Anchored isoperimetry in percolation
Sahar Diskin, Lyuben Lichev, Ritvik Ramanan Radhakrishnan +2
We show that, for any infinite transitive graph , the infinite cluster after supercritical percolation almost surely inherits the anchored isoperimetry of . Moreover, the pro…
Steady States of a Single Trapped-Ion Spin Coupled to an Engineered Non-Markovian Bath
Anthony Vogliano, Lewis Hahn, Fabien Lefebvre +5
Quantum simulation of open quantum systems offers a pathway towards better understanding various non-equilibrium physics that would otherwise be challenging to study. While most op…
Time complexity in preparing metrologically useful quantum states
Carla M. Quispe Flores, Raphael Kaubruegger, Minh C. Tran +3
We investigate the fundamental time complexity, as constrained by Lieb-Robinson bounds, for preparing entangled states useful in quantum metrology. We relate the minimum time to th…
Speed limits of two-qutrit gates
Bora Basyildiz, Zhexuan Gong, Sahel Ashhab
The speed of elementary quantum gates sets a limit on the speed at which quantum circuits can be applied and, as a result, the size of the computations that can be performed on a q…
Lévy Light Cones and Critical Causality in Fractional Multiscale Quantum Ising Models
Joshua M Lewis, Zhexuan Gong, Lincoln D Carr
We study causality and criticality in a one-dimensional fractional multiscale transverse-field Ising model, where fractional derivatives generate long range interactions beyond the…
Optimal Allocation of Pauli Measurements for Low-rank Quantum State Tomography
Zhen Qin, Casey Jameson, Zhexuan Gong +2
The process of reconstructing quantum states from experimental measurements, accomplished through quantum state tomography (QST), plays a crucial role in verifying and benchmarking…
Sample-Efficient Quantum State Tomography for Structured Quantum States in One Dimension
Zhen Qin, Casey Jameson, Alireza Goldar +3
While quantum state tomography (QST) remains the gold standard for benchmarking and verifying quantum devices, it requires an exponentially large number of measurements and classic…
Optimal quantum state tomography with local informationally complete measurements
Casey Jameson, Zhen Qin, Alireza Goldar +3
Quantum state tomography (QST) remains the gold standard for benchmarking and verification of near-term quantum devices. While QST for a generic quantum many-body state requires an…
Speed limits of two-qubit gates with qudits
Bora Basyildiz, Casey Jameson, Zhexuan Gong
The speed of elementary quantum gates ultimately sets the limit on the speed at which quantum circuits can operate. For a fixed physical interaction strength between two qubits, th…
Probing non-equilibrium dissipative phase transitions with trapped-ion quantum simulators
Casey Haack, Naushad Ahmad Kamar, Daniel Paz +2
Open quantum many-body systems with controllable dissipation can exhibit novel features in their dynamics and steady states. A paradigmatic example is the dissipative transverse fi…
Error Analysis of Tensor-Train Cross Approximation
Zhen Qin, Alexander Lidiak, Zhexuan Gong +3
Tensor train decomposition is widely used in machine learning and quantum physics due to its concise representation of high-dimensional tensors, overcoming the curse of dimensional…
