Two Variations of Quantum Phase Estimation for Reducing Circuit Error Rates: Application to the Harrow--Hassidim--Lloyd Algorithm
We introduce two variations of the quantum phase estimation algorithm: quantum shifted phase estimation and quantum punctured phase estimation. The shifted method employs a bit-string left shift to discard the most significant bit and focus on lower-order phase components, and the punctured method removes qubits corresponding to known phase bits, thereby streamlining the circuit. To demonstrate the effectiveness of the two variations, we integrate them into a hybrid quantum-classical implementa…

Wisst ihr was ich bei Youtube echt traurig finde, das User nicht mehr beachtet werden, die einfach nur ein einfaches Video hochladen wollen. Ohne gross da Geld verdienen zu wollen, alle sind so sehr auf dieses "Geld verdienen" fokussiert, das das sie die anderen "kleinen" einfach zur Seite geschoben werden.
Vielleicht ist genau für diese Menschen so Portal wie Peertube genau richtig, die auf Reichweite schei**en und ihre Videos, ob nun gut oder nicht, da hochladen …

Variational Quantum Circuits in Offline Contextual Bandit Problems
This paper explores the application of variational quantum circuits (VQCs) for solving offline contextual bandit problems in industrial optimization tasks. Using the Industrial Benchmark (IB) environment, we evaluate the performance of quantum regression models against classical models. Our findings demonstrate that quantum models can effectively fit complex reward functions, identify optimal configurations via particle swarm optimization (PSO), and generalize well in noisy and sparse datasets.…

Subspace Variational Quantum Simulation: Fidelity Lower Bounds as Measures of Training Success
We propose an iterative variational quantum algorithm to simulate the time evolution of arbitrary initial states within a given subspace. The algorithm compresses the Trotter circuit into a shorter-depth parameterized circuit, which is optimized simultaneously over multiple initial states in a single training process using fidelity-based cost functions. After the whole training procedure, we provide an efficiently computable lower bound on the fidelities for arbitrary states within the subspace…

Improving fermionic variational quantum eigensolvers with Majorana swap networks
Simulating computationally hard fermionic systems is a promising application of quantum computing. However, mapping nonlocal fermionic operators to qubits often produces deep circuits, rendering such simulations impractical on near-term hardware. We introduce two Majorana swap network techniques for variational quantum eigensolvers that reduce circuit depth and two-qubit gate count, thereby limiting error accumulation. First, we develop a cyclic compilation algorithm that localizes all two-part…
