Optimizing Pump Conditions of Parametric Amplifiers for Fast Multiplexed Readout of Superconducting Qubits
Jeongwon Kim, Wei Dai, Omrie Ovdat +3
Low-noise parametric amplifiers are widely used as the first-stage amplifier in qubit readout chains. The performance of parametric amplifiers depends sensitively on the choice of…
Spectroscopy and Coherence of an Excited-State Transition in Tm:YAlO at Telecommunication Wavelength
Luozhen Li, Akshay Babu Karyath, Julien Bertrand +12
We characterize spectroscopic and coherence properties of the 1451.37 nm excited-state zero-phonon line (ZPL) between the and the manifolds of a thulium-dop…
Qubit teleportation between a memory-compatible photonic time-bin qubit and a solid-state quantum network node
Mariagrazia Iuliano, Marie-Christine Slater, Arian J. Stolk +8
We report on a quantum interface linking a diamond NV center quantum network node and 795nm photonic time-bin qubits compatible with Thulium and Rubidium quantum memories. The inte…
Quadratic Zeeman Spectral Diffusion of Thulium Ion Population in a Yttrium Gallium Garnet Crystal
Jacob H. Davidson, Antariksha Das, Nir Alfasi +3
The creation of well understood structures using spectral hole burning is an important task in the use of technologies based on rare earth ion doped crystals. We apply a series of…
Optically detected flip-flops between different spin ensembles in diamond
Sergei Masis, Sergey Hazanov, Nir Alfasi +2
We employ the technique of optical detection of magnetic resonance to study dipolar interaction in diamond between nitrogen-vacancy color centers of different crystallographic orie…
Multiphoton resonances in nitrogen-vacancy defects in diamond
Sergei Masis, Nir Alfasi, Roei Levi +2
Dense ensembles of nitrogen vacancy (NV) centers in diamond are of interest for various applications including magnetometry, masers, hyperpolarization and quantum memory. All of th…
Optical detection of paramagnetic defects in diamond using off-resonance excitation of NV centers
Nir Alfasi, Sergei Masis, Oleg Shtempluck +1
In this work we use fluorescence from nitrogen-vacancy defects in diamond to detect and explore other paramagnetic defects in the diamond, such as P1 defects, which are commonly un…
Exploring the nonlinear regime of light-matter interaction using electronic spins in diamond
Nir Alfasi, Sergei Masis, Roni Winik +4
The coupling between defects in diamond and a superconducting microwave resonator is studied in the nonlinear regime. Both negatively charged nitrogen-vacancy and P1 defects are ex…
Enhanced concentrations of nitrogen-vacancy centers in diamond through TEM irradiation
D. Farfurnik, N. Alfasi, S. Masis +6
The studies of many-body dynamics of interacting spin ensembles, as well as quantum sensing in solid state systems, are often limited by the need for high spin concentrations, alon…
Diamond Magnetometry of Meissner Currents in a Superconducting Film
Nir Alfasi, Sergei Masis, Oleg Shtempeluk +2
We study magnetic field penetration into a thin film made of a superconducting niobium. Imaging of magnetic field is performed by optically detecting magnetic resonances of negativ…
Diffusion in the Presence of Scale-Free Absorbing Boundaries
Nir Alfasi, Yacov Kantor
Scale-free surfaces, such as cones, remain unchanged under a simultaneous expansion of all coordinates by the same factor. Probability density of a particle diffusing near such abs…
