Improved quantum metrology using quantum error correction

We consider quantum metrology in noisy environments, where the effect of noise and decoherence limits the achievable gain in precision by quantum entanglement. We show that by …

Quantum metrology with full and fast quantum control

We establish general limits on how precise a parameter, eg frequency or the strength of a magnetic field, can be estimated with the aid of full and fast quantum control. We consider …

Beyond the swap test: optimal estimation of quantum state overlap

We study the estimation of the overlap between two unknown pure quantum states of a finite-dimensional system, given M and N copies of each type. This is a fundamental primitive in …

Dynamical decoupling leads to improved scaling in noisy quantum metrology

We consider the usage of dynamical decoupling in quantum metrology, where the joint evolution of system plus environment is described by a Hamiltonian. We show that by ultra-fast …

Accessible coherence in open quantum system dynamics

Quantum coherence generated in a physical process can only be cast as a potentially useful resource if its effects can be detected at a later time. Recently, the notion of non-coherence-…
