Sub-Doppler cooling of trapped ions using optical tweezers
Bas Gerritsen, Liam J. Bond, Jiri Minář +3
We propose a sub-Doppler cooling scheme for trapped-ion crystals in Paul traps. The combination of a hollow tweezer and microwave drive creates an effective two-level system which…
Permutation-invariant codes: a numerical study and qudit constructions
Liam J. Bond, Jiří Minář, Māris Ozols +2
We investigate Permutation-Invariant (PI) quantum error-correcting codes encoding a logical qudit of dimension in PI states using physical qudits of dimensi…
Optimal Displacement Sensing with Spin-Dependent Squeezed States
Liam J. Bond, Christophe H. Valahu, Athreya Shankar +2
Displacement sensing is a fundamental task in metrology. However, the development of quantum-enhanced sensors that fully utilize the available degrees of freedom in many-body quant…
Engineering continuous-variable entanglement in mechanical oscillators with optimal control
Maverick J. Millican, Vassili G. Matsos, Christophe H. Valahu +3
We demonstrate an optimal quantum control strategy for the deterministic preparation of entangled harmonic oscillator states in trapped ions. The protocol employs dynamical phase m…
Vibrationally coupled Rydberg atom-ion molecules
Ilango Maran, Liam J. Bond, Jeremy T. Young +2
We study the occurrence of Rydberg atom-ion molecules (RAIMs) in a hybrid atom-ion system with an ion crystal trapped in a Paul trap coupled to Rydberg atoms on its either ends. To…
Open quantum dynamics with variational non-Gaussian states and the truncated Wigner approximation
Liam J. Bond, Bas Gerritsen, Jiří Minář +3
We present a framework for simulating the open dynamics of spin-boson systems by combining variational non-Gaussian states with a quantum trajectories approach. We apply this metho…
Global Variational Quantum Circuits for Arbitrary Symmetric State Preparation
Liam J. Bond, Matthew J. Davis, Jiří Minář +3
Quantum states that are symmetric under particle exchange play a crucial role in fields such as quantum metrology and quantum error correction. We use a variational circuit compose…
