The subthreshold issue of fusion-based quantum computing
Matthias C. Löbl, Love A. M. Pettersson, Jan Dragašević +2
Fusion-based quantum architectures are the leading approach to photonic quantum computing. However, the sub-threshold regime, where logical error rates must reach the levels requir…
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…
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…
Long-distance quantum communication using concatenated ring graph codes
Love Pettersson, Anders S. Sørensen
To realize long-distance quantum communication, it is crucial to design quantum repeater architectures that can deal with transmission losses and operational errors. Code concatena…
Generating graph states with a single quantum emitter and the minimum number of fusions
Matthias C. Löbl, Love A. Pettersson, Andrew Jena +3
Graph states are the key resources for measurement- and fusion-based quantum computing with photons, yet their creation is experimentally challenging. We optimize a hybrid graph-st…
Tailoring fusion-based photonic quantum computing schemes to quantum emitters
Ming Lai Chan, Thomas J. Bell, Love A. Pettersson +4
Fusion-based quantum computation is a promising quantum computing model where small-sized photonic resource states are simultaneously entangled and measured by fusion gates. Such o…
Deterministic generation of concatenated graph codes from quantum emitters
Love A. Pettersson, Anders S. Sørensen, Stefano Paesani
Photon loss is the dominant noise mechanism in photonic quantum technologies. Designing fault-tolerant schemes with high tolerance to loss is thus a central challenge in scaling ph…
Transforming graph states via Bell state measurements
Matthias C. Löbl, Love A. Pettersson, Stefano Paesani +1
Graph states are key resources for measurement-based quantum computing, which is particularly promising for photonic systems. Fusions are probabilistic Bell state measurements, mea…
Optimising graph codes for measurement-based loss tolerance
Tom J. Bell, Love A. Pettersson, Stefano Paesani
Graph codes play an important role in photonic quantum technologies as they provide significant protection against qubit loss, a dominant noise mechanism. Here, we develop methods…
