Photon Sorting with a Quantum Emitter
Kasper H. Nielsen, Etienne Corminboeuf, Benedikt Tissot +8
High-quality photonic Bell state measurements (BSMs) enable scalable universal quantum computing and long distance quantum communication. However, when implemented with linear opti…
Remotely Preparing Many Qubits with a Single Photon
Tzula B. Propp, Benedikt Tissot, Anders S. Sørensen +1
A single photon in a superposition of modes naturally encode a -dimensional quantum system, a so-called qudit. We show that such superpositions can be leveraged to achieve a…
High fidelity photon-photon gates by scattering off a two-level quantum emitter
Love A. Pettersson, Victor R. Christiansen, Klaus Mølmer +1
We present a scheme for implementing a high-fidelity non-linear phase shift on a photonic state. The scheme is based on repeated scattering off a two-level quantum emitter embedded…
Satellite-assisted quantum communication with single photon sources and atomic memories
V. Domínguez Tubío, M. Badás Aldecocea, J. van Dam +2
Satellite-based quantum repeaters are a promising means to reach global distances in quantum networking due to the polynomial decrease of optical transmission with distance in free…
Deterministic photon source of genuine three-qubit entanglement
Yijian Meng, Ming Lai Chan, Rasmus B. Nielsen +10
Deterministic photon sources allow long-term advancements in quantum optics. A single quantum emitter embedded in a photonic resonator or waveguide may be triggered to emit one pho…
Heralded quantum gates with integrated error detection in optical cavities
J. Borregaard, P. Kómár, E. M. Kessler +2
We propose and analyze heralded quantum gates between qubits in optical cavities. They employ an auxiliary qubit to report if a successful gate occurred. In this manner, the errors…
Near Heisenberg limited atomic clocks in the presence of decoherence
Johannes Borregaard, Anders S. Sørensen
The ultimate stability of atomic clocks is limited by the quantum noise of the atoms. To reduce this noise it has been suggested to use entangled atomic ensembles with reduced atom…
Photon sorters and QND detectors using single photon emitters
D. Witthaut, M. D. Lukin, A. S. Sørensen
We discuss a new method for realizing number-resolving and non-demolition photo detectors by strong coupling of light to individual single photon emitters, which act as strong opti…
Photon scattering by a three-level emitter in a one-dimensional waveguide
D. Witthaut, A. S. Sorensen
We discuss the scattering of photons from a three-level emitter in a one-dimensional waveguide, where the transport is governed by the interference of spontaneously emitted and dir…
Scalable Quantum Networks based on Few-Qubit Registers
L. Jiang, J. M. Taylor, A. S. Sørensen +1
We describe and analyze a hybrid approach to scalable quantum computation based on an optically connected network of few-qubit quantum registers. We show that probabilistically con…
Fault-tolerant quantum repeaters with minimal physical resources, and implementations based on single photon emitters
L. I. Childress, J. M. Taylor, A. S. Sorensen +1
We analyze a novel method that uses fixed, minimal physical resources to achieve generation and nested purification of quantum entanglement for quantum communication over arbitrari…
