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 ...

Robust Weak Measurements with Certified Single Photons

Advanced Quantum Technologies, EarlyView.
Weak values are usually extracted by statistical means, but with robust weak measurements they can be extracted by a single detection event with reasonable uncertainty. Here, robust weak measurements are experimentally implemented on certified single photons.

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 ...

Highly Sensitive Magnetometer with Continuous Excitation Ramsey Protocol by Utilizing Long Dephasing Time of Millimeter‐Scale Spin Ensembles in (111) Diamond

Advanced Quantum Technologies, EarlyView.
A highly sensitive magnetometer using a continuous excitation Ramsey protocol is demonstrated with millimeter‐scale spin ensembles in (111) diamond, achieving 15.8 pT/Hz${\mathrm{pT}}/\sqrt {{\mathrm{Hz}}} $ sensitivity at an excitation power of 160 mW.
