Important announcement

Dear visitor,

Please note that this OpenCourseWare platform will be replaced at the end of 2026 by a new platform (under the same url ocw.tudelft.nl).

Courses and their contents that are currently available the platform will partly be migrated. URL’s for this content will change and content might be unavailable for some time. In addition, some courses will not be available anymore.

If you are linking to specific courses on this platform (for instance for your students), please take timely measures to avoid problems with access. Possible actions are:

  • Download the materials to your local platform (laptop, server)
  • For educators only (including TU Delft lecturers): Contact us at ocw@tudelft.nl and inform us what course you are using in what context (institute, program, period of use, number of students). We will research (in collaboration with the authors of the course) and decide if we will migrate the course, and if yes, can supply you with a new url.

Thank you.

Home Courses The Building Blocks of a Quantum Computer: Part 2 Course materials Lectures 1.3.1 Interfacing qubits with classical systems

1.3.1 Interfacing qubits with classical systems

Course subject(s) Module 1. Introduction to the building blocks of a quantum computer

In the next two video lectures, Fabio will talk about the layer that is closest to the qubits: the quantum-to-classical interface. How do we realise the readout of qubits and what are the associated challenges?

Main takeaways

  • In order to control the qubits of the quantum processor, we need an electronic interface to perform the operations on the qubits and read out the states of the qubits.
  • Custom-built electronic components built to operate at cryogenic temperatures are needed to build a scalable quantum computer.
  • The components of the electronic interface need to be placed as close as possible to the quantum processor.
  • To make it possible to build a scalable quantum computer we need to take performance, power dissipation, and cryogenic operation into account when building the electronic interface.
