Quantum Simulation of Polarized Light-induced Electron Transfer with A Trapped-ion Qutrit System
Ke Sun, Chao Fang, Mingyu Kang +5
Electron transfer within and between molecules is crucial in chemistry, biochemistry, and energy science. This study describes a quantum simulation method that explores the influen…
Realization of Scalable Cirac-Zoller Multi-Qubit Gates
Chao Fang, Ye Wang, Ke Sun +1
The universality theorem in quantum computing states that any quantum computational task can be decomposed into a finite set of logic gates operating on one and two qubits. However…
Simulating conical intersections with trapped ions
Jacob Whitlow, Zhubing Jia, Ye Wang +3
Conical intersections are common in molecular physics and photochemistry, and are often invoked to explain observed reaction products. A conical intersection can occur when an exci…
Modular Software for Real-Time Quantum Control Systems
Leon Riesebos, Brad Bondurant, Jacob Whitlow +9
Real-time control software and hardware is essential for operating quantum computers. In particular, the software plays a crucial role in bridging the gap between quantum programs…
Crosstalk Suppression in Individually Addressed Two-Qubit Gates in a Trapped-Ion Quantum Computer
Chao Fang, Ye Wang, Shilin Huang +2
Crosstalk between target and neighboring spectator qubits due to spillover of control signals represents a major error source limiting the fidelity of two-qubit entangling gates in…
Designing Filter Functions of Frequency-Modulated Pulses for High-Fidelity Two-Qubit Gates in Ion Chains
Mingyu Kang, Ye Wang, Chao Fang +4
High-fidelity two-qubit gates in quantum computers are often hampered by fluctuating experimental parameters. The effects of time-varying parameter fluctuations lead to coherent no…
Determination of Multi-mode Motional Quantum States in a Trapped Ion System
Zhubing Jia, Ye Wang, Bichen Zhang +4
Trapped atomic ions are a versatile platform for studying interactions between spins and bosons by coupling the internal states of the ions to their motion. Measurement of complex…
High stability cryogenic system for quantum computing with compact packaged ion traps
Robert F. Spivey, Ismail V. Inlek, Zhubing Jia +9
Cryogenic environments benefit ion trapping experiments by offering lower motional heating rates, collision energies, and an ultra-high vacuum (UHV) environment for maintaining lon…
Batch Optimization of Frequency-Modulated Pulses for Robust Two-qubit Gates in Ion Chains
Mingyu Kang, Qiyao Liang, Bichen Zhang +5
Two-qubit gates in trapped-ion quantum computers are generated by applying spin-dependent forces that temporarily entangle the internal state of the ion with its motion. Laser puls…
Hidden Inverses: Coherent Error Cancellation at the Circuit Level
Bichen Zhang, Swarnadeep Majumder, Pak Hong Leung +6
Coherent gate errors are a concern in many proposed quantum computing architectures. These errors can be effectively handled through composite pulse sequences for single-qubit gate…
