Abstract We present a hybrid quantum-classical variational scheme to enhance precision in quantum metrology. In the scheme, both the initial state and the measurement basis in the quantum part are parameterized and optimized via the classical part. It enables the maximization of information gained about the measured quantity. We discuss specific applications to 3D magnetic field sensing under several dephasing noise models. Indeed, we demonstrate its ability to simultaneously estimate all parameters and surpass the standard quantum limit, making it a powerful tool for metrological applications.

Abstract Universal compilation is a training process that compiles a trainable unitary into a target unitary. It has vast potential applications from depth-circuit compressing to device benchmarking and quantum error mitigation. Here we propose a universal compilation algorithm for quantum state tomography in low-depth quantum circuits. We apply the Fubini-Study distance as a trainable cost function and employ various gradient-based optimizations. We evaluate the performance of various trainable unitary topologies and the trainability of different optimizers for getting high efficiency and reveal the crucial role of the circuit depth in robust fidelity. The results are comparable with the shadow tomography method, a similar fashion in the field. Our work expresses the adequate capability of the universal compilation algorithm to maximize the efficiency in the quantum state tomography. Further, it promises applications in quantum metrology and sensing and is applicable in the near-term quantum computers for various quantum computing tasks.

Trade-off relation between integrated metrological gain and local dissipation in magnetic-field sensing by quantum spin ensemble

More details Close

Quantum metrology plays a central role in precision sensing, where quantum enhancement of detection performance is crucial for both fundamental studies and practical applications. In this work, we derive a tight performance bound for magnetic-field sensing with a spin ensemble in the presence of dissipation. The metrological performance is quantified by the integrated metrological gain (IMG), which explicitly incorporates the time evolution of the measurement apparatus. By combining the Lindblad master equation with the quantum Fisher information, we obtain analytically exact trade-off relations between the IMG and the dissipation rate for local dephasing and local emission processes, showing that the gain scales inversely with the dissipation strength. This trade-off complements the Heisenberg limit, which addresses only the scaling with the number of spins and neglects dissipative dynamics. We analyze various initial state preparations and elucidate the role of quantum entanglement in the presence of dissipation. Notably, while entanglement is essential for achieving Heisenberg scaling at short times, it also accelerates dissipative degradation during time evolution. Consequently, for sufficiently long observation times, comparable metrological performance can be achieved even without entanglement.
Quantum simulation of strong Charge-Parity violation and Peccei-Quinn mechanism

Quantum Chromodynamics (QCD) admits a topological $\barθ$-term that violates Charge-Parity $(CP)$ symmetry, yet experimental indicate that $\barθ$ is nearly zero. To investigate this discrepancy in a controlled setting, we derive the Hamiltonian representation of the QCD Lagrangian and construct its $(1{+}1)$-dimensional Schwinger-model analogue. By encoding fermionic and gauge degrees of freedom into qubits using the Jordan-Wigner and quantum-link schemes, we obtain a compact Pauli Hamiltonian that retains the relevant topological vacuum structure. Ground states are evaluated using a feedback-based quantum optimization protocol, enabling numerical evaluation of the vacuum energy $E_0(\barθ)$ on a few-qubit simulator. Our results show a vacuum at $\barθ= 0\ (\text{mod 2})$ in agreement with strong-interaction expectations, and demonstrate that introducing a dynamical axion field drives the system toward a $θ_{\rm eff}=0$, thereby realizing the Peccei-Quinn mechanism within a minimal quantum simulation. These results illustrate how quantum hardware can examine symmetry violation and its dynamical resolution in gauge theories.
Imaginary-time-enhanced feedback-based quantum algorithms for universal ground-state preparation

