Demonstration of a logical Bell-state measurement beyond the linear-optical limit
Shreya Kumar, Simon D. Reiß, Peter van Loock +1
Fault tolerance is essential for scalable quantum technologies and is enabled by quantum error-correction codes. Bell-state measurements (BSMs) are a fundamental building block for…
Plaquette: A hardware-aware design platform for fault-tolerant quantum computers
Raul Conchello Vendrell, Carlos Díaz López, Ish Dhand +12
Hardware teams building fault-tolerant quantum computers (FTQCs) must decide which imperfections to suppress, and that decision requires the logical performance of the architecture…
Exchange Symmetry in Multiphoton Quantum Interference
Shreya Kumar, Alex E Jones, Daniel Bhatti +1
Photons are bosons, and yet, when prepared in specific entangled states, they can exhibit non-bosonic behaviour. While this phenomenon has so far been studied in two-photon systems…
Integrated high-fidelity preparation and analysis of photonic two-qubit states for quantum network nodes
Jonas C. J. Zatsch, Tim Engling, Jeldrik Huster +3
The realisation of quantum networks requires local quantum information processing at the network nodes and highly efficient transmission of quantum information across the network.…
Multiphoton Quantum Interference at Ultracompact Inverse-Designed Multiport Beam Splitter
Shiang-Yu Huang, Shreya Kumar, Jeldrik Huster +3
Photonic quantum technologies enter a new phase when realized in photonic integrated circuits, leading to a great advance in practical applications. In the pursuit of high integrat…
Boosted Bell-state measurements for photonic quantum computation
Nico Hauser, Matthias J. Bayerbach, Simone E. D'Aurelio +5
Fault-tolerant fusion-based photonic quantum computing (FBQC) greatly relies on entangling two-photon measurements, called fusions. These fusions can be realized using linear-optic…
Experimental entanglement generation using multiport beam splitters
Shreya Kumar, Daniel Bhatti, Alex E. Jones +1
Multi-photon entanglement plays a central role in optical quantum technologies. One way to entangle two photons is to prepare them in orthogonal internal states, for example, in tw…
Distinguishability and mixedness in quantum interference
Alex E Jones, Shreya Kumar, Simone D'Aurelio +3
We study the impact of distinguishability and mixedness -- two fundamental properties of quantum states -- on quantum interference. We show that these can influence the interferenc…
On Quantum Gravity Tests with Composite Particles
Shreya P. Kumar, Martin B. Plenio
Models of quantum gravity imply a fundamental revision of our description of position and momentum that manifests in modifications of the canonical commutation relations. Experimen…
Quantum-optical tests of Planck-scale physics
Shreya P. Kumar, Martin B. Plenio
Recently it was proposed to use cavity-optomechanical systems to test for quantum gravity corrections to quantum canonical commutation relations [Nat. Phys. 8, 393-397 (2012)]. Imp…
