Still Unsolved High-Performance Computing Challenges for up to Pre-Petascale Homogeneous Supercomputers
M. Mačernis, Vaidotas Mickus, J. Ahonen +3 more·Oct 3, 2022
: Pre-exascale High Performance Computers (HPC) can reach more than 400 Pflop/s real performance according the HPLinpack benchmarks. For nanoscience and quantum biology there are requirements for those program codes based on quantum physics algorithm...
Quantum error mitigation
Z. Cai, R. Babbush, S. Benjamin +5 more·Oct 3, 2022
For quantum computers to successfully solve real-world problems, it is necessary to tackle the challenge of noise: the errors which occur in elementary physical components due to unwanted or imperfect interactions. The theory of quantum fault toleran...
Incompatibility of optimized protection of entanglement and teleportation fdelity in the presence of decoherence
Priyanka Chowdhury·Oct 1, 2022
Entanglement is the key success of teleporting an unknown quantum state with fidelity higher than classical limit. In the presence of decoherence, entanglement decreases with the strength of interaction between quantum systems and the environment. As...
Efficient Quantum Agnostic Improper Learning of Decision Trees
Debajyoti Bera, Sagnik Chatterjee·Oct 1, 2022
The agnostic setting is the hardest generalization of the PAC model since it is akin to learning with adversarial noise. In this paper, we give a poly$(n,t,{\frac{1}{\varepsilon}})$ quantum algorithm for learning size $t$ decision trees with uniform ...
RF simulation platform of qubit control using FDSOI technology for quantum computing
H. Jacquinot, R. Maurand, G. T. F. Bada +10 more·Oct 1, 2022
In this paper, we report on simulations of an Electron Spin Resonance (ESR) RF control line for semiconductor electron spin qubits. The simulation includes both the ESR line characteristics (geometry and configuration, stack and material properties) ...
Efficient solutions of fermionic systems using artificial neural networks
E. Nordhagen, Jane M. Kim, Bryce Fore +2 more·Oct 1, 2022
In this study, we explore the similarities and differences between variational Monte Carlo techniques that employ conventional and artificial neural network representations of the ground-state wave function for fermionic systems. Our primary focus is...
Q3DE: A fault-tolerant quantum computer architecture for multi-bit burst errors by cosmic rays
Yasunari Suzuki, T. Sugiyama, T. Arai +3 more·Oct 1, 2022
Demonstrating small error rates by integrating quantum error correction (QEC) into an architecture of quantum computing is the next milestone towards scalable fault-tolerant quantum computing (FTQC). Encoding logical qubits with superconducting qubit...
Scaling Superconducting Quantum Computers with Chiplet Architectures
Kaitlin N. Smith, Gokul Subramanian Ravi, Jonathan M. Baker +1 more·Oct 1, 2022
Fixed-frequency transmon quantum computers (QCs) have advanced in coherence times, addressability, and gate fidelities. Unfortunately, these devices are restricted by the number of on-chip qubits, capping processing power and slowing progress toward ...
Unbiased quantum phase estimation
Xi Lu, Hongfei Lin·Oct 1, 2022
Quantum phase estimation algorithm (PEA) is one of the most important algorithms in early studies of quantum computation. However, we find that the PEA is not an unbiased estimation, which prevents the estimation error from achieving an arbitrarily s...
Accelerating the Training of Single Layer Binary Neural Networks using the HHL Quantum Algorithm
S. L. Alarcón, Cory E. Merkel, Martin Hoffnagle +2 more·Oct 1, 2022
Binary Neural Networks are a promising technique for implementing efficient deep models with reduced storage and computational requirements. The training of these is however, still a compute-intensive problem that grows drastically with the layer siz...

In this new computing paradigm, named quantum computing, researchers from all over the world are taking their first steps in designing quantum circuits for image processing, through a difficult process of knowledge transfer. This effort is named quan...
Quantum Fourier Addition, Simplified to Toffoli Addition
A. Paler·Sep 30, 2022
Quantum addition circuits are considered being of two types: 1) Toffolli-adder circuits which use only classical reversible gates (CNOT and Toffoli), and 2) QFT-adder circuits based on the quantum Fourier transformation. We present the first systemat...

Nafis Irtija, J. Plusquellic, E. Tsiropoulou +3 more·Sep 30, 2022
Electronic control systems used for quantum computing have become increasingly complex as multiple qubit technologies employ larger numbers of qubits with higher fidelity target. Whereas the control systems for different technologies share some simil...
Suppressing Quantum Circuit Errors Due to System Variability
P. Nation, Matthew Treinish·Sep 30, 2022
We present a quantum circuit optimization technique that takes into account the variability in error rates that is inherent across present day noisy quantum computing platforms. This method can be run post qubit routing or post-compilation, and consi...
