Machine learning techniques are increasingly being used in fundamental research to solve various challenging problems. Here we explore one such technique to address an important problem in quantum communication scenario. While transferring quantum in...
Systematic Literature Review: Quantum Machine Learning and its applications
David Peral Garc'ia, Juan Cruz-Benito, Francisco Jos'e Garc'ia-Penalvo·Jan 11, 2022
Quantum computing is the process of performing calculations using quantum mechanics. This field studies the quantum behavior of certain subatomic particles for subsequent use in performing calculations, as well as for large-scale information processi...
Full-Wave Methodology to Compute the Spontaneous Emission Rate of a Transmon Qubit
T. Roth, W. C. Chew·Jan 11, 2022
The spontaneous emission rate (SER) is an important figure of merit for any quantum bit (qubit), as it can play a significant role in the control and decoherence of the qubit. As a result, accurately characterizing the SER for practical devices is an...
A Full Dichotomy for $\hol^{c}$, Inspired by Quantum Computation
Miriam Backens·Jan 10, 2022
Holant problems are a family of counting problems parameterised by sets of algebraic-complex valued constraint functions, and defined on graphs. They arise from the theory of holographic algorithms, which was originally inspired by concepts from quan...
Entanglement in the quantum phases of an unfrustrated Rydberg atom array
M. O’Rourke, G. Chan·Jan 10, 2022
Recent experimental advances have stimulated interest in the use of large, two-dimensional arrays of Rydberg atoms as a platform for quantum information processing and to study exotic many-body quantum states. However, the native long-range interacti...
Quantum activation functions for quantum neural networks
Marco Maronese, C. Destri, E. Prati·Jan 10, 2022
The field of artificial neural networks is expected to strongly benefit from recent developments of quantum computers. In particular, quantum machine learning, a class of quantum algorithms which exploit qubits for creating trainable neural networks,...
Benchmarking characterization methods for noisy quantum circuits
Megan L. Dahlhauser, T. Humble·Jan 6, 2022
Effective methods for characterizing the noise in quantum computing devices are essential for programming and debugging circuit performance. Existing approaches vary in the information obtained as well as the amount of quantum and classical resources...
Quantum capsule networks
Zidu Liu, Pei-Xin Shen, Weikang Li +2 more·Jan 5, 2022
Capsule networks (CapsNets), which incorporate the paradigms of connectionism and symbolism, have brought fresh insights into artificial intelligence (AI). The capsule, as the building block of CapsNets, is a group of neurons represented by a vector ...
Collective unitary evolution with linear optics by Cartan decomposition
Wen‐Qiang Liu, Xiaoping Zhou, Hai‐Rui Wei·Jan 5, 2022
Unitary operation is an essential step for quantum information processing. We first propose an iterative procedure for decomposing a general unitary operation without resorting to controlled-NOT gate and single-qubit rotation library. Based on the re...
Qubit Assignment Using Time Reversal
E. Peters, P. Shyamsundar, A. Li +1 more·Jan 3, 2022
As the number of qubits available on noisy quantum computers grows, it will become necessary to efficiently select a subset of physical qubits to use in a quantum computation. For any given quantum program and device there are many ways to assign phy...
Robust and Efficient Hamiltonian Learning
Wenjun Yu, Jinzhao Sun, Zeyao Han +1 more·Jan 1, 2022
With the fast development of quantum technology, the sizes of both digital and analog quantum systems increase drastically. In order to have better control and understanding of the quantum hardware, an important task is to characterize the interactio...
Testing matrix product states

Devising schemes for testing the amount of entanglement in quantum systems has played a crucial role in quantum computing and information theory. Here, we study the problem of testing whether an unknown state $|\psi\rangle$ is a matrix product state ...
Algorithm and Circuit of Nesting Doubled Qubits
A. Grigoryan, S. Agaian·Jan 1, 2022
Copying the quantum states is contradictory to classical information processing since the fundamental difference between classical and quantum information is that while classical information can be copied perfectly, quantum information cannot. Howeve...
