Zero-field dipolar decoupling of color center ensembles via universal qutrit control
Antonio Verdú, Ana Teresa Gea-Caballero, Santiago Oviedo-Casado +2
Dipolar interactions are a major source of decoherence in dense ensembles of color centers in diamond. Current protocols demand using bias magnetic fields detrimental in many scena…
Ramsey correlation spectroscopy with phase cycling using a single quantum sensor
Inbar Zohar, Santiago Oviedo-Casado, Andrej Denisenko +2
Magnetic spectroscopy at the nanoscale provides unique insights into material properties and dynamics, with quantum sensors like nitrogen-vacancy (NV) centers being ideally suited…
Spectrum analysis with parametrically modulated transmon qubits
Nir Gavrielov, Santiago Oviedo-Casado, Alex Retzker
Exploring the noise spectrum impacting a qubit and extending its coherence duration are fundamental components of quantum technologies. In this study, we introduce parametric spect…
Correlated noise in Brownian motion allows for super resolution
Santiago Oviedo-Casado, Amit Rotem, Ramil Nigmatullin +2
Diffusion broadening of spectral lines is the main limitation to frequency resolution in non-polarized liquid state nano-NMR. This problem arises from the limited amount of informa…
Magnetic pulses enable multidimensional optical spectroscopy of dark states
Santiago Oviedo-Casado, František Šanda, Jürgen Hauer +1
The study and manipulation of low dipole moment quantum states has been challenging due to their inaccessibility by conventional spectroscopic techniques. Controlling the spin in s…
On the theory of excitonic delocalization for robust vibronic dynamics in LH2
Felipe Caycedo-Soler, James Lim, Santiago Oviedo-Casado +3
Nonlinear spectroscopy has revealed long-lasting oscillations in the optical response of a variety of photosynthetic complexes. Different theoretical models which involve the coher…
