Spin amplification in realistic systems
Ivan Iakoupov, Victor M. Bastidas, Yuichiro Matsuzaki +2
Spin amplification is the process that ideally increases the number of excited spins when one of them is excited initially. We show that by applying optimal control techniques to d…
Saturable Purcell filter for circuit quantum electrodynamics
Ivan Iakoupov, Kazuki Koshino
We consider a typical circuit QED setup where an artificial atom encodes a qubit and is dispersively coupled to a measurement resonator that in turn is coupled to a transmission li…
Sequential nonabsorbing microwave single-photon detector
Ivan Iakoupov, Yuichiro Matsuzaki, William J. Munro +1
We propose a nonabsorbing microwave single-photon detector that uses an artificial atom as a coherent interaction mediator between a traveling photon and a high-Q resonator, fully…
Controlled-phase gate for photons based on stationary light
Ivan Iakoupov, Johannes Borregaard, Anders S. Sørensen
We propose a method to induce strong effective interactions between photons mediated by an atomic ensemble. To achieve this, we use the so-called stationary light effect to enhance…
Dispersion relations for stationary light in one-dimensional atomic ensembles
Ivan Iakoupov, Johan R. Ott, Darrick E. Chang +1
We investigate the dispersion relations for light coupled to one-dimensional ensembles of atoms with different level schemes. The unifying feature of all the considered setups is t…
Photonic Controlled-Phase Gates Through Rydberg Blockade in Optical Cavities
Sumanta Das, Andrey Grankin, Ivan Iakoupov +7
We propose a novel scheme for high fidelity photonic controlled phase gates using Rydberg blockade in an ensemble of atoms in an optical cavity. The gate operation is obtained by f…
An efficient quantum memory based on two-level atoms
Ivan Iakoupov, Anders S. Sørensen
We propose a method to implement a quantum memory for light based on ensembles of two-level atoms. Our protocol is based on controlled reversible inhomogeneous broadening (CRIB), w…
