Quantum Cramer-Rao Precision Limit of Noisy Continuous Sensing
Dayou Yang, Moulik Ketkar, Koenraad Audenaert +2
Quantum sensors hold considerable promise for precision measurement, yet their capabilities are inherently constrained by environmental noise. A fundamental task in quantum sensing…
Miscibility of Binary Bose-Einstein Condensates with -wave Interaction
Min Deng, Ming Xue, Jinghan Pang +4
We investigate the ground-state phase diagram of a binary mixture of Bose-Einstein condensates (BECs) with competing interspecies - and -wave interactions. Exploiting a pseud…
Unlocking Heisenberg Sensitivity with Sequential Weak Measurement Preparation
T. B. Lantaño, Dayou Yang, K. M. R. Audenaert +2
We propose a state preparation protocol based on sequential measurements of a central spin coupled with a spin ensemble, and investigate the usefulness of the generated multi-spin…
Criticality-enhanced Electric Field Gradient Sensor with Single Trapped Ions
Theodoros Ilias, Dayou Yang, Susana F. Huelga +1
We propose and analyze a driven-dissipative quantum sensor that is continuously monitored close to a dissipative critical point. The sensor relies on the critical open Rabi model w…
Efficient Information Retrieval for Sensing via Continuous Measurement
Dayou Yang, Susana F. Huelga, Martin B. Plenio
Continuous monitoring of driven-dissipative quantum optical systems is a crucial element in the implementation of quantum metrology, providing essential strategies for achieving hi…
Criticality-Enhanced Quantum Sensing via Continuous Measurement
Theodoros Ilias, Dayou Yang, Susana F. Huelga +1
Present protocols of criticality-enhanced sensing with open quantum sensors assume direct measurement of the sensor and omit the radiation quanta emitted to the environment, thereb…
Quantum Non-demolition Measurement of a Many-Body Hamiltonian
Dayou Yang, Andrey Grankin, Lukas M. Sieberer +2
In an ideal quantum measurement, the wave function of a quantum system collapses to an eigenstate of the measured observable, and the corresponding eigenvalue determines the measur…
Quantum Scanning Microscope for Cold Atoms
Dayou Yang, Denis V. Vasilyev, Catherine Laflamme +2
We present a detailed theoretical description of an atomic scanning microscope in a cavity QED setup proposed in Phys. Rev. Lett. 120, 133601 (2018). The microscope continuously ob…
Theory of a Quantum Scanning Microscope for Cold Atoms
Dayou Yang, Catherine Laflamme, Denis Vasilyev +2
We propose and analyze a scanning microscope to monitor `live' the quantum dynamics of cold atoms in a Cavity QED setup. The microscope measures the atomic density with subwaveleng…
Analog Quantum Simulation of (1+1)D Lattice QED with Trapped Ions
Dayou Yang, Gouri Shankar Giri, Michael Johanning +3
The prospect of quantum simulating lattice gauge theories opens exciting possibilities for understanding fundamental forms of matter. Here, we show that trapped ions represent a pr…
