Efficient quantum computation in a network with probabilistic gates and logical encoding
Johannes Borregaard, Anders S. Sørensen, Ignacio Cirac +1
A new approach to efficient quantum computation with probabilistic gates is proposed and analyzed in both a local and non-local setting. It combines heralded gates previously studi…
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…
Figures of merit for quantum transducers
Emil Zeuthen, Albert Schliesser, Anders S. Sørensen +1
Recent technical advances have sparked renewed interest in physical systems that couple simultaneously to different parts of the electromagnetic spectrum, thus enabling transductio…
Multi-partite entanglement detection with non symmetric probing
Luca Dellantonio, Sumanta Das, Jürgen Appel +1
We show that spin squeezing criteria commonly used for entanglement detection can be erroneous, if the probe is not symmetric. We then derive a lower bound on squeezing for separab…
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…
Interfacing superconducting qubits and single optical photons using molecules in waveguides
Sumanta Das, Vincent E. Elfving, Sanli Faez +1
We propose an efficient light-matter interface at optical frequencies between a single photon and a superconducting qubit. The desired interface is based on a hybrid architecture c…
