Quantum mechanics is at the heart of our technology and economy - the laser and the transistor are quantum devices - but its full potential is far from being realized. Recent technological advances in optics, nanoscience and engineering allow experimentalists to create artificial structures or put microscopic and mesoscopic systems under new manipulable conditions in which quantum phenomena play a fundamental role.

Quantum technologies exploit these effects with practical purposes. The objective of Quantum Science is to discover, study, and control quantum efects at a fundamental level. These are two sides of a virtuous circle: new technologies lead to the discovery and study of new phenomena that will lead to new technologies.

Our aim is  to control and understand quantum phenomena in a multidisciplinary intersection of  Quantum Information, Quantum optics and cold atoms, Quantum Control, Spintronics, Quantum metrology, Atom interferometry, Superconducting qubits and Circuit QED and Foundations of Quantum Mechanics.

QUINST is funded in part as a “Grupo Consolidado” from the Basque Government (IT472-10, IT986-16, IT1470-22)  and functions as a network of groups with their own funding, structure, and specific goals.

Title: Optimal gates in imperfect qubits


Designing and operating a quantum computer is subject to a multitude of opposing challenges. In particular, scalable and decoherence-protected solid state quits seem to, at first glance, be very flexible and hard to control. We are going to show how optimal control theory can be used to find pulse shapes for implementing precise and fast gates. Some of these results such as the DRAG technique that avoids leakage to non-computational states can be motivated analytically in a toggling frame.
