Effectiveness of quantum annealing for continuous-variable optimization
S. Arai, Hiroki Oshiyama, H. Nishimori·May 11, 2023
The application of quantum annealing to the optimization of continuous-variable functions is a relatively unexplored area of research. We test the performance of quantum annealing applied to a one-dimensional continuous-variable function with a rugge...
Stochastic Approximation of Variational Quantum Imaginary Time Evolution
Julien Gacon, Christa Zoufal, Giuseppe Carleo +1 more·May 11, 2023
The imaginary-time evolution of quantum states is integral to various fields, ranging from natural sciences to classical optimization or machine learning. Since simulating quantum imaginary-time evolution generally requires storing an exponentially l...
Adaptive variational simulation for open quantum systems
Huo Chen, N. Gomes, Siyuan Niu +1 more·May 11, 2023
Emerging quantum hardware provides new possibilities for quantum simulation. While much of the research has focused on simulating closed quantum systems, the real-world quantum systems are mostly open. Therefore, it is essential to develop quantum al...
Family of Quantum Codes with Exotic Transversal Gates.
Eric Kubischta, Ian Teixeira·May 11, 2023
Recently, an algorithm has been constructed that shows that the binary icosahedral group 2I together with a T-like gate forms the most efficient single-qubit universal gate set. To carry out the algorithm fault tolerantly requires a code that impleme...

Hans Johnson, S. Zorzetti, J. Saniie·May 11, 2023
This work explores avenues and target areas for optimizing FPGA-based control hardware for experiments conducted on superconducting quantum computing systems and serves as an introduction to some of the current research at the intersection of classic...
Mapping Quantum Circuits to Modular Architectures with QUBO
Medina Bandic, Luise Prielinger, Jonas Nusslein +8 more·May 11, 2023
Modular quantum computing architectures are a promising alternative to monolithic QPU (Quantum Processing Unit) designs for scaling up quantum devices. They refer to a set of interconnected QPUs or cores consisting of tightly coupled quantum bits tha...
Use VQE to calculate the ground energy of hydrogen molecules on IBM Quantum
Ma Qing, Wei Xie·May 11, 2023
Quantum computing has emerged as a promising technology for solving problems that are intractable for classical computers. In this study, we introduce quantum computing and implement the Variational Quantum Eigensolver (VQE) algorithm using Qiskit on...
Parallelizing Quantum-Classical Workloads: Profiling the Impact of Splitting Techniques
Tuhin Khare, Ritajit Majumdar, Rajiv Sangle +3 more·May 11, 2023
Quantum computers are the next evolution of computing hardware. Quantum devices are being exposed through the same familiar cloud platforms used for classical computers, and enabling seamless execution of hybrid applications that combine quantum and ...
Enabling Full-Stack Quantum Computing with Changeable Error-Corrected Qubits
Anbang Wu, Keyi Yin, Andrew W. Cross +2 more·May 11, 2023
Executing quantum applications with quantum error correction (QEC) faces the gate non-universality problem imposed by the Eastin-Knill theorem. As one resource-time-efficient solution, code switching changes the encoding of logical qubits to implemen...
Security framework for quantum key distribution with imperfect sources
Guillermo Currás-Lorenzo, Margarida Pereira, Go Kato +2 more·May 10, 2023
Imperfect bit-and-basis encoders compromise the security of quantum key distribution (QKD) systems via modulation flaws, side channels and inter-pulse correlations, which invalidate standard security proofs. Existing results addressing such imperfect...
Lifting Topological Codes: Three-Dimensional Subsystem Codes from Two-Dimensional Anyon Models
Jacob C. Bridgeman, Aleksander Kubica, M. Vasmer·May 10, 2023
Topological subsystem codes in three spatial dimensions allow for quantum error correction with no time overhead, even in the presence of measurement noise. The physical origins of this single-shot property remain elusive, in part due to the scarcity...