Thanh Nguyen Van Long, Lan Nguyen Tran, Le Bin Ho

2025/12/15

More details Close

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 attractive alternative to variational methods with a fully quantum feedback rule, but it fails in the presence of spectral degeneracies, where the feedback signal collapses and the evolution cannot reach the ground state. Using the Fermi-Hubbard model on lattices up to 3x3, we show that this breakdown appears at half-filling on the 2x2 lattice and extends to both half-filled and doped configurations on the 3x3 lattice. We then introduce an imaginary-time-enhanced FALQON (ITE-FALQON) scheme, which inserts short imaginary-time evolution steps into the feedback loop. The hybrid method suppresses excited-state components, escapes degenerate subspaces, and restores monotonic energy descent. The ITE-FALQON achieves a reliable ground-state convergence across all fillings, providing a practical route to scalable ground-state preparation in strongly correlated quantum systems.
Flexible Genetic Algorithm for Quantum Support Vector Machines

2025/11/24

More details Close

Quantum Support Vector Machines (QSVM) is one of the most promising frameworks in quantum machine learning, yet their performance depends on the design of the feature map. Conventional approaches rely on fixed quantum circuits, which often fail to generalize across datasets. To address this limitation, we propose GA-QSVM, a hybrid framework that employs Genetic Algorithms (GA) to automatically optimize feature maps. The proposed method introduces a configurable framework that flexibly defines the evolutionary parameters, enabling the construction of adaptive circuits. Experimental evaluation of datasets, including Digits, Fashion, Wine, and Breast Cancer, demonstrates that GA-QSVMs achieve a comparable accuracy compared to classical SVMs and standard QSVMs. Furthermore, transfer learning results indicate that GA-QSVM's circuits generalize effectively across datasets. These findings highlight the potential of evolutionary strategies to automate and enhance kernel design for future quantum machine learning applications.
Exact gradient for universal cost functions in variational quantum algorithms

Jesus Urbaneja, Le Bin Ho

2025/09/22

More details Close

We present a universal and exact framework for gradient derivation that is valid for all differentiable cost functions in variational quantum algorithms (VQAs). The framework provides analytic gradients without relying on restrictive assumptions, thereby extending gradient-based optimization beyond conventional expectation-value settings. These gradients can be directly accessed on quantum hardware through the Hadamard and Hilbert-Schmidt tests, making the method experimentally accessible. We illustrate the approach in variational quantum compilation, where it enables efficient and stable optimization. By establishing a universal and hardware-compatible method, this work advances the scalability and reliability of VQAs.
Statistical analysis of barren plateaus in variational quantum algorithms

Le Bin Ho, Jesus Urbaneja, Sahel Ashhab

2025/08/12

More details Close

We investigate the barren plateau (BP) phenomenon in variational quantum algorithms using a statistical approach. Using Gaussian function models, we identify three distinct types of BPs. The first type, which we called localized-dip BPs, occurs in landscapes that are mostly flat but contain a dip point where the gradient is large in a small region around the minimum. The second type, called localized-gorge BPs, which are somewhat similar to the localized-dip BPs but contain a gorge line. The third type, called everywhere-flat BPs, appears when the entire landscape is uniformly flat with almost vanishing gradients, making optimization significantly more difficult. After illustrating these behaviors in the Gaussian function models, we extend the analysis to the variational quantum eigensolver (VQE). We consider two types of ansätze: the hardware-efficient ansatz and the random Pauli ansatz. For both ansätze, we only observe the everywhere-flat BPs. Using our statistical approach, we searched for localized-dip and localized-gorge BPs but found no evidence of such features in the examples studied, suggesting that everywhere-flat BPs dominate in these ansätze. Our method effectively probes landscape features by capturing the gradient scaling across parameter space, making it a useful tool for diagnosing BPs in variational algorithms. To mitigate BPs in the VQE, we employ a genetic algorithm (GA) to optimize the random gates generated in the ansätze, thereby reshaping the cost function landscape to enhance the optimization efficiency. A comparison with an unoptimized ansatz shows how the ansatz design can improve the scalability and reliability of variational quantum algorithms.
