Hybrid Logical-Physical Qubit Interaction as a Post Selection Oracle
Nadav Carmel, N. Katz·Jun 8, 2023
We demonstrate a property of the quantum 5-qubit stabilizer code that enables the interaction between qubits of different logical layers, and conduct a full density-matrix simulation of an interaction between a logical and a physical qubit. We use th...
Approximative Lookup-Tables and Arbitrary Function Rotations for Facilitating NISQ-Implementations of the HHL and Beyond
Petros Stougiannidis, Jonas Stein, David Bucher +3 more·Jun 8, 2023
Many promising applications of quantum computing with a provable speedup center around the HHL algorithm. Due to restrictions on the hardware and its significant demand on qubits and gates in known implementations, its execution is prohibitive on nea...
Line-graph qubit routing: from kagome to heavy-hex and more
Joris Kattemolle, S. Hariharan·Jun 8, 2023
Quantum computers have the potential to outperform classical computers, but are currently limited in their capabilities. One such limitation is the restricted connectivity between qubits, as captured by the hardware's coupling graph. This limitation ...
Exploring Unsupervised Anomaly Detection with Quantum Boltzmann Machines in Fraud Detection
Jonas Stein, Daniëlle Schuman, Magdalena Benkard +7 more·Jun 8, 2023
Anomaly detection in Endpoint Detection and Response (EDR) is a critical task in cybersecurity programs of large companies. With rapidly growing amounts of data and the omnipresence of zero-day attacks, manual and rule-based detection techniques are ...
Deterministic entangling gates with nonlinear quantum photonic interferometers
Francesco Scala, D. Nigro, D. Gerace·Jun 8, 2023
The single-photon quantum computing paradigm currently relies on the multi-port interference in linear optical devices, which is intrinsically based on probabilistic measurements outcome, and thus non-deterministic. Devising a fully deterministic, un...
Quantum Wasserstein distance between unitary operations
Xinyu Qiu, Lin Chen, Lijun Zhao·Jun 8, 2023
Quantifying the effect of noise on unitary operations is an essential task in quantum information processing. We propose the quantum Wasserstein distance between unitary operations, which shows an explanation for quantum circuit complexity and charac...
Quantum computing algorithms for inverse problems on graphs and an NP-complete inverse problem
Joonas Ilmavirta, M. Lassas, Jinpeng Lu +2 more·Jun 8, 2023
We consider an inverse problem for a finite graph $(X,E)$ where we are given a subset of vertices $B\subset X$ and the distances $d_{(X,E)}(b_1,b_2)$ of all vertices $b_1,b_2\in B$. The distance of points $x_1,x_2\in X$ is defined as the minimal numb...
Benchmarking Quantum Surrogate Models on Scarce and Noisy Data
Jonas Stein, Michael Poppel, P. Adamczyk +9 more·Jun 8, 2023
Surrogate models are ubiquitously used in industry and academia to efficiently approximate given black box functions. As state-of-the-art methods from classical machine learning frequently struggle to solve this problem accurately for the often scarc...
Influence of HW-SW-Co-Design on Quantum Computing Scalability
Hila Safi, Karen Wintersperger, Wolfgang Mauerer·Jun 7, 2023
The use of quantum processing units (QPUs) promises speed-ups for solving computational problems. Yet, current devices are limited by the number of qubits and suffer from significant imperfections, which prevents achieving quantum advantage. To step ...

We present a modular error mitigation protocol for running bounded-error quantum polynomial time (BQP) computations on a quantum computer with time-dependent noise. Utilizing existing tools from quantum verification and measurement-based quantum comp...
Connecting classical finite exchangeability to quantum theory
Alessio Benavoli, Alessandro Facchini, Marco Zaffalon·Jun 6, 2023
Exchangeability is a fundamental concept in probability theory and statistics. It allows to model situations where the order of observations does not matter. The classical de Finetti's theorem provides a representation of infinitely exchangeable sequ...
