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…
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…
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…
