Photon Number Coherence in Quantum Dot‐Cavity Systems can be Enhanced by Phonons
Advanced Quantum Technologies, EarlyView.Photon number coherence (PNC) is important for quantum cryptography. Because of that, the PNC within a quantum dot‐cavity system is investigated theoretically. Phonons, which interact with the quantum dot, surprisingly do not necessarily decrease PNC. It is demonstrated that it is possible to optimize other figures of merit without significant penalty ...

Non‐Markovian Dynamics in Fiber Delay‐Line Buffers
Advanced Quantum Technologies, EarlyView.A qubit‐fiber birefringence‐reservoir model is proposed to explore the non‐Markovian dynamics of the fiber‐based buffered photon and its paired photon. The non‐Markovian probability function is obtained by performing full quantum state tomography. The probability function fits well with experimental data and physical values.

Efficient Simulation of Open Quantum Systems on NISQ Trapped‐Ion Hardware
Advanced Quantum Technologies, EarlyView.Open quantum systems exhibit rich dynamics that can be simulated efficiently on quantum computers, allowing us to learn more about their behavior. This work applies a new method to simulate certain open quantum systems on noisy trapped‐ion quantum hardware.

, 1997 We study a general quantum system interacting with environment modeled by the bosonic heat bath of Caldeira and Leggett type. General interaction Hamiltonians are considered that commute with the system's Hamiltonian so that there is no energy exchange between the system and bath.

Performance of a Superconducting Quantum Battery
Advanced Quantum Technologies, EarlyView.The authors introduce a scheme for superconducting quantum battery (SQB) consisting of two coupled superconducting qubits that interact during the unitary charging process while remaining in equilibrium with a thermal reservoir. This work highlights the complexities of tuning system parameters, which increase the potential for work extraction from the ...

Open and Closed Loop Approaches for Energy Efficient Quantum Optimal Control
Advanced Quantum Technologies, EarlyView.Concepts from quantum thermodynamics and optimal control are blended to derive a theoretical framework to quantify and minimize the energetic cost of a pulse for unitary synthesis. Two complementary techniques (based on GRAPE and Reinforce‐DRL) are implemented as open‐source software that co‐optimizes the fidelity and energetic cost within quantum ...

Cuprate Twistronics for Quantum Hardware
Advanced Quantum Technologies, EarlyView.This review bridges decades of foundational research with emerging fabrication techniques such as molecular beam epitaxy and cryogenic stacking. By enabling control over electronic correlations and symmetry in twisted cuprate heterostructures, it highlights how cuprate twistronics could open new paths to overcome decoherence and scalability challenges ...
