Floquet Topological Frequency-Converting Amplifier
Adrian Parra-Rodriguez, Miguel Clavero-Rubio, Philippe Gigon +3
We introduce a driven-dissipative Floquet model in which a single harmonic oscillator, with both frequency and decay rate modulated, realizes a non-Hermitian synthetic lattice with…
Decoherence-free subspaces in the noisy dynamics of discrete-step quantum walks in a photonic lattice
Rajesh Asapanna, Clément Hainaut, Alberto Amo +1
We study the noisy dynamics of periodically driven, discrete-step quantum walks in a one-dimensional photonic lattice. We find that in the bulk, temporal noise that is constant wit…
Observation of extrinsic topological phases in Floquet photonic lattices
Rajesh Asapanna, Rabih El Sokhen, Albert F. Adiyatullin +4
Discrete-step walks describe the dynamics of particles in a lattice subject to hopping or splitting events at discrete times. Despite being of primordial interest to the physics of…
Topological Josephson parametric amplifier array: A proposal for directional, broadband, and low-noise amplification
Tomás Ramos, Álvaro Gómez-León, Juan José García-Ripoll +2
Low-noise microwave amplifiers are crucial for detecting weak signals in fields such as quantum technology and radio astronomy. However, designing an ideal amplifier is challenging…
A perspective on scaling up quantum computation with molecular spins
S. Carretta, D. Zueco, A. Chiesa +2
Artificial magnetic molecules can contribute to progressing towards large scale quantum computation by: a) integrating multiple quantum resources and b) reducing the computational…
Topological phases in adiabatic and nonadiabatic driven systems
Álvaro Gómez-León, Gloria Platero
In this work we study the geometrical and topological properties of non-equilibrium quantum systems driven by ac fields. We consider two tunnel coupled spin qubits driven by either…
