Non-Markovian Effects of Two-Level Systems in a Niobium Coaxial Resonator with a Single-Photon Lifetime of 10 ms
P. Heidler, C. M. F. Schneider, K. Kustura +3
Understanding and mitigating loss channels due to two-level systems (TLS) is one of the main cornerstones in the quest of realizing long photon lifetimes in superconducting quantum…
Effective quantum dynamics induced by a driven two-level-system bath
Katja Kustura, Oriol Romero-Isart, Carlos Gonzalez-Ballestero
We derive a Born-Markov master equation describing the dissipation induced by a bath of lossy but coherently driven two-level systems (TLS) coupled to a bosonic system via Jaynes-C…
Remote Individual Addressing of Quantum Emitters with Chirped Pulses
Silvia Casulleras, Carlos Gonzalez-Ballestero, Patrick Maurer +2
We propose to use chirped pulses propagating near a bandgap to remotely address quantum emitters. We introduce a particular family of chirped pulses that dynamically self-compress…
Theory of waveguide-QED with moving emitters
Eduardo Sánchez-Burillo, Alejandro González-Tudela, Carlos Gonzalez-Ballestero
We theoretically study a system composed by a waveguide and a moving quantum emitter in the single excitation subspace, treating the emitter motional degree of freedom quantum mech…
Single-Spin Magnetomechanics with Levitated Micromagnets
Jan Gieseler, Aaron Kabcenell, Emma Rosenfeld +7
We demonstrate a new mechanical transduction platform for individual spin qubits. In our approach, single micro-magnets are trapped using a type-II superconductor in proximity of s…
Quantum Acoustomechanics with a Micromagnet
Carlos Gonzalez-Ballestero, Jan Gieseler, Oriol Romero-Isart
We theoretically show how to strongly couple the center-of-mass motion of a micromagnet in a harmonic potential to one of its acoustic phononic modes. The coupling is induced by a…
