Efficient Computation of the Quantum Rate-Distortion Function
Kerry He, J. Saunderson, Hamza Fawzi·Sep 28, 2023
The quantum rate-distortion function plays a fundamental role in quantum information theory, however there is currently no practical algorithm which can efficiently compute this function to high accuracy for moderate channel dimensions. In this paper...
Group twirling and noise tailoring for multiqubit controlled phase gates
Guoding Liu, Ziyi Xie, Zitai Xu +1 more·Sep 27, 2023
Group twirling is crucial in quantum information processing, particularly in randomized benchmarking and randomized compiling. While protocols based on Pauli twirling have been effectively crafted to transform arbitrary noise channels into Pauli chan...
Quantum computer-enabled receivers for optical communication
J.C. Crossman, Spencer Dimitroff, Lukasz Cincio +1 more·Sep 27, 2023
Optical communication is the standard for high-bandwidth information transfer in today’s digital age. The increasing demand for bandwidth has led to the maturation of coherent transceivers that use phase- and amplitude-modulated optical signals to en...
Quantum Information Driven Ansatz (QIDA): Shallow-Depth Empirical Quantum Circuits from Quantum Chemistry.
Davide Materia, Leonardo Ratini, Celestino Angeli +1 more·Sep 26, 2023
Hardware-efficient empirical variational ansätze for Variational Quantum Eigensolver (VQE) simulations of quantum chemistry often lack a direct connection to classical quantum chemistry methods. In this work, we propose a method to bridge this gap by...
Statistical Analysis of Quantum State Learning Process in Quantum Neural Networks
Hao Zhang, Chenghong Zhu, M. Jing +1 more·Sep 26, 2023
Quantum neural networks (QNNs) have been a promising framework in pursuing near-term quantum advantage in various fields, where many applications can be viewed as learning a quantum state that encodes useful data. As a quantum analog of probability d...
Quantum Superpositions of Conscious States in a Minimal Integrated Information Model
Kelvin J. McQueen, Ian T. Durham, Markus P. Mueller·Sep 25, 2023
Could there be quantum superpositions of conscious states, as suggested by the Wigner's friend thought experiment? Mathematical theories of consciousness, notably Integrated Information Theory (IIT), make this question more precise by associating phy...
Quantum Memory: A Missing Piece in Quantum Computing Units
Chenxu Liu, M. Wang, S. Stein +2 more·Sep 25, 2023
Memory is an indispensable component in classical computing systems. While the development of quantum computing is still in its early stages, current quantum processing units mainly function as quantum registers. Consequently, the actual role of quan...
Completeness of qufinite ZXW calculus, a graphical language for finite-dimensional quantum theory
Quanlong Wang, Boldizsár Poór, Razin A. Shaikh·Sep 22, 2023
Finite-dimensional quantum theory serves as the theoretical foundation for quantum information and computation. Mathematically, it is formalized in the category FHilb, comprising all finite-dimensional Hilbert spaces and linear maps between them. How...
Dynamical subset sampling of quantum error-correcting protocols

Quantum error correcting (QEC) stabilizer codes enable protection of quantum information against errors during storage and processing. Simulation of noisy QEC codes is used to identify the noise parameters necessary for advantageous operation of logi...
Encoding optimization for quantum machine learning demonstrated on a superconducting transmon qutrit
Shuxiang Cao, Weixi Zhang, Jules Tilly +9 more·Sep 22, 2023
A qutrit represents a three-level quantum system, so that one qutrit can encode more information than a qubit, which corresponds to a two-level quantum system. This work investigates the potential of qutrit circuits in machine learning classification...
