Model-Independent Simulation Complexity of Complex Quantum Dynamics
Aiman Khan, David Quigley, Max Marcus +2
We present a model-independent measure of dynamical complexity based on simulating complex quantum dynamics using stroboscopic Markovian dynamics. Tools from classical signal proce…
Attainability of the Holevo-Cramér-Rao bound for two-qubit 3D magnetometry
Jamie Friel, Pantita Palittapongarnpim, Francesco Albarelli +1
We study quantum-limited 3D magnetometry using two qubits. Two qubits form the smallest multi-qubit system for 3D magnetometry, the simultaneous estimation of three phases, as it i…
Approaching quantum-limited metrology with imperfect detectors by using weak-value amplification
Liang Xu, Zexuan Liu, Animesh Datta +4
Weak value amplification (WVA) is a metrological protocol that amplifies ultra-small physical effects. However, the amplified outcomes necessarily occur with highly suppressed prob…
Quantum-enhanced stimulated emission microscopy
Gil Triginer Garces, Helen M. Chrzanowski, Shakib Daryanoosh +6
Nonlinear optical microscopy techniques have emerged as a set of successful tools for biological imaging. Stimulated emission microscopy belongs to a small subset of pump-probe tec…
