Generalized Hamiltonian to describe imperfections in ion-light interaction
Ming Li, Kenneth Wright, Neal C. Pisenti +3
We derive a general Hamiltonian that governs the interaction between an -ion chain and an externally controlled laser field, where the ion motion is quantized and the laser fiel…
Quantifying the efficiency of state preparation via quantum variational eigensolvers
Gabriel Matos, Sonika Johri, Zlatko Papić
Recently, there has been much interest in the efficient preparation of complex quantum states using low-depth quantum circuits, such as Quantum Approximate Optimization Algorithm (…
Vacuum Characterization of a Compact Room-temperature Trapped Ion System
Yuhi Aikyo, Geert Vrijsen, Thomas W. Noel +3
We present the design and vacuum performance of a compact room-temperature trapped ion system for quantum computing, consisting of a ultra-high vacuum (UHV) package, a micro-fabric…
Frequency Ratio Measurements with 18-digit Accuracy Using a Network of Optical Clocks
Boulder Atomic Clock Optical Network, Collaboration, : +35
Atomic clocks occupy a unique position in measurement science, exhibiting higher accuracy than any other measurement standard and underpinning six out of seven base units in the SI…
Resource-Optimized Fermionic Local-Hamiltonian Simulation on Quantum Computer for Quantum Chemistry
Qingfeng Wang, Ming Li, Christopher Monroe +1
The ability to simulate a fermionic system on a quantum computer is expected to revolutionize chemical engineering, materials design, nuclear physics, to name a few. Thus, optimizi…
High-fidelity Two-qubit Gates Using a MEMS-based Beam Steering System for Individual Qubit Addressing
Ye Wang, Stephen Crain, Chao Fang +6
In a large scale trapped atomic ion quantum computer, high-fidelity two-qubit gates need to be extended over all qubits with individual control. We realize and characterize high-fi…
