Multi‐Photon Fock State Generation via Selective Single Photon Subtraction in a Cascaded Waveguide QED System

Advanced Quantum Technologies, EarlyView.
This work proposes a photon subtraction scheme, termed ′photon culling′, that enables the selective extraction of a single photon based on its arrival time relative to other photons. This scheme enables the generation of multi‐photon Fock states with high fidelity and modal purity, demonstrating significant potential for quantum metrology applications ...

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 ...

Q‐fid: Quantum Circuit Fidelity Improvement with LSTM Networks

Advanced Quantum Technologies, EarlyView.
Q‐fid is introduced, an LSTM‐based fidelity prediction system accompanied by a novel metric designed to quantify the fidelity of quantum circuits. This approach frames fidelity prediction as a Time Series Forecasting problem to analyze the tokenized circuits, capturing the causal dependence of the gate sequences and their impact on overall fidelity ...

Safety Inspections and Gas Monitoring in Hazardous Mining Areas Shortly After Blasting Using Autonomous UAVs

Journal of Field Robotics, EarlyView.
ABSTRACT This article presents the first ever fully autonomous UAV (Unmanned Aerial Vehicle) mission to perform gas measurements after a real blast in an underground mine. The demonstration mission was deployed around 40 min after the blast took place, and as such realistic gas levels were measured.
