Quantum computing

The quantum revolution

While conventional computers use binary bits (1 and 0) as the process for calculation, a quantum computer uses quantum bits, knows as qubits. These operate according to 2 key principles of quantum physics: superposition and entanglement. Superposition means that each qubit can represent both a 1 and a 0 at the same time, as well as many other states in between. Qubits exhibit properties of quantum entanglement – a phenomenon that means pairs, or groups, of particles, cannot be measured or described independently of each other. Measuring a single qubit in an entangled group instantly determines the state of other particles in the group. This holds true even if the particles are taken a virtually unlimited distance apart.

Large-scale quantum computers would theoretically be able to solve certain classes of problems much faster than a classical computer. Moreover, quantum computers can solve problems that are not feasible on classical computers because of their superposition characteristic. The potential future impact of quantum computing on the current classical computing is enormous. The quantum revolution goes very fast, and the Netherlands is a frontrunner in technology development. We are getting in the ‘quantum ready phase’, so we need to be prepared for the ‘quantum advantage phase’ where quantum technology will be applied towards mainstream.

Why quantum computing at SURF?

We aim to support Dutch researchers to take early and competitive advantage of quantum computing developments and facilities while these become available. Furthermore, we want to

• Understand the applicability for scientific applications
• Stimulate and support the development of quantum applications
• Understand the required expertise and tools to ‘transform’ regular applications into quantum applications
• Support access and use of quantum simulators as well as physical quantum computers (in the future).

Activities

• Exploring the applicability in scientific problems with use cases: we are stimulating and supporting use cases on promising quantum application areas relevant to our members. SURF will evaluate potential applications, required efforts, methods and tools to build joined expertise, examples and best practices.
