Quantum-Informed Portfolio Selection: An End-to-End Pipeline Validated on Trapped-Ion Hardware with Real Market Data
Romina Yalovetzky, Martin J. A. Schuetz, Zichang He +11
Portfolio diversification - a cornerstone of modern investment management - can be formulated as a Maximum Independent Set (MIS) problem on asset correlation graphs. Solving this p…
qReduMIS: A Quantum-Informed Reduction Algorithm for the Maximum Independent Set Problem
Martin J. A. Schuetz, Romina Yalovetzky, Ruben S. Andrist +8
We propose and implement a quantum-informed reduction algorithm for the maximum independent set problem that integrates classical kernelization techniques with information extracte…
Quantum Compilation Toolkit for Rydberg Atom Arrays with Implications for Problem Hardness and Quantum Speedups
Martin J. A. Schuetz, Ruben S. Andrist, Grant Salton +7
We propose and implement a comprehensive quantum compilation toolkit for solving the maximum independent set (MIS) problem on quantum hardware based on Rydberg atom arrays. Our end…
Hardness of the Maximum Independent Set Problem on Unit-Disk Graphs and Prospects for Quantum Speedups
Ruben S. Andrist, Martin J. A. Schuetz, Pierre Minssen +9
Rydberg atom arrays are among the leading contenders for the demonstration of quantum speedups. Motivated by recent experiments with up to 289 qubits [Ebadi et al., Science 376, 12…
Error tolerance of topological codes with independent bit-flip and measurement errors
Ruben S. Andrist, Helmut G. Katzgraber, H. Bombin +1
Topological quantum error correction codes are currently among the most promising candidates for efficiently dealing with the decoherence effects inherently present in quantum devi…
Error Thresholds for Abelian Quantum Double Models: Increasing the bit-flip Stability of Topological Quantum Memory
Ruben S. Andrist, James R. Wootton, Helmut G. Katzgraber
Current approaches for building quantum computing devices focus on two-level quantum systems which nicely mimic the concept of a classical bit, albeit enhanced with additional quan…
Optimal error correction in topological subsystem codes
Ruben S. Andrist, H. Bombin, Helmut G. Katzgraber +1
A promising approach to overcome decoherence in quantum computing schemes is to perform active quantum error correction using topology. Topological subsystem codes incorporate both…
Strong Resilience of Topological Codes to Depolarization
H. Bombin, Ruben S. Andrist, Masayuki Ohzeki +2
The inevitable presence of decoherence effects in systems suitable for quantum computation necessitates effective error-correction schemes to protect information from noise. We com…
Tricolored Lattice Gauge Theory with Randomness: Fault-Tolerance in Topological Color Codes
Ruben S. Andrist, Helmut G. Katzgraber, H. Bombin +1
We compute the error threshold of color codes, a class of topological quantum codes that allow a direct implementation of quantum Clifford gates, when both qubit and measurement er…
Topological color codes on Union Jack lattices: A stable implementation of the whole Clifford group
Helmut G. Katzgraber, H. Bombin, Ruben S. Andrist +1
We study the error threshold of topological color codes on Union Jack lattices that allow for the full implementation of the whole Clifford group of quantum gates. After mapping th…
