Our focus

QuTech’s research is organized along three mission-driven science & technology roadmaps led by TU Delft Prinicipal Investigators (PIs). These roadmaps work towards the primary R&D goals of QuTech: developing scalable prototypes of quantum computers and quantum internet. In addition, QuTech has a fourth roadmap, Shared Technology Development (STD), led by TNO.

Fault-tolerant Quantum Computing

The Fault-Tolerant Quantum Computing roadmap aims for a full-stack scalable quantum computing system, including the qubit circuits, the control electronics, and the software layers such as compilers. The approach to achieve fault tolerance is based on quantum error correction, in which information is encoded redundantly enabling error detection without destroying quantum data. The qubit hardware systems are electron spins in quantum dots and superconducting quantum circuits.

Quantum Internet and Networked Computing

Our goal is to build an optically-connected network of many (small) quantum computers. Such a network enables the exchange of quantum bits between any of the connected quantum processors in order to solve problems that are intractable classically.

A quantum network in which the processors are located at different geographical locations is called a quantum Internet. Our goal is to develop the technology to enable quantum communication between any two places on earth. One application of such a quantum internet is to provide a fundamentally secure way of communication in which privacy is guaranteed by the laws of physics.

Quantum processors can also be connected into a quantum network in order to assemble a large quantum computing cluster. This approach is called networked quantum computing and offers a natural path towards scalability. Combining a quantum internet and a networked quantum computer finally allows remote users/providers to perform secure quantum computing “in the cloud”.

Topological Quantum Computing

The focus of the Topological Quantum Computing roadmap is to develop, build and demonstrate the first topologically protected quantum bit based on Majorana-bound states. We continued our efforts in combining material science, theory, and novel device design to obtain more control of the underlying constituents of the topological qubit

QuTech Shared Development

In the Shared Development roadmap, technology developments are managed for the three mission-driven roadmaps of QuTech. This roadmap facilitates the taking of quantum technology to market (technology push) and constitutes a portal to QuTech for third parties who want to access state-of-theart quantum technology (technology pull).

Quantum Software and Theory

Our goal is to develop new theory and methods to overcome the many challenges in realizing quantum technologies, and to develop useful quantum software applications.

QuTech Academy

QuTech needs great students with the drive and talent to help us accelerate the effort to build a quantum computer and a large-scale quantum internet. We work together with talented students with in-depth knowledge in the areas of both quantum physics and computer science & engineering. Find out what QuTech Academy has to offer.
