Intrinsic Photon Loss at the Interface of Superconducting Devices
Igor Diniz, Rogério de Sousa
We present a quantum theory of dielectric energy loss arising from the piezoelectric coupling between photons and phonons in superconducting devices. Photon loss is shown to occur…
Quantum theory of an atom in proximity to a superconductor
Matthias Le Dall, Igor Diniz, Luis G. G. V. Dias da Silva +1
The impact of superconducting correlations on localized electronic states is important for a wide range of experiments in fundamental and applied superconductivity (SC). This inclu…
Microscopic origin of subthermal magnons and the spin Seebeck effect
I. Diniz, A. T. Costa
Recent experimental evidence points to low-energy magnons as the primary contributors to the spin Seebeck effect. This spectral dependence is puzzling since it is not observed on o…
Electron spin resonance detected by a superconducting qubit
Y. Kubo, I. Diniz, C. Grezes +14
A new method for detecting the magnetic resonance of electronic spins at low temperature is demonstrated. It consists in measuring the signal emitted by the spins with a supercondu…
Hybrid quantum circuit with a superconducting qubit coupled to a spin ensemble
Y. Kubo, C. Grezes, A. Dewes +15
We report the experimental realization of a hybrid quantum circuit combining a superconducting qubit and an ensemble of electronic spins. The qubit, of the transmon type, is cohere…
Storage and Retrieval of a Microwave Field in a Spin Ensemble
Y. Kubo, I. Diniz, A. Dewes +7
We report the storage and retrieval of a small microwave field from a superconducting resonator into collective excitations of a spin ensemble. The spins are nitrogen-vacancy cente…
Strongly coupling a cavity to inhomogeneous ensembles of emitters : potential for long lived solid-state quantum memories
I. Diniz, S. Portolan, R. Ferreira +3
We investigate theoretically the coupling of a cavity mode to a continuous distribution of emitters. We discuss the influence of the emitters inhomogeneous broadening on the existe…
Comment on the paper "Random Quantum Circuits are Approximate 2-designs"
Igor Tuche Diniz, Daniel Jonathan
In [A.W. Harrow and R.A. Low, Commun. Math. Phys. 291, 257-302 (2009)], it was shown that a quantum circuit composed of random 2-qubit gates converges to an approximate quantum 2-d…
