Selected Publications

Partial-transpose-guided entanglement classes and minimum noise filtering in many-body Gaussian quantum systems

Journal Article Physical Review A · June 1, 2024 The reduction and distortion of quantum correlations in the presence of classical noise leads to varied levels of inefficiency in the availability of entanglement as a resource for quantum information processing protocols. While generically minimizing requ ... Full text Cite

Identification of a natural fieldlike entanglement resource in trapped-ion chains

Journal Article Physical Review A · June 1, 2024 The electromagnetic trapping of ion chains can be regarded as a process of nontrivial entangled quantum state preparation within Hilbert spaces of the local axial motional modes. To begin uncovering properties of this entanglement resource produced as a by ... Full text Cite

Quantum simulation of fundamental particles and forces

Journal Article Nature Reviews Physics · July 1, 2023 Key static and dynamic properties of matter — from creation in the Big Bang to evolution into subatomic and astrophysical environments — arise from the underlying fundamental quantum fields of the standard model and their effective descriptions. However, t ... Full text Cite

Entanglement structures in quantum field theories. II. Distortions of vacuum correlations through the lens of local observers

Journal Article Physical Review A · July 1, 2023 When observing a quantum field via detectors with access to only the mixed states of spatially separated, local regions - a ubiquitous experimental design - the capacity to access the full extent of distributed entanglement can be limited, shrouded by clas ...

Entanglement structures in quantum field theories: Negativity cores and bound entanglement in the vacuum

Journal Article Physical Review A · January 1, 2023 The many-body entanglement between two finite (size-d) disjoint vacuum regions of noninteracting lattice scalar field theory in one spatial dimension, i.e., a (dA×dB)mixed Gaussian continuous variable system, is locally transformed into a tensor-product co ...

Standard model physics and the digital quantum revolution: thoughts about the interface.

Journal Article Reports on progress in physics. Physical Society (Great Britain) · May 2022 Advances in isolating, controlling and entangling quantum systems are transforming what was once a curious feature of quantum mechanics into a vehicle for disruptive scientific and technological progress. Pursuing the vision articulated by Feynman, a conce ... Full text Cite

Entanglement Spheres and a UV-IR Connection in Effective Field Theories.

Journal Article Physical review letters · November 2021 We show that long-distance quantum correlations probe short-distance physics. Two disjoint regions of the latticized, massless scalar field vacuum are numerically demonstrated to become separable at distances beyond the negativity sphere, which extends to ... Full text Cite

Fixed-point quantum circuits for quantum field theories

Journal Article Physical Review A · November 30, 2020 Full text Cite

Digitization of scalar fields for quantum computing

Journal Article Physical Review A · May 23, 2019 Full text Cite

Entanglement Suppression and Emergent Symmetries of Strong Interactions.

Journal Article Physical review letters · March 2019 Entanglement suppression in the strong-interaction S matrix is shown to be correlated with approximate spin-flavor symmetries that are observed in low-energy baryon interactions, the Wigner SU(4) symmetry for two flavors and an SU(16) symmetry for three fl ...
