Quantum Darwinism through apparatus-mediated environmental recording
Tran P. H Don, Lan Nguyen Tran, Le Bin Ho
Quantum Darwinism explains classical objectivity through redundant environmental records of a system's pointer states. We show that these records can be established through an inte…
Qmes: Quantum Meta-Learning for Encoding Selection in Quantum Kernel Methods
Dao Duy Tung, Quoc Chuong Nguyen, Vu Tuan Hai +2
Selecting an effective encoding quantum circuit is a key challenge in quantum kernel methods because different feature maps can lead to different performance. Conventional methods…
Multiparameter sensing of axion dark matter with superconducting-qubit networks
Le Bin Ho
We propose a quantum sensor network for direct detection of quantum chromodynamics (QCD) axion dark matter using entangled superconducting qubits. In the presence of a static magne…
Analytic correspondence between multipartite entanglement and quantum phase transitions
Huynh Le Dan Linh, Vu Tuan Hai, Le Bin Ho
We derive an analytic correspondence between multipartite concentratable entanglement (CE) and quantum phase transitions in one-dimensional quantum spin systems. We prove that CE s…
Benchmarking loss functions for trainable quantum feature maps
Nguyen Dinh Quyen, Vu Tuan Hai, Quoc Chuong Nguyen +2
Many quantum machine learning models employ quantum feature maps to encode classical data into quantum states. While fixed feature maps often lack sufficient expressivity for compl…
Measurement Geometry as a Resource for Certifying Network Nonlocality
Leon Adachi, Le Bin Ho
Quantum networks can exhibit nonclassical correlations that cannot be explained by classical models with independent sources. While the role of entanglement is well understood, the…
Towards Automated Selection of Quantum Encoding Circuits via Meta-Learning
Dao Duy Tung, Nguyen Quoc Chuong, Vu Tuan Hai +2
In recent years, quantum kernel methods have shown promising applications on near-term quantum devices. However, selecting an appropriate encoding circuit for a given dataset requi…
Imaginary-time-enhanced feedback-based quantum algorithms for universal ground-state preparation
Thanh Nguyen Van Long, Lan Nguyen Tran, Le Bin Ho
Preparing ground states of strongly correlated quantum systems is a central goal in quantum simulation and optimization. The feedback-based quantum algorithm (FALQON) provides an a…
Quantum simulation of strong charge-parity violation and Peccei-Quinn mechanism
Le Bin Ho
Quantum Chromodynamics (QCD) admits a topological term that violates charge-parity () symmetry, yet experiments indicate that is extremely small. To investigate…
Exact gradient for general cost functions in variational quantum algorithms
Jesus Urbaneja, Le Bin Ho
We present a unitary-based gradient formulation for variational quantum algorithms (VQAs) that applies to general differentiable cost function defined by a parameterized quantum ci…
Statistical analysis of barren plateaus in variational quantum algorithms
Le Bin Ho, Jesus Urbaneja, Sahel Ashhab
We investigate the barren plateau (BP) phenomenon in variational quantum algorithms using a statistical approach. Using Gaussian function models, we identify three distinct types o…
Multi-target quantum compilation algorithm
Vu Tuan Hai, Nguyen Tan Viet, Jesus Urbaneja +3
Quantum compilation is the process of converting a target unitary operation into a trainable unitary represented by a quantum circuit. It has a wide range of applications, includin…
Variational preparation of entangled states on quantum computers
Vu Tuan Hai, Nguyen Tan Viet, Le Bin Ho
We propose a variational approach for preparing entangled quantum states on quantum computers. The methodology involves training a unitary operation to match with a target unitary…
Qsun: an open-source platform towards practical quantum machine learning applications
Chuong Nguyen Quoc, Le Bin Ho, Lan Nguyen Tran +1
Currently, quantum hardware is restrained by noises and qubit numbers. Thus, a quantum virtual machine that simulates operations of a quantum computer on classical computers is a v…
