Multimode physics of the unimon circuit

Sasu Tuohino, Vasilii Vadimov, Wallace S. Teixeira +3

We consider a superconducting half-wavelength resonator that is grounded at its both ends and contains a single Josephson junction. Previously this circuit was considered as a unim…

Quantum-circuit refrigeration of a superconducting microwave resonator well below a single quantum

Arto Viitanen, Timm Mörstedt, Wallace S. Teixeira +4

We experimentally demonstrate a recently proposed single-junction quantum-circuit refrigerator (QCR) as an in-situ-tunable low-temperature environment for a superconducting 4.7-GHz…

Exceptional-point-assisted entanglement, squeezing, and reset in a chain of three superconducting resonators

Wallace S. Teixeira, Vasilii Vadimov, Timm Mörstedt +2

The interplay between coherent and dissipative dynamics required in various control protocols of quantum technology has motivated studies of open-system degeneracies, referred to a…

Pulsed multireservoir engineering for a trapped ion with applications to state synthesis and quantum Otto cycles

Wallace S. Teixeira, Matthias K. Keller, Fernando L. Semião

Conducting an open quantum system towards a desired steady state through reservoir engineering is a remarkable task that takes dissipation and decoherence as tools rather than impe…

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

Wallace S. Teixeira, Fernando L. Semião, Jani Tuorila +1

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 relati…

Inducing nontrivial qubit coherence through a controlled dispersive environment

W. S. Teixeira, F. Nicacio, F. L. Semião

We show how the dispersive regime of the Jaynes-Cummings model may serve as a valuable tool to the study of open quantum systems. We employ it in a bottom-up approach to build an e…

Coupled modes locally interacting with qubits: critical assessment of the rotating wave approximation

P. C. Cárdenas, W. S. Teixeira, F. L. Semião

The interaction of qubits with quantized modes of electromagnetic fields has been largely addressed in the quantum optics literature under the rotating wave approximation (RWA), wh…

Performance of dynamical decoupling in bosonic environments and under pulse-timing fluctuations

W. S. Teixeira, K. T. Kapale, M. Paternostro +1

We study the suppression of qubit dephasing through Uhrig dynamical decoupling (UDD) in nontrivial environments modeled within the spin-boson formalism. In particular, we address t…
