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

Quantum behavior of a superconducting Duffing oscillator at the dissipative phase transition

Autor: Chen, Qi-Ming, Fischer, Michael, Nojiri, Yuki, Renger, Michael, Xie, Edwar, Partanen, Matti, Pogorzalek, Stefan, Fedorov, Kirill G., Marx, Achim, Deppe, Frank, Gross, Rudolf

Understanding the non-deterministic behavior of deterministic nonlinear systems has been an implicit dream since Lorenz named it the "butterfly effect". A prominent example is the hysteresis and bistability of the Duffing oscillator, which in the cla

The scattering coefficients of superconducting microwave resonators: II. System-bath approach

Autor: Chen, Qi-Ming, Partanen, Matti, Fesquet, Florian, Honasoge, Kedar E., Kronowetter, Fabian, Nojiri, Yuki, Renger, Michael, Fedorov, Kirill G., Marx, Achim, Deppe, Frank, Gross, Rudolf

We describe a unified quantum approach for analyzing the scattering coefficients of superconducting microwave resonators with a variety of geometries. We also generalize the method to a chain of resonators with time delays, and reveal several transpo

Photon-number-dependent effective Lamb shift

Autor: Viitanen, Arto, Silveri, Matti, Jenei, Máté, Sevriuk, Vasilii, Tan, Kuan Yen, Partanen, Matti, Goetz, Jan, Grönberg, Leif, Vadimov, Vasilii, Lahtinen, Valtteri, Möttönen, Mikko

Publikováno v: Phys. Rev. Research 3, 033126 (2021)

The Lamb shift, an energy shift arising from the presence of the electromagnetic vacuum, has been observed in various quantum systems and established as the part of the energy shift independent of the environmental photon number. However, typical stu

Quantum Fourier Transform in Oscillating Modes

Autor: Chen, Qi-Ming, Deppe, Frank, Wu, Re-Bing, Sun, Luyan, Liu, Yu-xi, Nojiri, Yuki, Pogorzalek, Stefan, Renger, Michael, Partanen, Matti, Fedorov, Kirill G., Marx, Achim, Gross, Rudolf

Quantum Fourier transform (QFT) is a key ingredient of many quantum algorithms where a considerable amount of ancilla qubits and gates are often needed to form a Hilbert space large enough for high-precision results. Qubit recycling reduces the numbe
