In-orbit operation of a programmable quantum photonic processor
Simon Steiner, Peter Schiansky, Antonius Scherer +17
Quantum technologies promise computational capabilities beyond the reach of classical systems. A forward-looking application lies in satellite missions, which increasingly depend o…
Performance of Practical Quantum Oblivious Key Distribution
Mariano Lemus, Peter Schiansky, Manuel Goulão +5
Motivated by the applications of secure multiparty computation as a privacy-protecting data analysis tool, and identifying oblivious transfer as one of its main practical enablers,…
Demonstration of Hardware Efficient Photonic Variational Quantum Algorithm
Iris Agresti, Koushik Paul, Peter Schiansky +10
Quantum computing has brought a paradigm change in computer science, where non-classical technologies have promised to outperform their classical counterpart. Such an advantage was…
A prescriptive method for fibre polarisation compensation in two bases
Teodor Strömberg, Peter Schiansky, Philip Walther
Single-mode optical fibres exhibit a small but non-negligible birefringence that induces random polarisation rotations during light propagation. In classical interferometry these r…
Demonstration of quantum-digital payments
Peter Schiansky, Julia Kalb, Esther Sztatecsny +5
Digital payments have replaced physical banknotes in many aspects of our daily lives. Similarly to banknotes, they should be easy to use, unique, tamper-resistant and untraceable,…
Demonstration of a quantum SWITCH in a Sagnac configuration
Teodor Strömberg, Peter Schiansky, Robert W. Peterson +2
The quantum SWITCH is an example of a process with an indefinite causal structure, and has attracted attention for its ability to outperform causally ordered computations within th…
Experimental superposition of time directions
Teodor Strömberg, Peter Schiansky, Marco Túlio Quintino +5
In the macroscopic world, time is intrinsically asymmetric, flowing in a specific direction, from past to future. However, the same is not necessarily true for quantum systems, as…
Demonstration of universal time-reversal for quantum processes
Peter Schiansky, Teodor Strömberg, David Trillo +4
Although the laws of classical physics are deterministic, thermodynamics gives rise to an arrow of time through irreversible processes. In quantum mechanics the unitary nature of t…
Experimental quantum speed-up in reinforcement learning agents
Valeria Saggio, Beate E. Asenbeck, Arne Hamann +10
Increasing demand for algorithms that can learn quickly and efficiently has led to a surge of development within the field of artificial intelligence (AI). An important paradigm wi…
Realistic Simulations of Stellar Surface Convection with ANTARES: I. Boundary Conditions and Model Relaxation
H. Grimm-Strele, F. Kupka, B. Löw-Baselli +3
We have implemented open boundary conditions into the ANTARES code to increase the realism of our simulations of stellar surface convection. Even though we greatly benefit from the…
