Reconstructing the phonon distribution of trapped ions out of the Lamb-Dicke regime
Christophe H. Valahu, Prachi Nagpal, Teerawat Chalermpusitarak +6
Characterizing the phonon distribution of trapped-ion motional states is essential for many applications in quantum information processing, but existing methods become ill-conditio…
Programmable quantum simulation of anharmonic dynamics
Cameron McGarry, Teerawat Chalermpusitarak, Kai Schwennicke +9
Continuous-variable-discrete-variable (CV-DV) quantum simulators offer a natural route to simulating bosonic dynamics relevant to many branches of physics and chemistry. However, p…
Programmable generation of arbitrary continuous-variable anharmonicities and nonlinear couplings
Teerawat Chalermpusitarak, Kai Schwennicke, Ivan Kassal +1
Harmonic oscillators are promising continuous-variable (CV) quantum resources because their infinite-dimensional Hilbert spaces allow for resource-efficient quantum computing and s…
Quantum-Enhanced Multi-Parameter Sensing in a Single Mode
Christophe H. Valahu, Matthew P. Stafford, Zixin Huang +7
Precision metrology underpins scientific and technological advancements. Quantum metrology offers a pathway to surpass classical sensing limits by leveraging quantum states and mea…
Frame-Based Filter-Function Formalism for Quantum Characterization and Control
Teerawat Chalermpusitarak, Behnam Tonekaboni, Yuanlong Wang +3
We introduce a theoretical framework for resource-efficient characterization and control of non-Markovian open quantum systems, which naturally allows for the integration of given,…
Quantum state tomography with time-continuous measurements: reconstruction with resource limitations
Areeya Chantasri, Shengshi Pang, Teerawat Chalermpusitarak +1
We propose and analyze quantum state estimation (tomography) using continuous quantum measurements with resource limitations, allowing the global state of many qubits to be constru…
