Novel materials and algorithms for quantum technologies
The enormous advancements in the ability to detect and manipulate single quantum states have lead to the emerging field of quantum technologies. Among these, quantum computation is the most far-reaching and challenging, aiming to solve problems that the cl ...
EPFL2022Variational dynamics as a ground-state problem on a quantum computer
Giuseppe Carleo, Stefano Barison, Filippo Vicentini
We propose a variational quantum algorithm to study the real-time dynamics of quantum systems as a ground -state problem. The method is based on the original proposal of Feynman and Kitaev to encode time into a register of auxiliary qubits. We prepare the ...
