Optimal measurement-based feedback control for a single qubit: a candidate protocol
New Journal of Physics, 2014 Feedback control of quantum systems via continuous measurement involves complex nonlinear dynamics. Except in very special cases, even for a single qubit optimal feedback protocols are unknown.

Building versatile bipartite probes for quantum metrology
New Journal of Physics, 2016 We consider bipartite systems as versatile probes for the estimation of transformations acting locally on one of the subsystems. We investigate what resources are required for the probes to offer a guaranteed level of metrological performance, when the ...

Shortcuts to adiabaticity: suppression of pair production in driven Dirac dynamics
New Journal of Physics, 2015 Achieving effectively adiabatic dynamics in finite time is a ubiquitous goal in virtually all areas of modern physics. So-called shortcuts to adiabaticity refer to a set of methods and techniques that allow us to produce in a short time the same final ...

New Journal of Physics, 2016 The instability of an atomic clock is characterized by the Allan variance, a measure widely used to describe the noise of frequency standards. We provide an explicit method to find the ultimate bound on the Allan variance of an atomic clock in the most ...

Quantum parameter estimation using multi-mode Gaussian states
New Journal of Physics, 2015 Gaussian states are of increasing interest in the estimation of physical parameters because they are easy to prepare and manipulate in experiments. In this article, we derive formulae for the optimal estimation of parameters using two- and multi-mode ...

Crossover between strong and weak measurement in interacting many-body systems
New Journal of Physics, 2016 Measurements with variable system–detector interaction strength, ranging from weak to strong, have been recently reported in a number of electronic nanosystems. In several such instances many-body effects play a significant role.

Coherent feedback that beats all measurement-based feedback protocols
New Journal of Physics, 2014 We show that when the speed of control is bounded, there is a widely applicable minimal-time control problem for which a coherent feedback protocol is optimal, and is faster than all measurement-based feedback protocols, where the latter are defined in a
