into an Alice & Bob quantum circuit. Here are some previous and current circuit designs.

IN DESIGN

// 02 SYSTEM LEVEL

Build a system to operate the quantum chip

System design and architecture

//

The full system is built around a powerful fridge where the chip lives in a vacuum, safe and sound.

//

Cooling technology maintains the temperature at 10 mK. This is the coldest place in the Universe.

//

Although the "chandelier" is often the star, all elements require intricate planning and designing.

Build and install

//

Over 7000 different components are assembled to build an Alice & Bob quantum computer.

//

Our engineers work with many partners such as Bluefors and QM to co-develop our systems.

//

Cabling and the routing of utilities such as cooling water and good old electricity are key.

Run and operate

//

Our quantum computers are all living experiments, prototypes which constantly evolve.

//

At our facilities we test new chips, set-ups, machinery and processes on a daily basis.

//

We monitor temperature, humidity, vibration, magnetic field and more all the time.

// 03 SOFTWARE LEVEL

Build a software architecture to communicate with the chip

Last but not least an operating system enables communication with and control of the chip. The different software bricks are built to send signals to it, measure it and read its results. Here is a simplified view of the different steps from a user's initial question to a quantum computer's answer.

// STEP 1

The science question

Everything starts with a science question. A physicist asks: why does some matter behave in this particular way? We break down this question into a series of mathematical steps.

// STEP 2

Algorithm design

Now we write mathematical steps as quantum logical operations. In a universal fault-tolerant architecture gates are error-corrected and any algorithm can be run on the gate-set.

engsteps2

// STEP 3

Compilation

From the high-level logical operations we travel down the software layers by breaking down quantum gates into microwave pulses to control each qubit.

engsteps3

// STEP 4

The answer

When all pulses are applied, the qubits can be measured. By repeating this process we obtain a range of probability. These can be used in turn to answer the original question.

// Behind the Tech

Meet the people designing the future of quantum computing one qubit at a time.
