Quantum computing has tremendous potential to overcome some of the fundamental limitations present in classical information processing. Yet, today's technological limitations in the quality and scaling prevent exploiting its full potential. Quantum c

Tunable coupling of superconducting qubits has been widely studied due to its importance for isolated gate operations in scalable quantum processor architectures. Here, we demonstrate a tunable qubit-qubit coupler based on a floating transmon device

Efficient classical simulation of open bosonic quantum systems

Autor: Mäkinen, Akseli, Ikonen, Joni, Aoki, Takaaki, Tuorila, Jani, Matsuzaki, Yuichiro, Möttönen, Mikko

We propose a computationally efficient method to solve the dynamics of operators of bosonic quantum systems coupled to their environments. The method maps the operator under interest to a set of complex-valued functions, and its adjoint master equati

Assessment of weak-coupling approximations on a driven two-level system under dissipation

Autor: Teixeira, Wallace S., Semião, Fernando L., Tuorila, Jani, Möttönen, Mikko

Publikováno v: New J. Phys. 24, 013005 (2022)

The standard weak-coupling approximations associated to open quantum systems have been extensively used in the description of a two-level quantum system, qubit, subjected to relatively weak dissipation compared with the qubit frequency. However, rece

System-Environment Correlations in Qubit Initialization and Control

Autor: Tuorila, Jani, Stockburger, Jürgen, Ala-Nissila, Tapio, Ankerhold, Joachim, Möttönen, Mikko

Publikováno v: Phys. Rev. Research 1, 013004 (2019)

The impressive progress in fabricating and controlling superconducting devices for quantum information processing has reached a level where reliable theoretical predictions need to account for quantum correlations that are not captured by the convent
