Detuning-robust Rydberg entangling gates from echoed pulses
Zhubing Jia, Yichao Yu, Xiye Hu +4
Rydberg-based two-qubit gate fidelities in neutral atom arrays are limited chiefly by laser intensity inhomogeneity and by detuning errors from frequency miscalibration, background…
Nonlocal Games as Cross-Platform Quantum Benchmarks: Exceeding unconditional classical bounds on trapped-ion processors
Anton T. Than, Jim Furches, Debopriyo Biswas +15
Nonlocal games provide application-level benchmarks for quantum hardware whose classical performance bounds are information-theoretic, holding against all classical strategies rega…
Photonic Networking of Quantum Memories in High-Dimensions
Mikhail Shalaev, Sagnik Saha, George Toh +6
Quantum networking enables the exchange of quantum information between physically separated quantum systems, which has applications ranging from quantum computing to unconditionall…
In-situ mid-circuit qubit measurement and reset in a single-species trapped-ion quantum computing system
Yichao Yu, Keqin Yan, Debopriyo Biswas +5
We implement in-situ mid-circuit measurement and reset (MCMR) operations on a trapped-ion quantum computing system by using metastable qubit states in ions. W…
Non-invasive mid-circuit measurement and reset on atomic qubits
Zuo-Yao Chen, Isabella Goetting, George Toh +8
Mid-circuit measurement and reset of subsets of qubits is a crucial ingredient of quantum error correction and many quantum information applications. Measurement of atomic qubits i…
Entanglement fidelity limits of photonically-networked atomic qubits from recoil and timing
Yichao Yu, Sagnik Saha, Mikhail Shalaev +5
The remote entanglement of two atomic quantum memories through photonic interactions is accompanied by atomic momentum recoil. When the interactions occur at different times, such…
