Automatic Implementation and Evaluation of Error-Correcting Codes for Quantum Computing: An Open-Source Framework for Quantum Error Correction
Thomas Grurl, Christoph Pichler, Jürgen Fuß +1 more·Jan 1, 2023
Due to the fragility of quantum mechanical effects, real quantum computers are plagued by frequent noise effects that cause errors during computations. Quantum error-correcting codes address this problem by providing means to identify and correct cor...
Quantum Representations of Sound: from mechanical waves to quantum circuits

Robustness of variational quantum algorithms against stochastic parameter perturbation
D. Rabinovich, E. Campos, Soumik Adhikary +3 more·Dec 30, 2022
Variational quantum algorithms are tailored to perform within the constraints of current quantum devices, yet they are limited by performance-degrading errors. In this study, we consider a noise model that reflects realistic gate errors inherent to v...
NISQ-ready community detection based on separation-node identification
Jonas Stein, Dominik Ott, Mirco Schoenfeld +1 more·Dec 30, 2022
The analysis of network structure is essential to many scientific areas ranging from biology to sociology. As the computational task of clustering these networks into partitions, i.e., solving the community detection problem, is generally NP-hard, he...
Investigation of Perturbation Theory with Variational Quantum Algorithm
H. Yeganeh·Dec 30, 2022
Variational Quantum Algorithms are among the most promising systems to implement quantum computing under the Noisy-Intermediate Scale Quantum (NISQ) technology. In variational quantum algorithm, wavefunction represented by a parametrized ansatz and v...
Quantum Circuit Resizing
Movahhed Sadeghi, Soheil Khadirsharbiyani, M. Kandemir·Dec 30, 2022
—Existing quantum systems provide very limited phys- ical qubit counts, trying to execute a quantum algorithm/circuit on them that have a higher number of logical qubits than physically available lead to a compile-time error. Given that it is unreali...
FIPS Compliant Quantum Secure Communication Using Quantum Permutation Pad
Alex He, Dafu Lou, Eric She +5 more·Dec 30, 2022
Quantum computing has entered a fast development track since Shor's algorithm was proposed in 1994. Multi-cloud services of quantum computing farms are currently available. One of which, IBM quantum computing, presented a road map showing their Kooka...
Tailoring Fusion-Based Error Correction for High Thresholds to Biased Fusion Failures.
K. Sahay, J. Claes, S. Puri·Dec 30, 2022
We introduce fault-tolerant (FT) architectures for error correction with the XZZX cluster state based on performing measurements of two-qubit Pauli operators Z⊗Z and X⊗X, or fusions, on a collection of few-body entangled resource states. Our construc...
