About QUINST

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: "Theoretical study on fast and accurate quantum controls and applications: spin-selective electron transfer in quantum dots, and single photon source in cQED system"  

 

Abstract:

We discuss the engineering of high-fidelity fast two-qubit gate operations for information processing using STIRAP and shortcuts to adiabaticity.  In addition, we report the adiabatic and nonadiabatic creation of single microwave photon in a circuit QED system, which paves the way to arbitrary wave form engineering on-chip microwave photon source. We introduce two different kinds of on-chip microwave photon sources with high efficiency.
